What's new in Wingauge version 5.0 -This release, Version 5, introduces manynew features and functions. The following describes some of the more advanced

capabilities of the product.

DYNAMIC FORM GENERATOR

Significant enhancements have been made in the area of customizability: in fact,Version 5 is so flexible that administrators can modify existing displays or evencreate entirely new ones. Consequently, operations personnel are no longer required to simply accept the way their gauging system presents information andcan fine-tune it to suit individual requirements. Multiple monitor support is alsoavailable under the Windows 2000 Professional and Windows XP Professionaloperating systems with appropriate display hardware.

DYNAMIC REPORT GENERATOR

The technology behind the Dynamic Forms Generator has been applied toproducing quality printed reports. WINGauge supports dozens of unique datafields: any of these can be used to quickly and painlessly produce professionalprinted reports. Detail lines can be selected based upon specific criteria,optionally sorted by the contents of any field, and selectable totalization lines canbe inserted. The customer's corporate logo (or any other .BMP image file) can be

7/16/2019 3900 Manual



included in the header of any report. Reports can optionally be printed in either Landscape or Portrait modes.

PLUG-IN TECHNOLOGY

A WINGauge plug-in is an external program module that can be "plugged in" at

any time. Existing installations benefit from being able to add functionality withoutotherwise modifying a working system. Systems that have unique requirementswill have new capabilities added as plug-ins: this has the effect of isolating anysite-specific functions from the standard offering. Plugin technology allowscustomers to painlessly upgrade their WINGauge operating software as newreleases are made available, while maintaining any custom features that weredeveloped for individual sites.

ADVANCED GAUGING MODULE

The Advanced Gauging Module (AGM), an integral part of the WINGaugesystem, provides a multi-loop, multi-protocol interface to field equipment. As tankfarms commonly have level gauges from different vendors, the AGM supportsover twenty different communications protocols. The AGM is capable of gaugingwith any or all of them simultaneously on up to thirty-two loops. Loop, interfaceand poll timing parameters are completely configurable by the systemadministrator. Custom protocol drivers can be developed to accommodate non-standard gauges, and can even be added to an existing Version 5 system withWINGauge’s plug-in technology.

AUTOMATIC ARCHIVER

For sites which require efficient access to historical tank data, the new

ARCHIVER feature generates a continuously-updated Microsoft Access-compatible database of real-time information. The frequency of updates, and thespecific data fields to be stored, are completely configurable by the user. Theinternal Tank Trending and Level History displays use this database, and this fileis accessible to the end user.

OPC SERVER

WINGauge now includes a server module for applications which require OPC(Open Process Control) 2.x connectivity. The user has complete control over theactual WINGauge data items which will be made available via OPC. Informationis posted on a tank-by-tank basis for easy access.

PERFORMANCE METRICS

The system monitors its' own real-time performance. Field loop scan times aswell as individual gauge polling rates and error counts are conveniently available.

7/16/2019 3900 Manual



TANK TRANSFER

MONITORING

Tank Transfers may be monitored in real-time by the MCG3900. Transfers may

be initiated at any time, and can be programmed to terminate on volumetransferred, actual volume, ending time or total running time, or any combinationof the above. SCADA-style Valve and Pump control based upon transfer activitycan be implemented using the standard L&J control modules. Running gauges(i.e. simultaneous transfers from two or more tanks to or from a single tank) arenot currently supported.

AUTOMATIC CONFIGURATION

IMPORT

Remote control of WINGauge's internal functions and data structures can be

implemented via the Automatic Configuration Importer. This feature will monitor aspecified path for a standard text file containing a list of field descriptors and anddata items, and will automatically validate and import this information whenever the file is created or modified. Any data field which can be displayed using theDynamic Form Generator may be modified with the Importer.

SITEVIEW EDITOR

A standard feature of the WINGauge system is the SiteView graphical tank-farmdisplay. This popular display shows real-time gauging data superimposed uponan aerial, satellite or CAD view of a facility. Until now, a SiteView installation

could only be configured at the factory. That limitation has been removed, as thenew SiteView Editor allows authorized personnel to easily create detailedSiteViews from standard .BMP, .JPG or .TIF image files.

FASTGAUGE DISPLAY

The new FastGauge display allows selected tanks to be polled at a higher rate.FastGauge is very useful for more precisely resolving levels and volumes intanks which are in motion, particularly at facilities with smaller tanks or high flowrates.

HISTORICALDISPLAYS

The Trending and Level History displays have been completely rewritten. TheTrending display now uses the Access-compatible database generated by the

Archiver, and allows the user to selectively graph any or all of the numeric dataitems stored in the database. Likewise, the Level History display creates atabular view of this same information, organized by day and by hour.

7/16/2019 3900 Manual



VERSATILE RATE CALCULATION

The new rate calculation module includes a sophisticated filtering algorithm toreduce the number and frequency of flow rate transients, and also has the abilityto handle extremely slow-moving or infrequently-polled tanks.

ADVANCED NETWORK MODULE

The Advanced Network Module performs several vital functions when runningWINGauge in a networked environment. It permits MCG3900 client systems toaccess live and archival data on a WINGauge server. Furthermore, this moduleallows multiple gauging servers to be linked together via a TCP/IP network toprovide a combined view of field data (Multi-field Integrated Gauging.) Thismodule also has support for fault-tolerant installations running a hot backup withan automatic switchover unit.

REAL-TIME CONNECTIVITY

Data acquired from live gauges may be exported in real-time. Data records maybe output in a variety of formats, including (but not limited to) XML, Microsoft

Access, or even comma-delimited text. Data may be transmitted via serial andnetwork links using popular protocols such as Modbus, TopTech and ProfiBus.Non-standard data interchange formats are accommodated via customWINGauge plug-in modules.

IMPROVED FIELD INTERFACE SUPPORT

The new Version 5 plug-in package has support for a number of new hardwareitems, and improved support for some existing products. The MCG1090

Magnetostrictive Level Probe, the MCG8140 Radio Level Probe, the MCG3221Modbus Interface, the MCG4200DO Relay Panel, the MCG4200AI Analog InputBoard and many more are now fully supported by the WINGauge InventoryManagement System.

MCG1500XL and MCG1500SFI SERVOS

The entire MCG1500XXX Servo Gauge product line is now supported byWINGauge. This includes display of all standard data items (level, temperature,pressure, density and BS&W), the full SFI-series remote diagnostic panel and

remote servo command and control.

SECURITY SYSTEM A complete user/group-based security system is built into WINGauge. Accesscan be controlled down to the level of the individual input field. User privilegesmay be assigned individually or in groups, and are password-protected.

7/16/2019 3900 Manual



WINFLASH

For those facilities which have L&J Technologies MCG2000SFI-seriestransmitters or MCG1600SFI radar level gauges, the WINFlash utility (a standardfeature of the WINGauge system) provides the ability to remotely configure and

re-program individual gauges.

QUICKSTART GUIDE

This section provides instruction on high-level preparation and configuration of the MCG3900. It is assumed that the user interface (menu and toolbars) is usingthe default layout, and that the loop configuration file has been properly initializedfor communication with the gauge field. Detailed information on field loop andinterface settings is available in the Administrator's Manual (supplied separately.)It is further assumed that all requisite strapping table data points have beenpreviously entered.

These specific data items will be discussed in some detail below:

1. Adding tanks into the system.

2. Set unique identifiers for each tank.

3. Set gauge address, loop and communications protocol

4. Set strapping table numbers and tank total capacity.

5. Set alarm points.

Entry of site-specific data is normally performed by L&J Technologies personnelprior to shipment, if this information is made available by the customer. This is sothe customer can place the unit into service immediately, although. It isrecommended that the customer verify all configuration information upon receiptof the system.

Starting Wingauge

After installation of the MCG3900 Wingauge program, there should be a shortcuticon on the computer desktop. Double-click on the icon with the left mousebutton. This will start the Wingauge program.

Below is an example of a typical WINGauge main display. Notice the text at the

bottom left: the current system time is displayed (it is 10:30 AM as shown) as wellas the name of the currently logged-in user. In this case the user is "ADMIN".

STATUS BAR

Fig 1- The Status Bar

The Status Bar is normally displayed at the bottom of the screen. This containsboth the Notification Area at the left (this will display the current time and thesoftware revision and site name, or it will show the name of the currently logged-in user) as well as the Loop Monitor, which is the series of numbered bulbs to theright.

The Loop Monitor will contain as many bulbs as there are configured gaugingloops, plus one additional bulb at the far right which is the Field Activity Indicator.This indicator will usually be bright green and flashing, indicating normaloperation of the system. This bulb will flash amber whenever there is there is achange in the raw data being received from the field. For example, if a level or temperature value received from a gauge is different from the value receivedfrom the previous poll of that gauge, the activity indicator will briefly flicker.

The remaining bulbs indicate the overall status of each field loop. In the exampleabove, the system is set for a maximum of five loops (as will be shown, not all of them are available.) The color and activity of each numbered bulb indicates thetype and severity of problems with field equipment on the corresponding loop.

It is important to remember these are aggregate indicators, and only show thatthere is a problem with one or more pieces of field hardware. Clicking on anybulb will immediately bring up the Field Scan Failures window for the associated

field loop. Clicking on the Field Activity bulb will bring up the Field Scan Failureswindow, only in this case it will show all field problems on all loopssimultaneously.

NO COMM (RED)

This means that the system has experienced a total loss of communication withone or more field devices. See bulb number 1 in Figure 1.

GOOD COMM (GREEN)

If a loop has operating tanks assigned, and no errors in communications are

occurring (i.e., bulb 2 above.)BAD COMM (AMBER)

This indicates that there are one or more problem gauges which are respondingto poll requests, but are returning data which is unintelligible or otherwise invalid.This can be due to misconfigured gauge hardware, defective field wiring or interface electronics, or even an incorrect gauge type setting within WINGauge.See bulb number 3 above.

7/16/2019 3900 Manual



NO GAUGES (DARK GREEN)

This means that the loop has been properly initialized and that a valid I/O portwas found, but that no tanks that have been set to use it. See bulb 4 above.

NO DEVICE (DARK GREEN "?")

Indicates that the loop has not been configured for use with a serial interfacedevice of any kind. Verify the Loop Configuration table entry for this loop. Seenumber 5 above.

PORT FAILURE (FLASHING RED)

This means that a port was assigned to the loop, but no actual interfacehardware was found (not shown in example.) Verify the Loop Configuration tableentry for this loop

SECTION 5

7/16/2019 3900 Manual


PAGE 5 – 2 SECTION 5 – DISPLAY TYPE OVERVIEW WINGAUGE v5.0 Rel.

DISPLAY TYPES

Like all Windows applications, WINGauge presents information to the user withinon-screen windows or forms. WINGauge has two basic types of such forms:static, and dynamic. Static displays are fixed in layout: the data content of a staticdisplay can change but the organization of the form will not. A good example

would be the User Authentication window, as shown below:

Fig 1 - Example of a Static display.

Obviously, the content of the Accounts listbox will change depending upon theactual user accounts available, however the basic design of the window willnever change unless the WINGauge program itself is modified. Note that therecan never be more than one instance of a Static form on-screen.

As mentioned previously, one of the more powerfull features of WINGauge V5 isthe Dynamic Forms Generator. As the name suggests, displays created by theDFG are dynamic, and both the content and layout of such forms can bemodified as desired by authorized personnel. Furthermore, multiple copies of a

Dynamic Form can be on-screen simultaneously. This is very useful for detailedmonitoring of multiple tank operations.

All dynamic displays are assembled from a fixed library of programmed datafields. For example, Product Level and Product Temperature are data fields. Theavailable data fields can be combined in different ways to produce custom forms.

All fields link directly to internal data structures within the WINGauge mainprogram. Some fields are non-editable, which means that the user cannotchange them from the keyboard. Fields such as Net Volume or Critical Time are

7/16/2019 3900 Manual



read-only fields. Others are editable, which means that the user can change their values from the keyboard. Gauge Type and Float Alarm Level are examples of editable fields.

