2.1 First InspectionThe flowmeter has already been tested thoroughly at the factory. At delivery, proceed to a visual control to make sure that no damage has occurred during transportation.

Check that the specifications of the flowmeter delivered correspond to the specifications given on the purchase order.

Type and serial number of the flowmeter are given on the data plate. The transducer type is printed on the transducers.

2.2 General Precautions

FLUXUS is a precision measuring instrument and must be handled with care. To obtain good measurement results and not to damage the instrument, it is important that great attention is paid to the instructions given in this user manual, and particularly to the fol-lowing points:

• Protect the flowmeter from excessive shock.

• Do not open the housing without authorization. The degree of protection of the flowme-ter is only guaranteed if the cables fit firmly and tightly in the cable glands, the cable glands are firmly tightened and the housings have been tightly screwed.

• Keep the transducers clean. Manipulate the transducer cables cautiously. Avoid ex-cessive cable bend.

• Make sure to work under ambient and operating temperatures. The ambient tempera-ture must be within the operating temperature range of the flowmeter and of the trans-ducers (see annex A, section Technical Data).

• Take the degree of protection into account (see annex A, section Technical Data).

2.3 Cleaning• Clean the flowmeter with a soft cloth. Do not use detergents.

• Remove traces of acoustic coupling compound from the transducers with a soft paper tissue.

3 Flowmeter

3.1 Measuring PrincipleThe flow of the medium is measured by ultrasonic signals using the transit time differ-ence method.

Ultrasonic signals are emitted by a transducer installed on one side of a pipe, reflected on the opposite side and received by a second transducer. The signals are emitted alter-natively in and against the flow direction.

As the medium in which the signals propagate is flowing, their transit time in flow direc-tion is shorter than against the flow direction.

The transit time difference t is measured allowing to determine the average flow velocity on the propagation path of the ultrasonic signals. A flow profile correction is then per-formed to obtain the area average of the flow velocity, which is proportional to the volume flow.

The received ultrasonic signals will be tested for usefulness for the measurement and the plausibility of the measured values will be evaluated. The complete measuring procedure will be controlled by the integrated microprocessors.Disturbance signals will be eliminat-ed by statistical signal processing.

4 Selection of the Measuring Point


The correct selection of the measuring point is crucial for achieving reliable measure-ment results and a high measuring accuracy. A measurement must take place on a pipe in which

• the ultrasound propagates with sufficiently high amplitude (see section 4.1)

• the flow profile is fully developed (see section 4.2)

• the influence of noise is sufficiently low (see section 4.3)

The correct selection of the measuring point and thus, the correct transducer positioning guarantees that the sound signal will be received under optimum conditions and evaluat-ed correctly.

Because of the variety of applications and the different factors influencing the measure-ment, there can be no standard solution for the transducer positioning. The correct posi-tion of the transducers will be influenced by the following factors:

• diameter, material, lining, wall thickness and form of the pipe

• medium.

Avoid locations where deposits are building in the pipe. The ambient temperature at the measuring point must be within the operating temperature range of the transducers.

Select afterward the location of the instrument within cable reach of the measuring point. Make sure that the ambient temperature at the location is within the operating tempera-ture range of the flowmeter (see annex A, section Technical Data).

If the measuring point is within an explosive atmosphere, the danger zone and gases which may be present have to be determined. The transducers and the flowmeter have to be appropriate for these conditions.

4.1 Acoustic PenetrationIt must be possible to penetrate the pipe with acoustic signals at the measuring point. The acoustic penetration is reached when pipe and medium do not attenuate the sound signal so strongly that it is completely absorbed before reaching the second transducer.

The attenuation of pipe and medium depends on:• kinematic viscosity of the medium• proportion of liquid and solids in the medium• deposits on the inner pipe wall• pipe material


Note! Avoid measuring points in the vicinity of deformations and defects of the pipe and in the vicinity of welds.

16 UMADM8X27V1-7EN 31.7.2009


The following conditions have to be observed at the measuring point:

• no material deposits in the pipe

• no accumulation of liquid (condensate), e.g. before orifice plates or at pipe sections lo-cated lower

4.2 Undisturbed ProfileMany flow elements (elbows, slide valves, valves, control valves, pumps, reducers, dif-fusers, etc.) distort the flow profile in their vicinity. The axisymmetrical flow profile needed for correct measurement is no longer given. A careful selection of the measuring point helps to reduce the impact of disturbance sources.

It is most important that the measuring point is chosen at a sufficient distance from any disturbance sources. Only then it can be assumed that the flow profile in the pipe is fully developed. However, measuring results can be obtained even if the recommended dis-tance to disturbance sources can not be observed for practical reasons.

