1 DESCRIPTION AND OPERATION

1.1 Application

The flowmeter is designed to measure the mass and volume flow, density, mass and volume of liquids and gases, and use the information obtained for technologi-cal purposes and accounting and settlement operations.

The flowmeter is used as a meter for gasoline, liquefied gas, kerosene, diesel fuel, oil, oil with water, fuel oil, other liquids and corrosive media under operating pres-sure and working temperature at chemical, petrochemical, oil, food, pharmaceuti-cal and other industries and public utilities.

Flowmeters are installed in automatic control, adjustment and operation systems and used at variable industries, stationary plants and ground-based mobile refuel-ing and transfer facilities, commercial accounting systems.

Flowmeters can be used for both safe and explosive environments. Ex-proof flowmeters EMIS-MASS 260-Ex are equipped with explosion-proof enclosure un-der GOST 30852.1, intrinsic safety of "ib" protection level under GOST 30852.10.

The mass meter EMIS-MASS 260 is an indicating device operating under exces-sive pressure, categories 1 and 2, in accordance with the requirements of TR TS 032/2013 “On safety of equipment operating under excessive pressure”.

Attention!

The flowmeter is not intended for operation at nuclear facilities.



1.2 Structure and Operation Principle

Flowmeter consists of the following assemblies (fig.1.1):

flow tube (sensor) (1);

transmitter (2).

Fig.1.1 - External view

Transmitter can be mounted integrally with sensor (integral version) and separate-ly from sensor (remote version).

The sensor is a measuring chamber with inlet and outlet pipes and flanges for pipeline connection. The magnetic coil and the magnet induce vibrations on the two U-shaped parallel flow tubes. The magnetic coil and the magnet induce vibra-tions on the two U-shaped parallel flow tubes. Electromagnetic coils with mag-nets, called detectors, are installed on the flow tubes.

When a measured medium moves through a measuring chamber, a physical phe-nomenon appears, known as the Coriolis effect (Figure 1.2). The progressive movement of the medium in the oscillating flow tube leads to the occurrence of Coriolis acceleration, which, in turn, leads to the appearance of Cor-iolis force. This force is directed against the motion of the tube imparted to it by the driver coil, i.e. when the tube moves up during the half of its own cycle, the Corio-lis force is directed downward for the fluid flowing inward. As the fluid passes through the bend of the tube, the direction of the force changes to the opposite Having been forced upward, the liquid flowing out of the sensor resists having its vertical motion decreased by pushing up on the tube. This action causes the tube to twist. When the tube is moving downward during the second half of its vibration cycle, it twists in the opposite direction.




Fig.1.2 - The forces affecting the tube during the vertical movement

Coriolis force and the amount of twist is directly proportional to the mass flow rate. The detectors measure the phase shift when the opposite sides of the flow tubes move, and as a result, out of phase signals are generated. Mass flow rate Q is proportional to time delay Δt .

Q = K * Δt / 3,6 , kg/h (1.0)

where K is a calibration coefficient g/s/µs Δt - time delay between the signals from the coils, µs

The density of the medium being measured is determined by measuring the pe-riod of oscillation of the flow tubes, which is proportional to the density of the medium. While calibrating the density measuring channel for two different fluids with known (measured with density meter) density (air and water) the period of oscillation of the flow tubes corresponding to this density shall be measured. Medium density and oscillation period shall be specified via the transmitter dis-play or digital interface. Due to the linear dependence based on the period of oscillation of the flow tubes we can calculate the density of the medium.

The integrated platinum sensor Pt100 measures the temperature. Measured tem-perature is used for automatic correction of the flow rate and density related to the temperature changes. Temperature correction coefficients for the flow rate and density are set as default at the plant and can be adjusted through the display menu.

The flow rate can be manually corrected depending on the pressure changes.

The sensor forms the primary signal containing the data on the time delay be-tween the sensors. The primary signal is transmitted to the transmitter mounted on the sensor or separately. The transmitter processes the primary signal, calculates mass and volume flow, temperature compensation, forms output signals and show these info on the display.

Transmitter can be mounted integrally with sensor (integral version) and separate-ly from sensor (remote version).



Measurement advantages:

direct measurement of mass flow rate in the pipeline without changes in parameters leading to further inaccuracy.

high precision and stability for a long time;

measurement of highly viscous fluids, non Newtonian fluids, fluids with solid and gas inclusions;

stable work despite vibration and twist in the pipeline, temperature and pressure changes;

no moving parts (small oscillation amplitude can be ignored) and wearing parts which extend the service life of the flowmeter;

no barrier for the flow path inside the tubes;

temperature and density measurement;

no straight pipes before/after the flowmeter or the flow straightener are re-quired.