Data fields have two components: the legend area and the data area. The legendarea simply describes the purpose of the field (e.g. Product Code or API Gravity).The data area displays the contents of the field and, in the case of editable fields,is where the user types new information.

Figure 2 below has examples of both editable and non-editable fields. Editablefields are denoted by a light background in the data area (contrast Product Levelwith Level Comm.)

There are two basic styles of Dynamic Forms: Flow and Tabular. Flow forms aretypically for data-entry forms, and for displaying information about a specific tank.Tabular forms are for displaying table-based information for multiple tanks.

Below is an example of a Flow-style display. Notice that all of the data fieldsapply to only one tank (in this case, Tank 101). The TANKS listbox at the left isused to select which tank is being viewed: when a tank is chosen, all fields will

instantly update to reflect the current status of the newly-selected tank.

Holding the mouse over the legend area of any field for a few seconds will bringup a capsule description of that field (called a tooltip.) Moving the mouse willmake the tooltip disappear.

7/16/2019 3900 Manual



Fig 2 - Example of a Flow-style Dynamic Form.

Another useful attribute of a Flow-style form (and the reason that they are calledFlow-style) is that the form can be resized, and the position of the individual fieldswill change to accommodate the new dimensions.

7/16/2019 3900 Manual



Fig 3 - Example of a Flow-style Dynamic Form after resizing.

This feature is very useful for creating custom screen layouts.

Below is an example of a Tabular Dynamic Form. Tabular Dynamic Forms canbe resized vertically, but the width of the form is fixed by the current font settingsand the number of columns.

4 AvailableStorage

Description

The volume of unused space available in the tank. This value iscalculated by taking the Total Tank Capacity entered by the enduser and subtracting the Gross Volume derived from the strappingtable for the current tank level. The value is not editable but willchange as product level moves or if Total Capacity Value changes.

Usage This is a display-only field and cannot be edited. Definition (Total Volume - Gross Volume)

... ...

15 CurrentRate

Description

This is the rate (displayed in the rate units specified on the SystemConfiguration page) at which product is flowing in or out of a tank.If the displayed number is positive, product is flowing into the tank.If the number is negative, product is leaving the tank. This number is not based upon actual flow measurements, but is derived fromthe change in product volume over time.

The volume change is calculated by the amount of level changedetected each minute and the corresponding volume changederived from the tank strapping table.

Usage This is a display-only field and cannot be edited.

Impact

An accurate current rate value is essential for the system to

calculate an accurate critical time. This allows the user to see howlong it will take to reach a high or low alarm point at the currentRate of flow. Level active/inactive and time active/inactiveparameters must be set correctly for the system to detect that atank is active.

... ...

27 GrossVolume

Description The Gross (uncorrected) Volume. The Gross Volume is determinedby indexing the current Product Level into the assigned StrappingTable for the tank. No offsets, scaling factors, or other correctionshave been applied to the volume at this point.


ImpactAccurate product level measurement as well as a properly enteredstrapping table are required for gross volume values to becalculated correctly.

48 NetVolume

Description

Net volume is calculated by taking the gross volume derived fromthe strapping table, subtracting bottom sediment and water andmultiplying the result by the correction factor. Standard APIformulas are used to calculate net volume. See SystemConfiguration page for API table selection.

Usage This is a display-only field and cannot be edited. Net Volume isdisplayed on numerous pages throughout the gauging system toallow the user quick access to current values.

# Legend Operations Where Set Access

50 ProductCode

Description The Product Code is a fifteen (15) letter designation thatindicates the type of product stored within a particular tank.

Usage

The setting of this field determines product code assigned tothe selected tank. The user cannot directly enter an arbitaryproduct code here. A list of available product codes is

presented, and the user may choose the desired code. Open any of the listed pages in the Where Set column for thisfield and select the tank whose value is to be modified. Clickon the product code field: a dropdown list of the availableproduct codes will appear. Choose the desired product codefrom the list: the system will automatically save the selectionand will continue gauging using the new product code.

Impact

The available product code list is defined by the systemadministrator in a separate data file not accessible by theuser. If a product code is not available in the pulldown list, itwill need to be added by the system administrator. Correctassignment of product codes ensures the proper generationof system reports that indicate total amounts of inventory for all products.

51 ProductLevel

Description This is the product level returned from the remote gauge. Thisvalue will be displayed in the measurement units defined for level, on the system configuration page.

Usage

This field allows for manual levels to be entered. Simply typea new level: the word MAN will appear in the Level Comm.field, and the "M" bulb will light in the Level Control field.When a manual value is entered, the system may continue topoll the remote gauge (if scan is enabled) but will ignore thereturned level value in favor of the manual one.

To return to the polled level, simply click on the "M" bulb inthe Level Control field to turn off the manual level. On thenext field update, the remote level will again be displayed.

Impact

The value in the level field has wide-ranging effects upon

other fields in the system and a number of processingfunctions. It is always desired that the system use the levelreturned from the remote gauge. This will ensure the systemis receiving current level information from the tank. Thisallows the system to check for any alarm conditions as wellas keep all volume and rate calculations current. In the eventthat a known good level cannot be obtained from the remotetransmitter, a manual level may be entered. The manual levelentry should only be temporary and it should be removed assoon as the remote transmitter is sending back a good level.

54 ProductTemp

Description This is the product temperature returned from the remotegauge. This value will be displayed in the measurementunits defined for temperature, on the system configurationpage.

Usage

This field allows for manual temperatures to be entered.Simply type a new temperature: the word MAN will appear inthe Temp Comm. field, and the "M" bulb will light in theTemp Control field. When a manual value is entered, thesystem may continue to poll the remote gauge (if scan isenabled) but will ignore the returned temperature value infavor of the manual one.

To return to the polled temperature, simply click on the "M"bulb in the Temp Control field to turn off the manualtemperature. On the next field update, the remotetemperature will again be displayed.

Impact A valid product temperature is essential for the system toaccurately calculate net volume values. A field value or manually entered value should always be present to ensureproper volume calculations.

59 Tank I.D.

Description This is the identification code that must be supplied for each and every tank in the system. This should be theactual tank number that the user is familiar with for eachtank.

Usage

The Tank I.D. for each tank must be unique: duplicate TankI.D.'s are not permitted. Up to fifteen (15) characters areallowed. Open any of the listed pages in the where setcolumn for this field and select the tank whose value is tobe modified. Either click directly on the Tank I.D. field or usethe tab key to navigate to the field. Type the new Tank I.D.value.

Impact

The Tank I.D. is the only way the system has to distinguishone tank from another: consequently everything from thescreen displays, alarm evaluation, Advance GaugingModule, and the report generator depend upon the contentsof this field. All Tank I.D.'s are configured in the system bythe system administrator. Tank I.D. should only be edited if the actual tank number has changed or if a new Tank I.D.numbering system is created.

FASTGAUGE

7/16/2019 3900 Manual



Description:

FastGauge allows up to five (5) tanks to be polled at a higher-than-normal rateusing an interleaved polling technique. The provides a more precise picture of field conditions (very useful when monitoring tanks which are in rapid motion.)When a tank is placed into FastGauge mode, all real-time displays in WINGaugewill be affected by the increased sample rate. However, depending upon the totalnumber of tanks in the system and the number of tanks in FastGauge mode,polling of other tanks may be slowed significantly. Use this option judiciously, andit is wise to deactivate FastGauge when not actually required.


Thre are three subframes to the FastGauge display. At the left is the TANKScolumn. Any tank with a checkmark to the left of it is in FastGauge mode: clickthe mouse on the corresponding checkbox to turn FastGauge on or off for thattank. Note that a maximum of five (5) tanks may be placed into FastGauge at anyone time. Attempting to use more than five is not permitted, and the system willnot accept the selection. If five tanks are already being FastGauged, in order toenable a sixth tank, one of the previous five must be turned OFF.

7/16/2019 3900 Manual



The next frame is the DATA ITEMS column. This works identically to the DATAITEMS column in the Level History and Trending displays: simply click on thedesired item to toggle it on or off. In the example shown above, the data itemsTank ID, Prod Level, Prod Temp, Avl Product, Avl Storage and Gross Vol areselected.

7/16/2019 3900 Manual




For all L&J SFI series field devices, the protocol can be set toa variety of different styles. Verify the programming of the SFITransmitter to ensure the comm. protocol is programmed asdesired.

Impact

Many gauges support multiple protocols, and valid data willnot be received if WINGauge and the gauge are configured for incompatible protocols. The correct comm. protocol will

normally be programmed by L&J prior to shipment of thesystem. It is imperative that the proper Comm. protocol beselected to match the field device protocol. If it is not,incorrect or no data at all will result for level and temperatureinformation. If the user cannot find the proper communicationprotocol in the provided list of the gauging program, theyshould consult L&J Technical support before attempting anysystem configuration.

25 GaugeAddress Description

This field is where the numeric address of the remote gaugeis entered into WINGauge. Each field device connected tosame part on the gauging system must have it's own uniquegauge address. This will allow the gauging program toidentify each tank and it's corresponding level andtemperature. Consult the users manual of the leveltransmitter in use to determine the proper procedure for setting gauge address. Whenever possibble, it is advisable toset the gauge address to match as close as possible to thetank number. For example, Tank 1 set to address 1, Tank 2 toaddress 2, etc.

Usage

Open any of the listed pages in the Where Set column for thisfield and select the tank whose value is to be modified. Either click directly upon the Gauge Address field, or use the Tabkey to navigate to the field. Type the new Gauge Addressvalue.The range of addresses that may be entered is protocol-specific. The address ranges for two of the most commonprotocols are shown in the following table:

Protocol Address Range Tankway 0 - 127

GPE 0 - 99

Attempting to enter an address that is out of the range of aparticular protocol will result in unpredictable operation andcommunications failure. Negative address numbers are notallowed.

Impact If the entered Gauge Address does not correspond to theaddress assigned to the remote gauge, no communicationcan or will take place. Even worse, the system may requestdata from the wrong tank!

40 LoopNumber

Description

This field is where the numeric Loop Number of the remotegauge is entered into WINGauge. The loop numbers will bepre-defined by L&J Engineering and the user's systemadministrator. The gauging loop is the actual communicationport in the gauging computer that the field transmitters areconnected to. A typical connection would be to use serialports Com 1 or Com 2 for example.

Usage

Open any of the listed pages in the Where Set column for thisfield and select the tank whose value is to be modified. Either click directly upon the Loop Number field, or use the Tab keyto navigate to the field. Type the new Loop Number value.

Loop Numbers can range from 1 to 32 (WINGauge supports amaximum of 32 gauging loops.) Loops correspond tophysical interface ports, and the actual assignment of a LoopNumber to a physical port is determined by the systemadministrator.

Impact

If the entered Loop Number does not correspond to aphysical communications port connected to a gauge loop, nocommunication can or will take place. It is entirely possible toset this number to a valid but incorrect loop, in which casethe system could record data from the wrong tanks.

59 Tank I.D.

Description This is the identification code that must be supplied for eachand every tank in the system. This should be the actual tanknumber that the user is familiar with for each tank.

Usage

The Tank I.D. for each tank must be unique: duplicate TankI.D.'s are not permitted. Up to fifteen (15) characters areallowed. Open any of the listed pages in the where set columnfor this field and select the tank whose value is to be

modified. Either click directly on the Tank I.D. field or use thetab key to navigate to the field. Type the new Tank I.D. value.

Impact

The Tank I.D. is the only way the system has to distinguishone tank from another: consequently everything from thescreen displays, alarm evaluation, Advance Gauging Module,and the report generator depend upon the contents of thisfield. All Tank I.D.'s are configured in the system by thesystem administrator. Tank I.D. should only be edited if theactual tank number has changed or if a new Tank I.D.numbering system is created.

GROUP DISPLAY

7/16/2019 3900 Manual



Description:

This flexible, spreadsheet-like real-time display presents detailed tankinformation, organized into arbitrary user-defined "groups". Each group maycontain information on any number of installed tanks (limited only by systemresources), and the actual data presented may be customized on a per-group

basis. Up to one hundred such groups can be created, and may be convenientlymodified or removed at any time. Tank groups are used only for the purpose of displaying numeric data, and have no effect upon data collection activities.

CREATING TANK GROUPS

This form has two operating modes: View, and Edit. The system normallydefaults to View mode when the Group Display is first loaded. If this is the firsttime the WinGauge system has been used, there will be no defined groups, sothe display will be blank. Group creation is simplicity itself: just type the desiredname into the entry field (directly above the VIEW and EDIT command buttons)and click the ADD command button. For example, click the mouse inside the

entry field and type "MY TANKS". Then click the ADD command button (or pressthe Enter key) to create a new group named "MY TANKS", which willimmediately appear in the VIEW GROUPS list box.

Notice the small selection box to the left of "MY TANKS". Single-click the box: acheckmark will appear indicating that this group has been selected for display,and the status line will change from none active to 1 active. However, as group"MY TANKS" currently has no tanks actually assigned to it, the data display willremain blank. Click the EDIT command button.

If Edit mode was successfully entered, VIEW GROUPS will change to EDIT

GROUP, as shown above, and the status line will show the name of the groupselected (in this case, "MY TANKS".) The list below the status line (which in Viewmode contains the list of groups) will now show the list of all available tank ID's.This only includes tanks that are defined as "IN USE" on the SystemConfiguration Tank Configuration tab. Use the standard checkboxes to determinewhich particular tanks should be enabled for display in this group. If checked, thecorresponding tank's information will be displayed in View mode. If leftunchecked, the data will not be displayed.

For this example, select the top two tanks for display. In the data area to theright, there should now be spreadsheet-style data display. Across the top thecolumn headers indicate the type of gauge data contained within each column:

the leftmost column indicates the physical tanks assigned to this group. The dataitems automatically selected for new groups are as follows:

Use the mouse pointer to select the new data item that should be displayed inthe selected column. The entire column will be instantly updated to reflect thechange. To blank a column, select [REMOVE]. Up to seventeen (17) columnsmay be defined at any time for a particular group, and the same data item maybe displayed in more than one column simultaneously. Each group may have itsown unique set of data items.

To complete the edit process and return to View mode, click the VIEW command

button. The display will return to viewing live data. The data area now shows thegroup name directly above the column headers: as more groups are added theycan be easily distinguished from each other. If more groups are defined than canfit in the window (a likely occurrence), standard scroll bars will appear on theright. The display is updated at regular intervals according to the MCG3900'sinternal refresh rate.

To save the current state of the Group List display, close the window using theClose gadget in the upper right hand corner of the window. If you simply exit theWinGauge program your changes will not be saved.

EDITING GROUPS

Existing tank groups may be edited in much the same manner. When in Viewmode, click on the name of the tank group to be edited, then click the EDITcommand button. Make any required modifications to the group's settings asdescribed above, then click the VIEW button to return to the live multi-groupdisplay.

Notice the two command buttons beneath the EDIT button, labeled COLORS ONand STATUS ON in the preceding example. Each group has maintains its ownsettings for these two options. COLORS ON determines whether WINGaugealarm colors will be applied to each detail line in the group display (just like the

Tank Summary shows alarm colors). The STATUS ON button chooses whether the standard communications status codes will be suffixed to the live gauge fieldsProd Level, Prod Temp and BS&W. These are the same codes that appear in thecorresponding fields in the Tank Detail and Tank Configuration pages. Whenclicked, the legend in each button will toggle to show the current setting.COLORS ON will toggle to NO COLORS, and STATUS ON will toggle to NOSTATUS.

If a particular display column has already been selected as a volume data item(i.e. Gross Vol, Net Volume, Avl Storage, and Avl Product) the pull-down listdescribed above will have three additional options in it if the column header isclicked again. They are as follows:

[SYSTEM]

Display using standard format defined on the System Configuration page.

[nnnnnnn]

Display with NO digits to the right of the decimal point.

[nnnnnnn.0].

7/16/2019 3900 Manual



Display with 1 digit to the right of the decimal point.

DELETING GROUPS

Deleting a tank group requires only two mouse clicks. Click the name of thegroup to be removed, and then click the DEL command button. A last-chance"Are you sure?" window will appear. To abort the delete and leave the groupuntouched, click the green NO button. To delete the group, click the red YESbutton, and the group will disappear without a trace. Groups thus deleted cannotbe recovered.

RENAMING GROUPS

Changing the display name of an existing group is also very straightforward.Click on the name of the group to be renamed, and type the new name into theentry field directly above the VIEW and EDIT command buttons. Click the RENbutton and the new name will be applied to the group list.

Usage


For all L&J SFI series field devices, the protocol can be set toa variety of different styles. Verify the programming of the SFITransmitter to ensure the comm. protocol is programmed as

desired.

Impact

Many gauges support multiple protocols, and valid data willnot be received if WINGauge and the gauge are configured for incompatible protocols. The correct comm. protocol willnormally be programmed by L&J prior to shipment of thesystem. It is imperative that the proper Comm. protocol beselected to match the field device protocol. If it is not,incorrect or no data at all will result for level and temperatureinformation. If the user cannot find the proper communicationprotocol in the provided list of the gauging program, theyshould consult L&J Technical support before attempting any

system configuration.

The MCG8100 page is specifically for tank installations that use one or moreModel MCG8100 remote tank interface units. This display is of no consequenceto facilities which do not use the MCG8100. This display allows the WINGaugeadministrator to download configuration information to the remote MCG8100 unit.Depending upon the current user's security privileges, write access to some or allentry fields may be restricted.

7/16/2019 3900 Manual



When the display is first invoked the TANKS list will have the focus. This listcontains the I.D.'s of all tanks within the system. Simply clicking on any tank inthe list will cause all entry fields to be instantly updated with data from the newlyselected tank. The up and down arrow keys may also be used to navigate theTank list.

The Tab key is used to move between fields. Pressing the Tab key will move thefocus highlight to the next field in the tab order: pressing Shift-Tab (hold down the

Shift and the Tab key simultaneously) will move the highlight to the previous field.

If the user attempts to modify the contents of any entry field without authorization,the User Log-In window will be automatically displayed. The same will happen if there is no active login.

When using the MCG8100, it is important that the Comm. Protocol (i.e.Communications Protocol) be set to MCG8100 for every gauge that is beingmonitored by an 8100. If this setting is incorrect, no data will be received and noconfiguration information can be transmitted.

To have WINGauge automatically transmit any configuration changes as they are

made, set the AUTOMATIC UPDATES field to YES. This is convenient when asingle changes are being made to a large number of different tanks. However, if several fields are to be modified for each tank, it is best to turn this feature off and use the manual download buttons.

The Manual Download section, shown at the bottom of the example page above,has three options, Current Tank, Current Loop and All Tanks. Pressing theCurrent Tank Transmit button will download all fields for the tank currently beingdisplayed on the MCG8100 Setup page. Pressing Current Loop Transmit willdownload configuration information for all tanks that are on the same loop as (i.e.being polled by the same MCG8100 as) the tank currently being displayed. The

All Tanks Transmit button will download data for all

tanks to all MCG8100's beingmonitored by WINGauge.

When a download button is pressed, it will change from green to amber, and willremain in that state until the download process has completed. Only one of thethree buttons may be pressed at any time for any given tank.

SERVO CONTROLLER

The Servo Controller page is for issuing remote (i.e. "GO") commands to L&JServo gauges. MCG1500XL and MCG1500SFI gauges may be operated fromthis page, provided that the gauge type has been properly set on the TankConfiguration display.

7/16/2019 3900 Manual



Fig 1 - Servo Controller

There are several regions of interest on this display, as follows:

TANKS - This is the list of currently-available Tank IDs. Simply click ONCE onany Tank ID to display live information about the tank, and to prepare to issue"GO" commands to it. Note that this page can be used to view information fromany gauge being successfully polled by WINGauge, however remote commandscan only be issued to L&J servo-type gauges.

COMMANDS

This list contains all the specific commands that can be issued to a servo. Someof these options may not be present on all systems, depending upon the type of gauge hardware in use.

GAUGE INFORMATION DISPLAY

This are encompasses a variety of information about current servo status and"GO" command processing. The large cylindrical object in the center is the TankView, which provides important data about product and BS&W levels. The lightblue area at the top indicates dead space, the bright green region denotes actualproduct, and the red-brown section depicts relative BS&W volume. Just to theright of the Tank View is the numeric status area. This shows the current state of the four level alarm points, as well as current level, temperature, BS&W anddensity readings (if available from the gauge.)

7/16/2019 3900 Manual



STATUS

The Status frame is simply a readout of several status bits that are polled fromthe remote servo gauge. Each of the seven states is OFF in the example, but if any of them were active the corresponding indicator would light. Please refer tothe User's Manual for the gauge for more information on the meaning andinterpretation of these indicators.

ACTIVITY

This is simply a log of the most recent servo "GO" commands issued to allgauges. Notice that the leftmost characters in each line of the log are the TankID, followed by the actual command that was issued to the tank. If any errors or faults occur, they will be shown in the log as well. The log is not preserved acrossa system restart.

4 AvailableStorage

Description

The volume of unused space available in the tank.

8 BS&WLevel

Description The level of water and sediment at the bottom of the tank(i.e., Bottom Sediment & Water.)

Usage

Open any of the listed pages in the Where Set column for this field and select the tank whose value is to be modified.Either click directly upon the BS&W Level field, or use theTab key to navigate to the field. Type the new BS&W Levelvalue. The value is entered in the system units chosen for Level.

This value is normally user-defined, but can be a live valuewhen using servo gauges or other devices capable of detecting the BS&W level. If a field device is used tomeasure the BS&W level, it will need to be configured on theTank Configuration page for the proper Comm. Protocol. Themost common type of L&J BS&W level measuring device isthe MCG 1500 Series Gauge which is Type 8. When this typeis selected, it will instruct the gauging program to retrievethe measured BS&W level from the MCG 1500XL SeriesGauge whenever it polls the servo for product level andtemperature.

Impact The BS&W Level value is used to determine the BS&WVolume.

Impact

The value in the level field has wide-ranging effects uponother fields in the system and a number of processingfunctions. It is always desired that the system use the levelreturned from the remote gauge. This will ensure the systemis receiving current level information from the tank. Thisallows the system to check for any alarm conditions as wellas keep all volume and rate calculations current. In the eventthat a known good level cannot be obtained from the remotetransmitter, a manual level may be entered. The manual level

entry should only be temporary and it should be removed assoon as the remote transmitter is sending back a good level.

SITE VIEW

Description:

Traditional tabular data displays efficiently deliver relevant information on largenumbers of tanks, but they do not intuitively identify the physical location of individual tanks. The SiteView module is designed to address this issue, whilesimultaneously providing real-time level and temperature updates.

7/16/2019 3900 Manual



SiteView sports a sophisticated zooming interface to customer-supplied mapimagery, and will superimpose computer generated graphics upon the mapsurface. Actual installation of map images and corresponding menu and toolbar configuration is an admistrator function that is beyond the scope of this manual.

Views may be created of different parts of a single facility, or even of entirelydifferent facilities, and may be displayed simultaneously on-screen. In theexample menu above, notice that there are "East" and "West" SiteView options,

which would depict two different regions. This is very useful when using theMultifield Integrated Gauging capabilities of the MCG3900, as data from morethan one gauging server may be combined and viewed on any client or server onthe network.