Fluid specification is valid for water at 20ºС, pressure 0,1 to 0,2 MPa and 1000 kg/m3 density under normal conditions. For mediums with different density the limits of the measuring range for volume flow rate shall be calculated by dividing the above values of the mass flow range by density in g/cm3.

If measured flow is below the stated low flow cutoff value, the flowmeter will show zero flow and no total mass and volume will be counted. The low flow cutoff value is set to 1% of the maximum flow rate. If required, it can be decreased locally to avoid self running. The low flow cut off value can be changed through the menu or Mod-bus.

Flow density range from 600 to 3000 m3/h.

Maximum dynamic viscosity of the medium 1500 mPa * s.

Gas inclusions in fluid shall not exceed 1% of the volume for 0,1%, 0,15%, 0,25% and 3% for 0,5% accuracy flowmeters.

The maximum achievable flow rate shall be within the approved range.

The maximum achievable flow rate shall be within the approved range.

Gas flow range can be calculated as follows

QMG= QM * ρg / kГ (1.1)

Qmg – actual flow, kg/h; Qm – actual flow, kg/h; Ρg – gas density, kg/cbm Kg = 70 kg/cbm – empirical coefficient.

When using the mass flowmeter EMIS-MASS 260 for gas medium the display, fre-quency and digital output signals show only mass and mass flow values .

1.3.6 Output signals Flowmeters have the following output signals:

pulse signal;

analog current signal

RS-485 digital signal

HART digital signal Integrated indicator is used to display mass flow, volume flow and other measured parameters.

1.3.6.1 Pulse output signal

Pulse signal is a periodic square wave signal whose frequency varies linearly with mass flow rate including the user-adjustable damping time, see menu line 49.

The pulse output can be adjusted to read mass, volume flow rate or density. Pulse output can be active or passive depending on the flowmeter version.

The number of pulses correlates with the mass or volume of the medium passed through the flowmeter during the measured time.

Maximum frequency (fmax) of the output signal is as follows:

fmax = Qmax / (3,6*m), Hz

QМmax – upper limit of the full range, kg/h.

m- pulse value, g/pulse.

Output frequency range varies from 0 to 10000 Hz. It can be extend up to 12000 Hz

Output signal amplitude is 24V (for the flowmeters produced before 01/06/2018 the amplitude is 13V). Schematic diagram of the pulse output signal is presented in Fig-ure 1.3.

Default pulse value is shown in Table 1.5.

Recommendations

1 While measuring liquids it is recommended to install flowmeter so that measuring chamber is downward to provide better flooding and so gases cannot get trapped inside the tubes.

2 While measuring gases it is recommended to install flowmeter so that measuring chamber is upward to avoid the condensation accumulated in the tubes.

3 If the pipeline is vertical or inclined, the most desired installation is on the section with upward flow direction to provide better flooding. Vertical in-stallation is also recommended if the medium has gaseous impurities.

RECOMMENDATON If the flowmeter is installed so that the measuring chamber is upward, it it rec-ommended to chosoe remote type flowmeter to provide convenient reading of values from the indicator. The flowmeters with electronic unit of “U” type have function to turn display by 180 degrees.

If the pipeline is bent, it is recommended to install the flowmeter in the lower section of the pipeline. It is prohibited to install the flowmeter in the horizontal pipe prior to freely falling of the stream, otherwise the measuring pipe will not be filled enough.

Attention!

When choosing and designing the place of flowmeter installation it is IMPORTANT to comply with requirement to full fill the flowmeter cavity with medium. Otherwise, working ability of flowmeter is not guaranteed.




2.3.3 Preparation of pipeline

To prepare for installation please follow the steps below:

check for flanges, fasteners, clamps, couplings and its parameters (see Appendix A);

cut the pipeline of L length Linst = Lflm + 2*Lgas + 2*Lcfl, (2.1)

where Linst - installation length of flowmeter (see protection Appendix A); Lgas - gasket width; Lfl- counter flange width after deduction of installation length;

mount counter flanges in the pipeline;

use mounting coupling to align flanges, them weld them to the pipeline.

Attention!

It is allowed to use flowmeter as coupling in cases listed below: - gas welding is used for mounting; - for arc-welding power source is connected so that current does not flow throught the flowmeter - see fig.2.3.

Right Wrong

Fig.2.3 - Power supply connection for arc-welding

Installation place shall look as it shown on fig.2.4, where L is sum of flowmeter length and gaskets width.

2.5.3.2 U version dis-play

While equipment is in operation the information about measuring values is display-ing on the screen. To simplify control of measured values, values are divided for 2 groups:

1) User values (see Table 15).

2) System values (see Table 16).

User values are displayed on 2 user screens, access to user screens is unlimited. The screens are setting line by line - every line is set with user value. There are four lines on the screen. Please, note that totalizers fill in 2 lines.

System values are displayed on 2 screens as user`s. But appropriate access level is required to display system screens. The screens are setting line by line, it means that every of four lines can be set with any system value.