When SiteView is activated, it will attempt to display the entire map graphic withinthe confines of the available screen resolution. This makes for an excellentoverview of an entire site. Notice the circular objects that overlay each tank at thesample facility shown. Superimposed upon these "tank objects" are several textitems. At the very center is the Tank ID: the samples tanks range from Tank 1 toTank 9. Above that is the live product level value, displayed in the standardsystem units chosen for level. Below the Tank ID is the current producttemperature, also in system units. Notice that several of the tanks are display999 for temperature. This indicates that the gauge either does not supporttemperature acquisition, or that there is a communications fault. Level values willgo to above 96 feet if there is a problem with level communication. Please seethe Field Scan Failures display for further information if a problem is suspected.

In addition to the numeric readouts, the tank objects actually comprise compactbar graphs that visually display the level (on the left side of each object) andtemperature (on the right side.) The ranges are scaled to between the high-high

and low-low alarm levels specified for each tank. For example, look closely atTank 1 (the largest object, the one at the left). Notice that the level (the brightblue portion) is near the bottom of the circle, indicating that this tank is nearlyempty. On the right hand side, the bright yellow portion indicates that thetemperature is near the middle of the temperature alarm range.

Should any tanks go into an alarm state, the corresponding half of the associatedtank object will change colors to match the alarm colors used throughout the restof the program. This also includes tank motion indication (up is blue, down isgreen.) For example, if the level for Tank 2 were to exceed specified limits, theleft half of Tank 2's tank object would change color. Likewise, if the temperature

were to exceed the programmed limits, the right half of the tank object wouldchange color. This allows the operator to have an immediate overview of theentire tank farm's operational status, including the physical location of the tanks.

The window may be resized as desired, and the map image and all of the mapobjects will resize to fit. Should more detail be desired, clicking on the greenZOOM button will activate zoom mode. Left-clicking on the map, and holdingdown the button will zoom IN, right-clicking and holding will zoom the map OUT.

7/16/2019 3900 Manual



The entire map may be displayed again by clicking on the RESET button: thisdisables zoom and returns to the default settings.

If any particular tank object is too small to display the level and temperature fields(because the window has been reduced in size, or because a very large,complicated SiteView is being rendered) the system will only display the Tank IDin the center (see tanks 4 and 7 in the example.) However, by holding the mouseover any object which is not displaying numeric data, a floating tooltip will appear,

containing the live level and temperature values.

Once an alarm has been acknowledged (via the Alarm Summary screen), theassociated tank object will change to the acknowledged alarm color set. Thisindicates that, while the operator has indicated his awareness of the alarm, thecondition is still in effect. The actual color will depend upon the type of alarm(high level, hi-hi level, low level, etc.) When the system can no longer detect thealarm condition and it has been acknowledged by the operator, the backgroundcolor will return to the nominal blue and yellow, for level and temperature,respectively.

The actual alarm acknowledged alarm colors in use at a particular site may vary

depending how the system administrator has configured the system.

SOFTWARE CALIBRATION

7/16/2019 3900 Manual



Description:

The Software Calibration page permits fixed offsets to be applied to either or bothof the Level and Temperature field values. This is useful when a field device isexhibiting a known, linear error: the error can be subtracted out using SoftCal(Software Calibration. Depending upon the current user's security privileges,write access to some or all entry fields may be restricted.


The Tab key is used to move between fields. Pressing the Tab key will move thefocus highlight to the next field in the tab order: pressing Shift-Tab (hold down theShift and the Tab key simultaneously) will move the highlight to the previous field.

If the user attempts to modify the contents of any entry field without authorization,the User Log-In window will be automatically displayed. The same will happen if

there is no active login.

To create a Software Calibration offset for a specific tank, the first step is toselect the desired tank. Click on the appropriate Tank ID in the TANKS column.

Next, move to either the Level SoftCal or Temp SoftCal fields, depending uponwhich quantity is to be SoftCal'ed. In the example above, note that the ProductLevel field is reading 25-00-11 feet. Suppose that the gauge attached to Tank 1(the currently selected tank) has a known error of +21/32": this would make theactual level be exactly 26-00-00 feet. To force WINGauge to add a +21/32" offsetto all incoming level values, simply type the desired display level into the Level

SoftCal field and press the Enter key. The Level Offset field will then display thecalculated offset (in this case 00-00-21) and the Product Level fields everywherein WINGauge will be displaying the correct level of 26-00-00 feet. The sameprocedure is used to apply a temperature SoftCal.



Any WINGauge network client which is configured in READ-ONLY mode will notpermit access to any data-entry functions regardless of the user privilegesettings.

STRAPPING TABLES

Description:

The Strapping Table page is the page containing volumetric tank data. Level andvolume information is added or edited on this page with each level to volumeconversion classified as a point. These tables provide a level to volumeconversion based upon the selected engineering units and the type or configuration of the tank being gauged.

7/16/2019 3900 Manual



There are five basic styles of volumetric tables available:

• Huge Strap Table - This selection is used when there are a large number of points for greater accuracy of volume calculations. The maximumnumber of points per tank is 4000 with a maximum of 10 Huge strap tablesper system.

• Incremental Table - Used for vertical cylindrical tanks, this type table is

used when the values for volume are given as a difference from point topoint. Up to 250 points may be entered for each table with a maximum of 500 tables available.

• Strapping Table - Used for vertical cylindrical tanks, this type table isused when the values for volume are given as a cumulative value frompoint to point. All levels in between points are extrapolated in a straightline. The last point for the table would be the total volume of the tank.

Again, up to 250 points may be entered for each table with a maximum of 500 tables per system.

• Spherical Table - Used for spherical shaped tanks, the table points are

entered as cumulative volumes from point to point but the extrapolation for points in between takes into account the curvature of the tank.

• Horton Table - Used for horizontal cylindrical tanks and horizontal bullettanks with curved ends, the table points are entered as cumulativevolumes from point to point but the extrapolation for points in betweentakes into account the curvature of the horizontal cylinder as well as thecurvature of the end caps.

In general, the strapping table data is pre-defined and entered into theWINGauge program prior to delivery. However, there may be instances where

on-site modification of specific table data is required. Data should be enteredusing the proper engineering units as defined by the defaults for that particular table.


• Select Table Number - using the mouse, click on the down arrow next tothe number in the Table No. box. The drop down list allows for scrollingand clicking on the appropriate number to select a new table. Determinewhich table number is assigned to a tank by viewing the TankConfiguration page.

•

View tanks assigned to a table number by clicking on the down arrow tothe right of the number in the Tank IDs box. The drop down list shows alltanks associated with that table number.

• Assign a tank to a strapping table - see Tank Configuration page

Figure 4.

The TANK DATABASE frame is where tank control records are added to, hiddenfrom, and deleted from the WINGauge system. There are several framesavailable here, each will be described in turn:

ONLINE

This shows a list of ALL tanks that are configured for use. This does not indicatedwhether a tank is active, on scan, or that any other operating parameter hasbeen set, only that the Tank ID exists in the system and may be accessed usingthe regular system displays. A tank may be moved from the ONLINE frame to theHIDDEN frame by double-clicking upon it.

HIDDEN

This shows a list (empty, in the example) of tanks records that are available for use (and may have been configured for a specific purpose) but that are currently"hidden" from the system. WINGauge will not display or otherwise act upon anyinformation contained in a hidden record. A hidden tank may be restored toactive duty by clicking on it.

Tank records may also be completely and irrevocably removed from the system.By left-clicking on a tank in the HIDDEN frame (not the ONLINE frame) and thenright-clicking on it, the selected tank will disappear from the HIDDEN list, never to

be seen again. This is a safety feature: in order to completely remove a tank itmust first be hidden, then selected in the HIDDEN frame, and then right-clicked.

ADD TANK

One may add a tank to WINGauge by entering in the desired Tank ID (numeric or alphabetic) into the ADD TANK frame, and pressing the Enter key. The new tankwill be initialized to innocuous values, and the new ID will appear in the ONLINEframe.

1 API Gravity

Description

Gravity (weight per unit of volume) of crude oil or other liquid hydrocarbons as measured by a systemrecommended by the American Petroleum Institute.Simply enter a value into this field and the system willautomatically begin to calculate volumes based uponthe new entry. Valid API values range from -37 to 340.

Usage

Open any of the listed pages in the Where Set columnfor this field and select the tank whose value is to bemodified. Either click directly upon the API Gravityfield, or use the Tab key to navigate to the field. Typethe new API Gravity value.

Impact

The entered API Gravity affects the calculated APIcorrection factor, which in turn affects the derived NetVolume value and available product values.

NOTE: If you do not have a valid remote temperaturevalue, and/or have not entered a manual temperature,the system will automatically set the internal correctionfactor to 1 regardless of the API Table setting or thedisplayed API value. This effectively references thesystem to 60 degrees Fahrenheit, which is standard for most API calculations.

This is the BS&W Communications status field. It willcontain one or more of the following indicators:

GOOD Communication has been successfullyestablished with the remote device,and no errors have been detected.

BAD

The remote device is responding butthe response is unintelligible toWINGauge. This is most likely due tothe communications protocol beingincorrectly set for the gauge.

FAIL No response received at all. Thesystem will attempt several retriesautomatically before indicating failure.

OFF Field scan has been turned off. Nopolling of the gauge is occurring or isbeing attempted.

The level being displayed was enteredmanually by the user. The system maystill be polling the gauge (dependingupon the settings in the Level Controlfield) but the returned Product Leveldata is being discarded.

ERR A undetermined error has occurred.Please report this to L&J Technicalsupport.

BS&W Comm. refers to the status of fieldcommunication to devices that measure the BS&Wlevel in the storage tanks. There are a number of devices that automatically communicate the BS&Wlevel back to the gauging program. Instantaneousstatus of field comm. from the remote BS&Wmeasuring devices is shown in this data field. If thereis no field device in use to measure BS&W, the BS&Wlevel can be manually measured by the end user andentered into the BS&W level field. When this is done,the "MAN" indicator will be displayed for BS&W Comm.status indicating that the value is manually entered.

14 CriticalTime

Description

Given that a tank is in motion and that a flow rate hasbeen detected, Critical Time is defined as the timeremaining for the product level to reach the high alarmlevel (if the tank is filling) or the low alarm level (if thetank is emptying.) The software automaticallydetermines the correct level to use from the directionof flow.

The calculated value for Critical Time is based uponthe current flow rate, current gross volume, and theprogrammed alarm level (after conversion to thecorresponding volume.) During each update cycle, thedifference between the current volume and theapplicable alarm volume is divided by the flow rate togive Critical Time. Critical Time is viewed on-screen ashours and minutes (hhh:mm). It appears as a data fieldon Tank Detail page (see example below), theFastGauge display, and as a user-selectable columnoption in the Tank Groups display. It is also availableas a display field in the Dynamic Forms Generator.

In all cases, if a tank is not in motion (no level change)and/or the flow rate is zero, the symbol "N/A" (NotAvailable) will appear instead of a Critical Time value.The target values for Critical Time are specified here,via the High High, Hi-Hi, Low and Low-Low level alarm

set points.

In this example, the High Level set point (7.106 meters)corresponds to 4000 barrels of product in thisparticular tank. Likewise, the Low Level value of 3.549meters indicates a volume of 2000 barrels of product.When the Critical Time displays as zero, one of theselevels has been reached. The Critical Time value shownin the preceding example is ten hours, zero minutes.This number was determined via the following simplecalculation: Gross Volume = 3000 barrels Flow Rate =100 barrels per hour High Alarm = 7.106 meters or 4000barrels. Critical Time = (4000 - 3000) / 100, or 10 hours.


Impact Allows user instant access to time remaining beforehigh or low alarm limits is exceeded, based upon the

current flow rate.

... ...

15 CurrentRate

Description

This is the rate (displayed in the rate units specified onthe System Configuration page) at which product isflowing in or out of a tank. If the displayed number ispositive, product is flowing into the tank. If the number is negative, product is leaving the tank. This number isnot based upon actual flow measurements, but isderived from the change in product volume over time.

The volume change is calculated by the amount of level change detected each minute and thecorresponding volume change derived from the tankstrapping table.


Impact

An accurate current rate value is essential for thesystem to calculate an accurate critical time. Thisallows the user to see how long it will take to reach ahigh or low alarm point at the current Rate of flow.Level active/inactive and time active/inactiveparameters must be set correctly for the system todetect that a tank is active.

The MCG3900 supports discrete inputs as used on theMCG2000 and MCG2000-SFI series of gauges, as wellas some older GPE products.

The appropriate Enable field must be set to YES on theTank Configuration page in order for the discreteinputs to be functional. If a Discrete Input is enabled,and it's state transitions from HIGH to LOW, a DiscreteAlarm will be logged to the Alarm Summary and AlarmHistory pages, and an Emergency class alarm will begenerated.

See the section on the Enable fields above.

Usage

These are display-only fields and cannot be edited.User can wire in dry contact switches into the discreteinputs on the MCG2000 series transmitter and thestatus of the switches will be transmitted back to thegauging computer. This will allow monitoring of theswitches through the tank gauging software. Thestatus of the switches will only be shown as OPEN or CLOSE for the input status. The system will generate adiscrete input alarm when the input changes fromclose to open.

Impact

Any type of dry contact switch can be wired into thediscrete inputs on a MCG2000 series level transmitter.When the switch opens on the discrete input, thegauging system will display a Discrete input alarm. It isimportant for all operators of the system to be madeaware of exactly what is connected to the discreteinput so appropriate action can be taken in the event of a Discrete alarm.

35 LevelActive

Description

The Level Active field works in conjunction with theTime Active field to determine whether a tank isACTIVE or INACTIVE. An active tank is one that is inmotion (i.e., experiencing a change in level.) Aninactive tank is one whose level is not changing.

In order for a tank to switch from the inactive state tothe active state, the level must change more than the

specified Level Active field within the specified TimeActive interval. For example: If the level active field isset to 5 and the time active field is set to 2, the systemwill consider the level active if the product levelchanges 5 or more sixteenths of an inch in 2 minutes.The tank will remain active as long as the levelcontinues to change at least 5 sixteenths every 2minutes. Level active parameters work the samewhether the tank level is going up or down.

Usage

Open any of the listed pages in the Where Set columnfor this field and select the tank whose value is to bemodified. Either click directly upon the Level Activefield, or use the Tab key to navigate to the field. Typethe new Level Active value. The value is entered in16ths of an inch.


Impact

The Level Active field affects all aspects of theprogram where tank activity is important.

MAN

The level being displayed was enteredmanually by the user. The system maystill be polling the gauge (dependingupon the settings in the Level Controlfield) but the returned Product Leveldata is being discarded.

UF This gauge has a SoftCal (SoftwareCalibration) applied, and an UnderFlowcondition has occurred.

CAL

A SoftCal has been applied, and theProduct Level is being offset by thespecified amount. This is not an error condition: it simply indicates thepresence of a SoftCal offset.

AMB

MCG200SFI-only: An Ambiguity Error has occurred. This condition occurswhen the gauge has detected anexcessive change in level. Thistypically happens when the encoder wheel's emitter or receiver hasmalfunctioned, or there is some other problem with the optics.

CA

MCG200SFI-only: A Cable Fault hasbeen detected. This indicates that thereis virtually no emitter current (generallythis occurs when the cable leadingfrom the internal circuit board to theencoded module has been unplugged.)

ECL MCG200SFI-only: The emitter currenthas dropped below the factory-programmed minimum value.

ECH MCG200SFI-only: The emitter currenthas exceeded the factory-programmedmaximum value.


These values will give the user immediate status of every level transmitting device connected to the tankgauging system.

A Alarm Evaluation

M Manual Entry

C Software Calibration (SoftCal)

When the bulb is lit, the function is enabled. When thebulb is dark, the function is disabled.

Usage

Open any of the listed pages in the Where Set columnfor this field and select the tank whose value is to bemodified. Click on (S)can bulb to toggle Level scanningon and off, click on the (A) bulb to turn AlarmEvaluation on or off, click on the (M) bulb to turnManual Entry mode on or off, or click on the "C" bulbto turn Software Calibration on or off. When the scan

bulb is lit, the gauging program will send out requeststo the level transmitter requesting it to send back level.The program will continuously send requests to thetank as long as the scan bulb is lit. If the scan bulb isnot lit, the gauging program will not send requests tothe level transmitter.

When the Alarm Evaluation bulb is lit, the system willprocess any level, temperature, rate, etc. alarms thatoccur for the tank. This includes opening the alarmsummary window as well as sounding the audiblealarm for any new alarms encountered. If the alarmevaluation bulb is not lit, the system will not processany alarm conditions that occur for the tank. The alarmcondition will be ignored by the system and no visualor audible indicators for the alarm condition will occur.If the manual entry bulb is lit, this indicates thedisplayed level was entered from the keyboard

manually and is not a level from a field transmitter. Thesystem will use this manually entered value for allcalculations for the tank. If the manual entry bulb is notlit, this indicates that the sytem will try to interogate afield transmitter for level provided that the scan bulb islit.

If the Software Calibration bulb is lit, this indicated thatthe displayed level has been offset by the user to reada level other than that received from the leveltransmitter.

If the transmitter is sending a level to the gaugingsystem of 12 feet 6 inches, but the user has determinedthat the actual level in the tank is 12 feet 3 inches, theSoft Calibration function can be used to make the levelread 12 feet 3 inches. This offset will be used for the

tank as long as the Software Calibration button is lit.

Impact

If Level scanning is disabled, the system will notattempt to acquire updated Level values from theremote gauge, and the Product Level and variousproduct volume fields will reflect the last known gooddata. If level scan is disabled and the last known levelis not a good value, a manual entry should be used for product level. If level scan and manual entry areenabled at the same time, the manually entered levelwill be used by the system. The gauging system willstill scan the tank for product level but the returnedlevel will not be used until the manual entry is disabled.

14 CriticalTime

Description

Given that a tank is in motion and that a flow rate hasbeen detected, Critical Time is defined as the timeremaining for the product level to reach the highalarm level (if the tank is filling) or the low alarm level

(if the tank is emptying.) The software automaticallydetermines the correct level to use from the directionof flow.

The calculated value for Critical Time is based uponthe current flow rate, current gross volume, and theprogrammed alarm level (after conversion to thecorresponding volume.) During each update cycle,the difference between the current volume and theapplicable alarm volume is divided by the flow rate togive Critical Time. Critical Time is viewed on-screenas hours and minutes (hhh:mm). It appears as a datafield on Tank Detail page (see example below), theFastGauge display, and as a user-selectable columnoption in the Tank Groups display. It is also availableas a display field in the Dynamic Forms Generator.

In all cases, if a tank is not in motion (no level

change) and/or the flow rate is zero, the symbol "N/A"(Not Available) will appear instead of a Critical Timevalue. The target values for Critical Time arespecified here, via the High High, Hi-Hi, Low and Low-Low level alarm set points.

In this example, the High Level set point (7.106meters) corresponds to 4000 barrels of product inthis particular tank. Likewise, the Low Level value of 3.549 meters indicates a volume of 2000 barrels of product. When the Critical Time displays as zero, oneof these levels has been reached. The Critical Timevalue shown in the preceding example is ten hours,zero minutes. This number was determined via thefollowing simple calculation: Gross Volume = 3000barrels Flow Rate = 100 barrels per hour High Alarm =7.106 meters or 4000 barrels. Critical Time = (4000 -

3000) / 100, or 10 hours.


Impact Allows user instant access to time remaining beforehigh or low alarm limits is exceeded, based upon thecurrent flow rate.

15 CurrentRate

Description

This is the rate (displayed in the rate units specifiedon the System Configuration page) at which productis flowing in or out of a tank. If the displayed number is positive, product is flowing into the tank. If thenumber is negative, product is leaving the tank. Thisnumber is not based upon actual flow measurements,but is derived from the change in product volumeover time.



Impact

An accurate current rate value is essential for thesystem to calculate an accurate critical time. Thisallows the user to see how long it will take to reach ahigh or low alarm point at the current Rate of flow.Level active/inactive and time active/inactiveparameters must be set correctly for the system to

This general-purpose alarm is typically used by anoperator as a reminder when a tank which is inmotion has reached a desired level. Simply enter thedesired target level (which should be above thecurrent level if the tank is filling, or below the currentlevel if the tank is emptying.) When the current levelequals or exceeds the programmed Float Alarm level,an alarm sound will be generated and the AlarmSummary page will be displayed automatically.

Usage

Open any of the listed pages in the Where Set columnfor this field and select the tank whose value is to bemodified. Either click directly upon the Float Alarmfield, or use the Tab key to navigate to the field. Typethe new Float Alarm level value. The value is enteredin the system units chosen for Level.


Impact

If the Float Alarm is enabled (a non-zero value hasbeen entered) the Critical Time field will reflect thecalculated time remaining until the Float Alarm level

will be reached.

If the Float Alarm is disabled (a zero value has beenentered) the Critical Time field will reflect the timeremaining until the next standard alarm level value isreached. The system will automatically select theproper alarm level to check based upon the currentlevel and tank movement direction. For moreinformation see the Critical Time field descriptionabove.

Input 1(discrete)

Input 2(discrete)

Description


Code Function



The MCG3900 supports discrete inputs as used onthe MCG2000 and MCG2000-SFI series of gauges, aswell as some older GPE products.

The appropriate Enable field must be set to YES on

the Tank Configuration page in order for the discreteinputs to be functional. If a Discrete Input is enabled,and it's state transitions from HIGH to LOW, aDiscrete Alarm will be logged to the Alarm Summaryand Alarm History pages, and an Emergency class alarm will be generated.


Usage

These are display-only fields and cannot be edited.User can wire in dry contact switches into thediscrete inputs on the MCG2000 series transmitter and the status of the switches will be transmittedback to the gauging computer. This will allowmonitoring of the switches through the tank gaugingsoftware. The status of the switches will only beshown as OPEN or CLOSE for the input status. The

system will generate a discrete input alarm when theinput changes from close to open.

Impact

Any type of dry contact switch can be wired into thediscrete inputs on a MCG2000 series leveltransmitter. When the switch opens on the discreteinput, the gauging system will display a Discreteinput alarm. It is important for all operators of thesystem to be made aware of exactly what isconnected to the discrete input so appropriate actioncan be taken in the event of a Discrete alarm.

37 LevelControl

Description

The Level Control field allows the user to toggle thefollowing real-time gauging parameters. There arefour small light bulbs in this field, each containing aletter code corresponding to the function the bulbcontrols, as follows:

Code Function

S Scan

A Alarm Evaluation

M Manual Entry



Usage

Open any of the listed pages in the Where Set columnfor this field and select the tank whose value is to bemodified. Click on (S)can bulb to toggle Levelscanning on and off, click on the (A) bulb to turnAlarm Evaluation on or off, click on the (M) bulb toturn Manual Entry mode on or off, or click on the "C"bulb to turn Software Calibration on or off. When thescan bulb is lit, the gauging program will send outrequests to the level transmitter requesting it to sendback level. The program will continuously sendrequests to the tank as long as the scan bulb is lit. If the scan bulb is not lit, the gauging program will not

send requests to the level transmitter.

When the Alarm Evaluation bulb is lit, the system willprocess any level, temperature, rate, etc. alarms thatoccur for the tank. This includes opening the alarmsummary window as well as sounding the audible

alarm for any new alarms encountered. If the alarmevaluation bulb is not lit, the system will not processany alarm conditions that occur for the tank. Thealarm condition will be ignored by the system and novisual or audible indicators for the alarm conditionwill occur. If the manual entry bulb is lit, thisindicates the displayed level was entered from thekeyboard manually and is not a level from a fieldtransmitter. The system will use this manuallyentered value for all calculations for the tank. If themanual entry bulb is not lit, this indicates that thesytem will try to interogate a field transmitter for level

provided that the scan bulb is lit.