To switch over between screens use buttons “left”, “right”,”up”, “down” (see Table 2.9).

To enter menu of the equipment use buttons “chose/enter” and “cancel” (see Table 2.9).

Menu navigation and changing of parameters values is implemented via buttons from the Table 2.9.

2.5.4 Zero point adjust-ment

Zero point settings shall be made after mounting and electrical connection. Refer-ence point corresponding to zero flow is entered by adjusting zero point. To make the settings do as follows:

apply the power to the flowmeter and let it warm up for 30 minutes;

let the flow through the flowmeter until thermal balance is reached;

close the stop valve located downstream from the flowmeter;

make sure that the flow tubes are filled with the medium;

close the stop valve located upstream from the flowmeter; make sure that there is no flow inside;

For electronic unit of standard version:

in the root menu (see fig.2.14) of the display press ↓ button until Settings is displayed. Press E and enter the password (default password is 000000). To enter the password press ↓ to increment the currently selected digit. To move to the next digit press → button. After successful password entry a message “Zero calibration” will appear. If after password entry it is switched to another menu, press ↓, and the Flow config will appear. Then press E to go to “Zero calibration” will appear. To start zero calibration press E. A message “Start?” will appear. Press E to confirm. Zero calibration takes 30 seconds, the remaining time will be displayed.

In the root menu (see fig.2.14) on the display press button □ or ○ to

call service menu, choose “Zero correction” and press ○. Enter the password (ini-

tial password is 000001). To enter the password press ↓ to increment the currently selected digit. To move to the next digit press → button. After enter correct pass-

word to start zero calibration press ○. A message “Start?” will appear. Press ○ to

confirm. Zero calibration takes 30 seconds, the remaining time will be displayed. You should proceed zero calibration if: - the flowmeter indicates the flow when there is no actual flow at the moment; - physical properties of the medium have changed.

Attention!

Zero correction shall be implemented if it is guaranteed that there are no flow or medium moving inside the flowmeter. To be sure zero correction procedure is correct, it is recommended to repeat it 3-5 times and control zero point sta-bility.

It is recommended to switch off the flowmeter if no flow is expected for the long time (flow tubes are empty).

2.5.5 Oil components analyzer

This function lets to calculate pure oil and water content in emulsion flow by com-paring measured density of emulsion with standard density of pure oil and water.

For electronic unit of standard version:

When switching on the function “Oil content” it is required to enter density value of pure oil (menu 53 of flowmeter) in menu 52 of flowmeter (Table 2.8) and density value of water (menu 54 of flowmeter). There will be displayed water content,% in measured medium and oil mass value on the display (menu 2a).

Reading mass value, mass flow of pure oil, density of measured medium, entering density values of pure oil and water is available via digital output (register address-es are in Appendix D “EMIS register map”). For electronic unit of “U” version: When switching on the function “ Oil calculator” in menu ( Fig. 2.15) it is required to enter density value of pure oil and water while 20 C (Table 12. There will be dis-played water content,% in measured medium and oil mass value on the display.

Reading mass value, mass flow of pure oil, density of measured medium, entering density values of pure oil and water is available via digital output (register address-es are in Appendix F “Register map of electronic unit U1-U3 “EMIS”).

REGISTER MAP OF ELECTRONIC TRANSMITTER U1… U3 (EMIS)

Protocol interface have almost the same functions as Modbus RTU (Rev.G). The following functions are sup-ported:

Command (function) Function code (HEX) Sub-Function code (HEX)

Common commands: Read Input Registers 04 Read Holding registers 03 Report slave ID 11 Write Multiple Coilz 10 Activate relay 05 Change access level (remote input of a password) 43

See description of special functions for detailed information.

Function 04h (read input registers)

This function can be used to read input registers. Further the following codes will be used for register format description:

Float- 32-bit binary IEEE floating point number

Unit 32 32-bit binary without point

Registers of more than 32-bits are saved in two sequentially located logic addresses in low word-high word order. Standard request-response format. Both permissible data type take two registers, that is why requested data address and register quantity in all commands shall always have even value.

Float integers consist of 4 bytes, for example, in IEEE754 0,01 is represented as 3С23D70A. In this version of protocol for this number the bytes are transferred in the sequence of d7, 0a, 3c, 23 for Holding registers and in the sequence of 0a, d7, 23, 3c for Input Registers. Byte transfer sequence for Input Registers is pro-grammed.

Numbers in format Uint32 and Int32 consist of four bytes. In this version of protocol for number 12d756a0h the bytes are transferred in the sequence of 56, a0, 12, d7 for Holding registers and in the sequence of a0, 6a, d7, 12 for Input Registers. Byte transfer sequence for Input Registers is programmed.