If the Software Calibration bulb is lit, this indicatedthat the displayed level has been offset by the user toread a level other than that received from the leveltransmitter.

If the transmitter is sending a level to the gaugingsystem of 12 feet 6 inches, but the user hasdetermined that the actual level in the tank is 12 feet3 inches, the Soft Calibration function can be used tomake the level read 12 feet 3 inches. This offset willbe used for the tank as long as the SoftwareCalibration button is lit.

58 TankControl

Description This field allows all field scan and alarm evaluationsettings for the selected tank to be enabled or disabled simultaneously.

Usage

The Tank Control field allows the user to toggle thefollowing real-time gauging parameters. There aretwo small light bulbs in this field, each containing aletter code corresponding to the function the bulbcontrols, as follows:

Code Function S Master Scan


This field works similarly to the other Control fields,however it does not control a specific data item:rather, it controls whether or not the other itemsperform their functions. For example, if the Master Scan bulb is dark (disabled) none of the other gaugepolling functions will work (level, temp, BS&W,Density, etc.) This allows a gauge to be totallydeactivated with a single mouse click.

Impact

This setting will potentially stop all scanning of aselected tank for level, temp, etc. Even if level andtemp scan are enabled in their respective fields, thetank control field will still stop the system frompolling the remote transmitter. All alarm evaluationcan be disabled for a tank from the tank Control field.If this is selected, the system will ignore all alarmconditions that may occur and no visual or audiblewarnings will be present in the system.

TANK TRANSFERS

Figure 1.

The Introduction provides some basic instructions on using the Tank Transfersdisplay, but more importantly provides a menu to all the different display panels.

7/16/2019 3900 Manual



Simply click on the desired item in the OPTIONS frame to bring up either of thefollowing two panels.

Figure 2.

The CREATE/MANAGE panel is where tank transfers are initialized, created,paused, stopped and deleted. There is a fair amount of detail on this page, andall the options will be discussed below.

The first step in creating a transfer is to select the tanks that will be involved inthe transfer. This is done via the "FROM" TANK and "TO" TANK frames. Simplyselect a tank from each frame (tanks 1 and 7 in the example.)

The next step is to select one or more terminating conditions for the transfer.There are several such conditions that can be configured in the TRANSFERPARAMETERS frame. Tanks can be monitored for the volume in the tank, theactual volume transferred, a specific ending time and date, or a set number of running hours. These can be used in any combination, and the first condition tobe met will end the transfer.

For example, how would one create a transfer from tank 3 to 5, that is to run untileither the volume in tank 3 reaches 30,000 units -or- the transfer has run for three hours?

1. Click on #3 in the "FROM" TANK frame.

2. Click on #5 in the "TO" TANK frame.

Enter 30000 into the TRANSFER PARAMETERS frame, into the "FROM"TANKS's TANK field. Make sure that the green TANK button is lit.

3. Enter 03 00 into the RUN TIME fields.

4. Click on the CREATE TRANSFER button.

7/16/2019 3900 Manual



At this point, if everything has been entered correctly, the transfer will beassigned an ID number and will appear in the TRANSFER STATUS frame. After a few seconds, the code RDY will appear next to the ID number. Note that thetransfer is not yet running: it has merely been allocated. To actually start thetransfer, click on the transfer's entry in the TRANSFER STATUS frame, and thenclick on the START button just below it. After a short delay, the word RUN willreplace the RDY code from the previous step. At this point, the transfer isrunning.

Transfers may be paused by selecting a running transfer from the TRANSFERSTATUS frame and then clicking on the PAUSE button below. The word RUNwill be replaced with PAU. This indicates that the system is no longer monitoringthe transfer for completion, but will resume operations when the CONTINUEbutton is pressed. This is useful if a transfer must be interrupted for any reasonbut it is not desired to create a new transfer.

Transfers may be stopped (i.e. premature termination) with the STOP button, andmay be completely removed via the DELETE button. NOTE: A transfer cannot bedeleted unless it has terminated normally or has been manually stopped first, byclicking the STOP button.

TANK TRENDING

During normal operation of the gauging system, live data values, derivedvolumetric information and specific configuration items are stored in a database.The Tank Trending display allows the operator to review the past twenty-four hours of data accumulated by this database in graphical form. The numericvalues that were acquired at any desired time may be determined via a mouse-driven cursor (the vertical green bar in the Trending Display area.)

Fig 1 - Tank Trending

There are three distinct functional areas to this display. To the left is the TANKSselection list: this will show a complete list of all unique tanks that are stored inthe database. If the Tank I.D. assigned to any tank is changed (using either theTank Configuration or Tank Detail screens) both the new I.D. and the original onewill be displayed in the Tanks list. This allows data for a renamed tank tocontinue to be available for viewing.

The Data Select list determines the specific data items that are to be viewed. InFigure 1, only the ProdLevel item is selected (notice that the ProdLevel entry inthe Data Select list is highlighted.) Simply clicking on an item will toggle its stateon or off: if an item is on, it will be highlighted, if it is off , it will be dimmed. In theexample below, the AvlStorage (available storage) and AvlProduct (availableproduct) items have been selected, in addition to ProdLevel. Each item has adifferent color-code: this is important because information presented in theTrending Display area is keyed to these colors.

7/16/2019 3900 Manual



Fig 2- Tank Trending for multiple items.

The large region at the right is the main Trending Display. This window hasseveral important aspects. The background grid is broken into twenty-four segments horizontally, corresponding to twenty-four hours of graphicalinformation: the vertical axis is broken into ten segments to provide a relativeindication of magnitude. The most recently-acquired data is at the right of thedisplay, with the data becoming one hour older with each successive grid intervalto the left. Each Items selected in the Data Select area will have a correspondingwaveform displayed in the Trending Display, and as mentioned above thewaveform will be keyed to the color of the selected item. In the example, the

AvlProduct item is active, and is shown in bright cyan: the matching sample AvlProduct graph is shown at the bottom third of the Trending Display in thesame color. The other active data items are also shown in matching colors.

However, this graphical presentation would not be very useful without some wayto determine the numerical values that were recorded at specific times. This is

accomplished via the selection cursor. Simply move the mouse pointer over theTrending Display: the green vertical bar seen in both examples will follow thehorizontal position of the mouse pointer within the Trending Display area. Assoon as the mouse leaves the Trending Display, the cursor will disappear automatically.

The block of numbers at the far right of the screen are continually updated toreflect the data values that existed at whatever point in time the green selectioncursor is located. The top two fields (shown in white) are the time and date stampfrom the database record pointed to by the cursor (given as 24-hour militarytime.) The remaining fields are color-coded to match the corresponding

highlighted items in the Data Select list. In Figure 1, the selection cursor is almostdirectly in the center of the Trending Display. The recorded date is March 16,2003, the time is twenty-two minutes past 11:00 PM, the level at the cursor is 14-06-27, the available storage is 615,368.0, and the available product is 105,144.0.No units are given here, as the units are the same as all other displays, and areset using the System Configuration page.

Description The level of water and sediment at the bottom of the tank(i.e., Bottom Sediment & Water.)

Usage

Open any of the listed pages in the Where Set column for this field and select the tank whose value is to be modified.Either click directly upon the BS&W Level field, or use theTab key to navigate to the field. Type the new BS&W Levelvalue. The value is entered in the system units chosen for Level.

This value is normally user-defined, but can be a live valuewhen using servo gauges or other devices capable of detecting the BS&W level. If a field device is used tomeasure the BS&W level, it will need to be configured on theTank Configuration page for the proper Comm. Protocol. Themost common type of L&J BS&W level measuring device is

the MCG 1500 Series Gauge which is Type 8. When this typeis selected, it will instruct the gauging program to retrievethe measured BS&W level from the MCG 1500XL SeriesGauge whenever it polls the servo for product level andtemperature.

15 CurrentRate

Description

This is the rate (displayed in the rate units specified on theSystem Configuration page) at which product is flowing in or out of a tank. If the displayed number is positive, product isflowing into the tank. If the number is negative, product isleaving the tank. This number is not based upon actual flowmeasurements, but is derived from the change in productvolume over time.

The volume change is calculated by the amount of levelchange detected each minute and the corresponding volumechange derived from the tank strapping table.


Impact

An accurate current rate value is essential for the system tocalculate an accurate critical time. This allows the user tosee how long it will take to reach a high or low alarm point atthe current Rate of flow. Level active/inactive and timeactive/inactive parameters must be set correctly for thesystem to detect that a tank is active.

19 Density

Description Product density, displayed in the system units specified for Density.. For transmitters that do not return this data, amanual entry must be provided. Alarm evaluation is notavailable for Density.

Usage Open any of the listed pages in the Where Set column for this field and select the tank whose value is to be modified.Either click directly upon the Density field, or use the Tabkey to navigate to the field. Type the new Density value.

Impact

The entered Density affects the calculated API correctionfactor, which in turn affects the derived Net Volume value.

NOTE: If you do not have a valid remote temperature value,and/or have not entered a manual temperature, the systemwill automatically set the internal correction factor to 1regardless of the API Table setting or the displayed APIvalue. This effectively references the system to 60 degreesFahrenheit, which is standard for most API calculations.

14 CriticalTime

Description

Given that a tank is in motion and that a flow rate has beendetected, Critical Time is defined as the time remaining for the product level to reach the high alarm level (if the tank isfilling) or the low alarm level (if the tank is emptying.) Thesoftware automatically determines the correct level to usefrom the direction of flow.

The calculated value for Critical Time is based upon thecurrent flow rate, current gross volume, and theprogrammed alarm level (after conversion to thecorresponding volume.) During each update cycle, thedifference between the current volume and the applicablealarm volume is divided by the flow rate to give CriticalTime. Critical Time is viewed on-screen as hours andminutes (hhh:mm). It appears as a data field on Tank Detailpage (see example below), the FastGauge display, and as auser-selectable column option in the Tank Groups display.It is also available as a display field in the Dynamic Forms

Generator.

In all cases, if a tank is not in motion (no level change)and/or the flow rate is zero, the symbol "N/A" (NotAvailable) will appear instead of a Critical Time value. Thetarget values for Critical Time are specified here, via theHigh High, Hi-Hi, Low and Low-Low level alarm set points.

In this example, the High Level set point (7.106 meters)corresponds to 4000 barrels of product in this particular tank. Likewise, the Low Level value of 3.549 metersindicates a volume of 2000 barrels of product. When theCritical Time displays as zero, one of these levels has beenreached. The Critical Time value shown in the preceding

example is ten hours, zero minutes. This number wasdetermined via the following simple calculation: GrossVolume = 3000 barrels Flow Rate = 100 barrels per hour High Alarm = 7.106 meters or 4000 barrels. Critical Time =(4000 - 3000) / 100, or 10 hours.

SYSTEM DATA FIELDS

INTRODUCTION

WINGauge processes some sixty-odd numeric and textual data fields, some of which are supplied by the end user, andothers that are entirely computer-generated. This section documents, in some detail, the workings of these various fieldsand how they interact with each other.

On-screen access to the various user-modifiable data fields is controlled by the WINGauge security system. By default,WINGauge ships with three different user groups: Administrator, Supervisor and Operator. Users assigned to each of thesethree groups typically have differing access privileges. This means that an individual assigned to the Operator group, for

example, may not be able to modify the contents of data fields that a Supervisor or an Administrator could. The last columnon the right, Access, describes the minimum security level required to modify the corresponding data field. This is intendedto protect against unintentional or unauthorized modification of system configuration data. Actual assignment of individualusers to specific groups is the customer's responsibility.

CAVEATS

Fields which are read-only (i.e., not modifiable by the user under any conditions) are marked with a circumflex, "...".

All numeric quantities (e.g., Level, Temperature, Volume and so forth) are assumed to be displayed using the appropriatemeasurement units selected on the System Configuration page, unless otherwise noted. The Usage sections of eachdescription also assume that a user with an appropriate security level has already logged in: if this is not the case, anyattempt to modify a data field will fail, and will immediately bring up the User Login screen.

There is no explicit "save" function. All authorized modifications to data fields are immediately and automatically saved by

the system.

The user groups referenced in the Access column refer to the default shipping configuration of WINGauge: the local systemAdministrator may create additional groups.

ALARM CLASSES

The MCG3900 has three (3) alarm categories or classes. Each class is distinguished by a different sound that is generatedwhen the alarm occurs: this capability is only available to multimedia-equipped computer systems with attached speakers.Systems using the relay alarm output of the MCG3281 Slimline FIC, for example, only have a single control output and thuseffectively only have a single alarm class.

The three classes are organized by increasing severity, as shown below:

Class Description Used ByOperational Non-critical utility alarm.. Float Alarm

Warning Non-critical warning alarm. Flow Rate, High Level, Low Level Emergency Critical alarm! HiHi Level, LoLo Level, Dead Tank, Discrete Inputs (incl. MCG3281)

Operational and Warning alarms are generally non-critical, but do indicate a condition for which the system was specificallyinstructed to monitor. The Emergency alarms indicate that a critical malfunction or other condition has or is about to occur,and that remedial action should be taken IMMEDIATELY!

IMPORTANT

The appropriateness of generated alarms is entirely dependent upon system configuration values entered by the customer.If, for example, a HiHi Alarm Level were entered that was above a tank's actual safe fill level, a tank overflow condition couldoccur, and no alarms would be generated.

In addition, alarms will only occur if both field scan and alarm evaluation are enabled for the quantity being monitored. For example, in order for a temperature alarm to be generated, the Tank Control field must have both the (S)can and (A)larmEvaluation bulbs lit and the Temp Control field must also have them lit. If a manual level has been entered for Temperature,the system will evaluate the manual value not the field value!

DATA FIELDS

The following table describes all of the numeric and textual data items that are used throughout the WINGauge gaugingsystem. The Legend column references the text used to refer to each field on the various WINGauge screens. The Operations column provides detailed information on the content of each data field, how it is used, and how it interacts with related datafields. Where Set indicates the pages where the field can be modified.

STANDARD DATA FIELDS


1 APIGravity

Description

Gravity (weight per unit of volume) of crude oil or other liquid hydrocarbons as measured by a systemrecommended by the American Petroleum Institute.Simply enter a value into this field and the system willautomatically begin to calculate volumes based uponthe new entry. Valid API values range from -37 to 340.

Usage


Impact

The entered API Gravity affects the calculated APIcorrection factor, which in turn affects the derivedNet Volume value and available product values.

NOTE: If you do not have a valid remote temperaturevalue, and/or have not entered a manual temperature,the system will automatically set the internalcorrection factor to 1 regardless of the API Tablesetting or the displayed API value. This effectivelyreferences the system to 60 degrees Fahrenheit,which is standard for most API calculations.

2 API Table

Description

The API Table setting instructs the system to use aspecific internal data table to calculate a volumecorrection factor. These tables are standard tables asdefined by the American Petroleum Institute. Note: If a tank has API Table set to AUTO, the systemanalyzes the system engineering units and choosesthe appropriate API Table (54A,B,C for Metric units,6A,B,C for non-metric units).The following are thecurrently available API table settings:

AUTO 24B

6A 6

6B 54A

6C 54B

24 54C

24A 34

Usage

Open any of the listed pages in the Where Set columnfor this field and select the tank whose value is to bemodified. Click on the API Table field: a dropdown listof the available API tables will appear. Choose thedesired table from the list: the system willautomatically save the selection and will continuegauging using the new table.

Impact The choice of API table affects the calculated APIcorrection factor, which in turn affects the derived

Net Volume value and available product.


3 AvailableProduct

Description

The volume of product actually available from thetank. This value is calculated by taking the bottomvalue entered by the end user and subtracting it from

the Net Volume. This value is not editable by the enduser, but proper temperature and gravity values arerequired for the system to accurately derive NetVolume. This value is automatically updated by thesystem whenever any measured or entered valueschange.



... ...

4 AvailableStorage

Description

The volume of unused space available in the tank.This value is calculated by taking the Total TankCapacity entered by the end user and subtracting theGross Volume derived from the strapping table for the current tank level. The value is not editable butwill change as product level moves or if TotalCapacity Value changes.


... ...

7/16/2019 3900 Manual




5 BottomVolume

Description The volume at the bottom of the tank that is normallynot available. This will normally be the product levelbelow the suction line connected to the tank whichthe pump cannot access.

Usage

Open any of the listed pages in the Where Set columnfor this field and select the tank whose value is to bemodified. Either click directly upon the BottomVolume field, or use the Tab key to navigate to the

field. Type the new Bottom Volume value. The valueis entered in the system units chosen for Volume.



6 BS&WComm.

Description



BAD




MAN

The level being displayed wasentered manually by the user. Thesystem may still be polling the gauge(depending upon the settings in theLevel Control field) but the returnedProduct Level data is beingdiscarded.


BS&W Comm. refers to the status of fieldcommunication to devices that measure the BS&Wlevel in the storage tanks. There are a number of devices that automatically communicate the BS&Wlevel back to the gauging program. Instantaneousstatus of field comm. from the remote BS&Wmeasuring devices is shown in this data field. If thereis no field device in use to measure BS&W, the BS&Wlevel can be manually measured by the end user andentered into the BS&W level field. When this is done,the "MAN" indicator will be displayed for BS&WComm. status indicating that the value is manuallyentered.

7 BS&WControl

Description

The BS&W Control field allows the user to toggle thefollowing real-time gauging parameters. There aretwo small light bulbs in this field, each containing aletter code corresponding to the function the bulbcontrols, as follows:

Code Function S Scan

M Manual Entry


Usage

Open any of the listed pages in the Where Set columnfor this field and select the tank whose value is to bemodified. Click on (S)can bulb to toggle BS&Wscanning on and off, or click on the (M) bulb to turnManual Entry mode on or off.

Impact

If BS&W scanning is disabled, the system will notattempt to acquire updated BS&W values from theremote gauge, and the BS&W Level and BS&WVolume fields, will reflect the last known good fielddata. If these field values are incorrect, a manualentry for BS&W should be entered to allow thesystem to have a good BS&W Value.

8 BS&WLevel

Description The level of water and sediment at the bottom of thetank (i.e., Bottom Sediment & Water.)

Usage

Open any of the listed pages in the Where Set columnfor this field and select the tank whose value is to bemodified. Either click directly upon the BS&W Levelfield, or use the Tab key to navigate to the field. Typethe new BS&W Level value. The value is entered inthe system units chosen for Level.

This value is normally user-defined, but can be a livevalue when using servo gauges or other devicescapable of detecting the BS&W level. If a field deviceis used to measure the BS&W level, it will need to beconfigured on the Tank Configuration page for theproper Comm. Protocol. The most common type of L&J BS&W level measuring device is the MCG 1500Series Gauge which is Type 8. When this type isselected, it will instruct the gauging program to

retrieve the measured BS&W level from the MCG1500XL Series Gauge whenever it polls the servo for product level and temperature.

Impact The BS&W Level value is used to determine theBS&W Volume.

Super

7/16/2019 3900 Manual




9 BS&WVolume

Description

The volume of water and sediment at the bottom of the tank. Derived from the BS&W Level field. TheBS&W level value is located in the strapping tableassigned to the tank and the volume is extracted for the corresponding level.

Usage

The BS&W Volume is used to calculate the NetVolume of the tank. See Net Volume. It is importantthat all BS&W level fields be set to zero if tanks

contain no BS&W. The value entered into this fieldwill persist if BS&W Level Scan is OFF and BS&WLevel Manual is OFF. If either BS&W Level Scan isON, or BS&W Level Manual is ON, then the BS&WVolume is derived from the BS&W Level field via theusual strapping table lookup logic.

7/16/2019 3900 Manual





The setting of this field determines thecommunications protocol to be used with the gaugeattached to the selected tank. Note: when usingWINGauge with the L&J MCG2000SFI gauge, thesystem can monitor the gauge for advanceddiagnostic information (see the Level Comm fielddefinition below.) However, the system must be

configured for one of the MCG2000SFI protocols.Number 7 in the list below (MCG2000SF-CRC) is therecommended setting for use with MCG2000SFIgauges. The following is a list of available protocols:

1 MCG32NDS Standard L&J 32ndscomm.

7/16/2019 3900 Manual




Usage

Open any of the listed pages in the Where Set columnfor this field and select the tank whose value is to bemodified. Click on the Comm Protocol field: adropdown list of the available protocols will appear.Choose the desired protocol from the list: the systemwill automatically save the selection and will continuegauging using the new protocol. Note that theupdated selection will not take effect until the

Advanced Gauging Module has completed polling onthe affected loop. For all L&J SFI series field devices,the protocol can be set to a variety of different styles.Verify the programming of the SFI Transmitter toensure the comm. protocol is programmed asdesired.

Impact

Many gauges support multiple protocols, and validdata will not be received if WINGauge and the gaugeare configured for incompatible protocols. Thecorrect comm. protocol will normally be programmedby L&J prior to shipment of the system. It isimperative that the proper Comm. protocol beselected to match the field device protocol. If it is not,incorrect or no data at all will result for level andtemperature information. If the user cannot find theproper communication protocol in the provided list of

the gauging program, they should consult L&JTechnical support before attempting any systemconfiguration.

11 CorrectionFactor

Description

API volume correction factor (1.0 @ 60 DEG .F). Thisvalue is unitless and is a system calculated valuebased on the product temperature as well as the APItable chosen in the system configuration page. In themajority of cases, the system should be set to AUTO

for API table selection. This will allow the gaugingprogram to automatically select the proper API tablefor the given gravity and temperature.


Impact

Proper Correction factor calculations are imperativefor accurate Net Volume Calculations throughout thesystem. User should verify regularly that proper product temperature and gravity are available in thesystem for each tank to ensure accurate correctionfactors as well as Net Volume Calculations.

12 CPUPower

Description

MCG200SFI-only: This is the regulated power supplyvoltage being applied to the CPU board in the remotegauge. Nominally 5 volts DC, any significant changein this value may indicate a problem with the CPU's

power source or the on-board voltage regulator.


... ...

7/16/2019 3900 Manual




13 CPU Temp Description

MCG2000SFI-only: this value is the internal ambienttemperature of the gauge electronics package asmeasured from a thermal sensor mounted on theCPU board.


... ...

14 CriticalTime

Description

Given that a tank is in motion and that a flow rate hasbeen detected, Critical Time is defined as the timeremaining for the product level to reach the highalarm level (if the tank is filling) or the low alarm level(if the tank is emptying.) The software automaticallydetermines the correct level to use from the directionof flow.

The calculated value for Critical Time is based uponthe current flow rate, current gross volume, and theprogrammed alarm level (after conversion to thecorresponding volume.) During each update cycle,the difference between the current volume and theapplicable alarm volume is divided by the flow rate togive Critical Time. Critical Time is viewed on-screenas hours and minutes (hhh:mm). It appears as a datafield on Tank Detail page (see example below), theFastGauge display, and as a user-selectable columnoption in the Tank Groups display. It is also availableas a display field in the Dynamic Forms Generator.

In all cases, if a tank is not in motion (no levelchange) and/or the flow rate is zero, the symbol "N/A"(Not Available) will appear instead of a Critical Timevalue. The target values for Critical Time are specifiedhere, via the High High, Hi-Hi, Low and Low-Low level

alarm set points. In this example, the High Level set point (7.106meters) corresponds to 4000 barrels of product inthis particular tank. Likewise, the Low Level value of 3.549 meters indicates a volume of 2000 barrels of product. When the Critical Time displays as zero, oneof these levels has been reached. The Critical Timevalue shown in the preceding example is ten hours,zero minutes. This number was determined via thefollowing simple calculation: Gross Volume = 3000barrels Flow Rate = 100 barrels per hour High Alarm =7.106 meters or 4000 barrels. Critical Time = (4000 -3000) / 100, or 10 hours.