Numbers in format Double consist of 8 bytes. For example, the number 0,23 in format IEEE754 in hexadeci-mal form looks like 0x3fcd70a3d70a3d71. In this version of protocol for this number the bytes are transferred in the sequence of : 3D, 71, D7, 0A (lower nibble) 70, A3, 3F, CD (higher nibble). To read and record data of this format by one command. The numbers in format Double are stored in module of four placed in a succes-sive order registers. After data recording in Double format, please read to check.

The limit for data block request corresponds to common Modbus RTU.

Function 03h (read holding registers)

Comments to the tables.

Variables in floating point format (float) and 32-bit integer number without a sign (int32) take two successive registers. In this case register with smaller number is mentioned as address.

Holding registers are read by function 03, modified by 16 (10 Hex).

Input registers are read by function 04.

Access levels are coded in the following way: No. 0 - can be modified by the user, levels 1 and 2 - modifica-tion is possible after input the password of corresponding or higher access level only, level 3 - registers can be modified when switcher is on SW1:1 on the mother board only, level 4 - read only, modification is impossible.

For tables with parameters in floating point format the address of first element of the table is mentioned, every next element is increased for 2. The reason - every number with floating point is placed in two 16-bit Modbus registers.

7.5.1.1 The flowmeter is subject to verification in the manner prescribed by PR 50.2.006-94 in accordance with the calibration procedure EM-260.000.000.000.01 MP.

7.5.2.2 The procedure for controlling the accuracy of measurement results is set out in the operating instructions for the measurement unit.

7.5.2.3 The following indicators and parameters are monitored:

- the absence of malfunctions of the flowmeter readings by periodically comparing them with the readings of similar SI installed on other IT, or comparing the read-ings with the backup system (if any) of the flow rate measurements;

- MX flowmeter;

- medium flow rate through IT, operating pressure and temperature, which should be within the established ranges;

- compliance with the requirements of the measurement conditions;

- zero offset of the flowmeter.

7.5.2.4 The intervals for conducting the next MX inspection are set taking into account the op-erating conditions of the flowmeter and the requirements for the accuracy of measurements as agreed by the parties concerned. Extraordinary control is carried out at the request of one of the parties.

7.5.2.5 Control of the flowmeter MX should not impede the measurement of flow in the pre-scribed manner.

7.5.3 Monitoring the accuracy of flowmeter measurements

7.5.3.1 Checking zero offset

7.5.3.1.1 Checking zero offset

- during the first month after installing the flowmeter;

- every season during the first year of operation of the flowmeter (the frequency of subse-quent periodic zero checks is determined by the operating conditions of the flowmeter, the requirements for accuracy of measurements, the results of previous checks);

- when the values of temperature and pressure of the measured medium or ambient tem-perature go beyond the limits at which the bias exceeds zero stability;

- periodically, with a frequency determined on the basis of the results of previous inspec-tions, taking into account the operating conditions of the flowmeter.

7.5.3.2 Monitoring the metrological characteristics of the flowmeter

7.5.3.2.1MX flowmeter control is carried out at the request of the user's regulatory docu-ments.

The following installation options for the control measuring instrument are used:

a) on working IT before or after the working flowmeter for the period of control of the MX working flowmeter. After control, instead of the control SI, a mounting insert is installed;

b) on control IT, the serial connection of which with IT workers is ensured by means of an additional piping.

The control SI can be installed both permanently and temporarily, for the period of control of the MX working flowmeter. In the case of temporary installation, after monitoring the MX flowmeter, a mounting insert is installed instead of the control SI.

7.5.3.2.2 During the control, at least three measurements of the controlled process pa-rameter (mass, volume, density or temperature) are carried out at a stable flow rate. The accumu-lation time for each measurement should be at least 30 s.

7.5.3.2.3 The control result is considered positive if for each meet the condition

where mk and msk - the value of the process parameter according to readings of \ con-trolled flowmeter and control SI;

U’msk - the limit of the relative expanded uncertainty of the flowmeter control means (in-cluding the error of the secondary equipment);

U’mк - the limit of the relative expanded uncertainty of the controlled flowmeter (including the error of the secondary equipment);

if the condition is not satisfied for one of the measurements, its result is excluded and one additional measurement is carried out.

7.5.3.2.4 In case of non-compliance with the conditions for two or more measurements and in case of repeated non-fulfillment of the additional measurement, find out the reason that caused the non-fulfillment of the condition, take measures to eliminate it and carry out a repeated control.

7.5.3.2.5 In case of a negative result of the inspection, the flowmeter shall be repaired and inspected or calibrated extraordinary.

8. Requirements to the personnel

8.1 At least 18 years of old staff who has qualification, have been instructed at the workplace, in-structed abot labor protection, safety, fire safety, knowledge testing and a medical examination is allowed to prepare and take measurements, process results.

8.2 The operating personnel must be familiar with the contents of present Operational manual.