Impact

Allows user instant access to time remaining before

high or low alarm limits is exceeded, based upon thecurrent flow rate.

... ...

7/16/2019 3900 Manual




15 CurrentRate

Description

This is the rate (displayed in the rate units specifiedon the System Configuration page) at which productis flowing in or out of a tank. If the displayed number is positive, product is flowing into the tank. If thenumber is negative, product is leaving the tank. Thisnumber is not based upon actual flow measurements,but is derived from the change in product volumeover time.



Impact

An accurate current rate value is essential for thesystem to calculate an accurate critical time. Thisallows the user to see how long it will take to reach ahigh or low alarm point at the current Rate of flow.Level active/inactive and time active/inactiveparameters must be set correctly for the system todetect that a tank is active.

... ...

16 Dead Tank

Description

A Dead Tank is defined as one in which no levelchanges are expected. Furthermore, if a level changeis detected, it is to be considered a problem state.Thus, if a tank has the Dead Tank option enabled, analarm will be generated if any motion is detected onthe tank.

Code Function

ON Alarm on tank movement.


Usage

API is above target.

The Delta Volume is used in the Roof Correctioncalculation. An accurate delta volume value isessential when the system is taking into account theweight of a floating roof for Net Volume Calculations.

Usage

Open any of the listed pages in the Where Set columnfor this field and select the tank whose value is to bemodified. Either click directly upon the Delta Volumefield, or use the Tab key to navigate to the field. Typethe new Delta Volume value. The value is entered inthe system units chosen for Volume.

This value shold be set to zero if no roof connectionis used for Net Volume Calculations.

Impact

This setting affects volumetric calculations that occur within the specified Lower and Upper Critical Zonerange. This includes the Gross and Net Volumevalues, as well as the Available Product and AvailableStorage values. An accurate delta volume value isessential when the system is taking into account theweight of a floating roof for Net Volume calculations.

21 Enable 1

Enable 2

Description

These two settings determine how WINGaugeresponds to changes in the state of the discretedigital inputs. WINGauge supports two such inputs. If an Enable field is set to ON, then a positive-goingtransition in the corresponding input will trigger aDISCRETE ALARM, which will be logged into theAlarm Summary and Alarm History pages.For L&JTankway-based gauges, the input bit data isphysically returned as part of the Temperatureresponse. Consequently, if temperature scan is notenabled, monitoring of the discrete inputs will notoccur. See MCG2000 series manual for proper wiringand operation of discrete inputs.

Code Function

YES Discrete Alarms enabled.

NO Discrete Alarms disabled.

Usage

Open any of the listed pages in the Where Set columnfor this field and select the tank whose value(s) are tobe modified. Either click directly upon the desiredEnable field to toggle the option ON or OFF, or usethe Tab key to navigate to the field and tap theSpacebar.

25 GaugeAddress

Description

This field is where the numeric address of the remotegauge is entered into WINGauge. Each field deviceconnected to same part on the gauging system musthave it's own unique gauge address. This will allowthe gauging program to identify each tank and it'scorresponding level and temperature. Consult theusers manual of the level transmitter in use todetermine the proper procedure for setting gauge

address. Whenever possibble, it is advisable to setthe gauge address to match as close as possible tothe tank number. For example, Tank 1 set to address

1, Tank 2 to address 2, etc.

Usage

Open any of the listed pages in the Where Set columnfor this field and select the tank whose value is to bemodified. Either click directly upon the GaugeAddress field, or use the Tab key to navigate to thefield. Type the new Gauge Address value.The rangeof addresses that may be entered is protocol-specific.The address ranges for two of the most commonprotocols are shown in the following table:


Tankway 0 - 127

GPE 0 - 99

Attempting to enter an address that is out of therange of a particular protocol will result inunpredictable operation and communications failure.Negative address numbers are not allowed.

Impact If the entered Gauge Address does not correspond tothe address assigned to the remote gauge, nocommunication can or will take place. Even worse,the system may request data from the wrong tank!


26 GaugeHeight

Description

Gauge Height is defined as the distance from thebottom of the tank to top of the gauge fixtureattached to the top of the tank. This level value isentered when it is desired that the product level bedisplayed as an Outage level instead of an innagelevel. The system will subtract the level received fromthe remote level transmitter (Innage Level) from theentered gauge height. This level will be displayed asOutage level on the Tank Configuration page.

Usage

Open any of the listed pages in the Where Set columnfor this field and select the tank whose value is to bemodified. Either click directly upon the Gauge Heightfield, or use the Tab key to navigate to the field. Typethe new Gauge Height value. The value is entered inthe system units chosen for Level.

This value is always user-defined, and is required for proper operation with outage-based facilities.

This field is not normally visible on innage basedsystem.

Impact

This value is used for OUTAGE-based tank gaugingsystems (i.e., systems where the gauge returns levelreferenced from the top of the tank, instead of thebottom, and on innage-based equipment it must beset to zero or the volumetric calculations will notwork!

27 GrossVolume

Description

The Gross (uncorrected) Volume. The Gross Volumeis determined by indexing the current Product Levelinto the assigned Strapping Table for the tank. Nooffsets, scaling factors, or other corrections havebeen applied to the volume at this point.


Impact

Accurate product level measurement as well as a

properly entered strapping table are required for gross volume values to be calculated correctly.

28 Group

Code

Description

This is the alphanumeric code assigned to a group of related products. In other words, while each tank isgiven a product code which indicates the type of product stored in the tank, the group code refers toone or more tanks that contain products that are insome way similar. For example a product group of Crude Oil might have tanks containing different typesof Crude: Texas Sweet, Texas Sour, Low Sulfur, etc.

Usage The available Group Codes are defined externally tothe WINGauge in a separate data file. This file isnormally maintained by the system administrator.

Impact

Group Codes are used on the following displays andpages: Group Display, Group Summary, GroupSummary Graph and Inventory On-Hand.

They are also used on the printed Product Summaryand Inventory reports. To allow the gauging systemto accurately generate displays and reports for eachgroup of products, it is important that all productscodes related to a group code be assigned correctlyby the system administrator. Accurate inventoryreports are dependent on proper configuration of both product and group codes.

Input 1(discrete)

Input 2(discrete)

Description


Code Function



The MCG3900 supports discrete inputs as used onthe MCG2000 and MCG2000-SFI series of gauges, aswell as some older GPE products.

The appropriate Enable field must be set to YES onthe Tank Configuration page in order for the discreteinputs to be functional. If a Discrete Input is enabled,and it's state transitions from HIGH to LOW, aDiscrete Alarm will be logged to the Alarm Summaryand Alarm History pages, and an Emergency class alarm will be generated.


Usage

These are display-only fields and cannot be edited.User can wire in dry contact switches into thediscrete inputs on the MCG2000 series transmitter and the status of the switches will be transmittedback to the gauging computer. This will allowmonitoring of the switches through the tank gaugingsoftware. The status of the switches will only beshown as OPEN or CLOSE for the input status. Thesystem will generate a discrete input alarm when the

input changes from close to open.

Impact

Any type of dry contact switch can be wired into thediscrete inputs on a MCG2000 series leveltransmitter. When the switch opens on the discreteinput, the gauging system will display a Discreteinput alarm. It is important for all operators of thesystem to be made aware of exactly what isconnected to the discrete input so appropriate actioncan be taken in the event of a Discrete alarm.

35 LevelActive

Description

The Level Active field works in conjunction with the

Time Active field to determine whether a tank isACTIVE or INACTIVE. An active tank is one that is inmotion (i.e., experiencing a change in level.) Aninactive tank is one whose level is not changing.

In order for a tank to switch from the inactive state tothe active state, the level must change more than thespecified Level Active field within the specified TimeActive interval. For example: If the level active field isset to 5 and the time active field is set to 2, thesystem will consider the level active if the productlevel changes 5 or more sixteenths of an inch in 2minutes.

The tank will remain active as long as the levelcontinues to change at least 5 sixteenths every 2minutes. Level active parameters work the same

whether the tank level is going up or down.

Usage

Open any of the listed pages in the Where Set columnfor this field and select the tank whose value is to bemodified. Either click directly upon the Level Activefield, or use the Tab key to navigate to the field. Typethe new Level Active value. The value is entered in16ths of an inch.


Impact

The Level Active field affects all aspects of theprogram where tank activity is important. Thisincludes the Tank Movement field, the Active Tanksdisplay, the Dead Tank alarm, the Rate field, and theAutomatic Data Exporter.

37 LevelControl

Description

The Level Control field allows the user to toggle thefollowing real-time gauging parameters. There arefour small light bulbs in this field, each containing aletter code corresponding to the function the bulbcontrols, as follows:

Code Function

S

Scan

A Alarm Evaluation

M Manual Entry



Usage

Open any of the listed pages in the Where Set columnfor this field and select the tank whose value is to bemodified. Click on (S)can bulb to toggle Levelscanning on and off, click on the (A) bulb to turnAlarm Evaluation on or off, click on the (M) bulb toturn Manual Entry mode on or off, or click on the "C"bulb to turn Software Calibration on or off. When the

scan bulb is lit, the gauging program will send outrequests to the level transmitter requesting it to sendback level. The program will continuously sendrequests to the tank as long as the scan bulb is lit. If the scan bulb is not lit, the gauging program will notsend requests to the level transmitter.

When the Alarm Evaluation bulb is lit, the system willprocess any level, temperature, rate, etc. alarms thatoccur for the tank. This includes opening the alarmsummary window as well as sounding the audiblealarm for any new alarms encountered. If the alarmevaluation bulb is not lit, the system will not processany alarm conditions that occur for the tank. Thealarm condition will be ignored by the system and novisual or audible indicators for the alarm conditionwill occur. If the manual entry bulb is lit, thisindicates the displayed level was entered from the

keyboard manually and is not a level from a fieldtransmitter. The system will use this manuallyentered value for all calculations for the tank. If themanual entry bulb is not lit, this indicates that thesytem will try to interogate a field transmitter for levelprovided that the scan bulb is lit.

If the Software Calibration bulb is lit, this indicatedthat the displayed level has been offset by the user toread a level other than that received from the leveltransmitter.

If the transmitter is sending a level to the gaugingsystem of 12 feet 6 inches, but the user hasdetermined that the actual level in the tank is 12 feet 3inches, the Soft Cal. function can be used to makethe level read 12 feet 3 inches. This offset will be

used for the tank as long as the Soft Cal. button is lit.

Impact

If Level scanning is disabled, the system will notattempt to acquire updated Level values from theremote gauge, and the Product Level and variousproduct volume fields will reflect the last known gooddata. If level scan is disabled and the last known levelis not a good value, a manual entry should be usedfor product level. If level scan and manual entry areenabled at the same time, the manually entered levelwill be used by the system. The gauging system willstill scan the tank for product level but the returnedlevel will not be used until the manual entry isdisabled.

Usage

The Tank Control field allows the user to toggle thefollowing real-time gauging parameters. There aretwo small light bulbs in this field, each containing aletter code corresponding to the function the bulbcontrols, as follows:

Code Function

S Master Scan


This field works similarly to the other Control fields,however it does not control a specific data item:rather, it controls whether or not the other itemsperform their functions. For example, if the Master Scan bulb is dark (disabled) none of the other gaugepolling functions will work (level, temp, BS&W,

Density, etc.) This allows a gauge to be totallydeactivated with a single mouse click.

Impact

This setting will potentially stop all scanning of aselected tank for level, temp, etc. Even if level andtemp scan are enabled in their respective fields, thetank control field will still stop the system frompolling the remote transmitter. All alarm evaluationcan be disabled for a tank from the tank Control field.If this is selected, the system will ignore all alarmconditions that may occur and no visual or audiblewarnings will be present in the system.