Recommended straight inlet and outlet pipe lengths are given for different types of flow disturbance sources in the examples in Table 4.2.

Table 4.1: Recommended mounting position

Horizontal pipe

Select a measuring point where the transducers can be mounted on the side of the pipe, so that the sound waves propagate horizontally in the pipe. Thus, solids deposited on the bottom of the pipe and the gas pockets developing at the top will not influence the propagation of the signal.

4.3 Influence of NoiseThe ultrasonic waves do not propagate only in the medium but also in the pipe wall (see Fig. 4.1). They will be reflected at flanges.

Fig. 4.1: Propagation of ultrasonic waves

The reflected pipe wall signals can disturb the measurement, especially if:

• the measuring point is close to the reflection point

• the pipe wall and measuring signals are received by the transducer at the same time

4.4 Selection of the Measuring Point Taking into Account Flow Profile and Influence of Noise

• Select a measuring point area where the flow profile is fully developed (see section 4.2).

• Select the measuring point within this area so that the influence of noise can be ne-glected (see 4.3).

Considering flow profile and influence of noise, the measuring point can be selected in the area 3...(7.5 - 2) D on the right side of pipe segment 2 (with max. distance from the el-bow). In the example, a distance of 36 D from the elbow was selected.

example: medium: natural gaspipe material: stainless steellength of pipe segment 1: 20 Dlength of pipe segment 2: 20 Dnumber of sound paths: 2

• measuring point area with developed flow profile:

disturbance source: 90° elbowrecommended measuring point area: l 20 D (complete pipe segment 2) (see Table 4.1)

• measuring point area with low influence of noise:

reflection point: flangerecommended measuring point area: l 3 D and outside of l = (7.5 ± 2) D on pipe segment 2 (see Table 4.1)

22 UMADM8X27V1-7EN 31.7.2009


Both demands can not be observed always at the same time. In these cases, the mea-suring point has to be selected so that the influence of noise is min. and the measuring point is as far as possible from disturbance sources of the flow profile.

In the example, there is no measuring point area where both demands are met at the same time. The measuring point has to be selected as far as possible from the elbow, at a point where the influence of noise can be neglected: 3...(7.5 - 2) D on the right side of pipe segment 1. In the example, a distance of 16 D from the elbow was selected.

8.2 Input of the Medium Parameters

The media to be displayed in the scroll list can be selected (see chapter 12.5).

For the programmed parameters of common media see annex C, Table C.3.

If a medium is selected from the scroll list, the menu item for the input of the medium temperature is displayed directly (see section 8.2.5).

If OTHER MEDIUM is selected or no data set for the selected medium is stored in the flow-meter (e.g. natural gas, as the parameters depend on the composition of the natural gas), the medium parameters have to be entered first:

• min. and max. sound velocity

• kinematic viscosity

• density

• gas compressibility factor

8.2.1 Sound Velocity

The sound velocity of the medium is used for the calculation of the transducer distance at the beginning of the measurement. However, the sound velocity does not influence the measuring result directly. Often, the exact value of the sound velocity for a medium is un-known. A range of possible values for the sound velocity must therefore be entered. These displays are indicated only if OTHER MEDIUM has been selected.

8.2.2 Kinematic Viscosity

The kinematic viscosity influences the flow profile of the medium. The entered value and other parameters will be used for the profile correction. This display is indicated only if OTHER MEDIUM has been selected. or no data set for the selected medium is stored in the flowmeter (e.g. natural gas)

Select the medium from the scroll list.

8.2.3 Density

The mass flow will be calculated on the base of the density (product of volume flow and density). This display is indicated only if OTHER MEDIUM has been selectedor no data set for the selected medium is stored in the flowmeter (e.g. natural gas).

8.2.4 Gas Compressibility Factor

The gas compressibility factor is needed for the calculation of the standard volume flow (see section 9.1.1). Take care that the value is selected corresponding to the operating pressure, the operating temperature and the composition of the gas. This display is indi-cated only if OTHER MEDIUM has been selected or no data set for the selected medium is stored in the flowmeter (e.g. natural gas).

8.2.5 Medium Temperature

The medium temperature is used for the interpolation of the sound velocity and for the calculation of the recommended transducer distance and for the calculation of the gas compressibility factor at the beginning of the measurement.

During measurement, the medium temperature is used for the interpolation of density and viscosity of the medium.

8.2.6 Medium Pressure

The medium pressure will be used for the interpolation of the sound velocity and of the gas compressibility factor . This display is indicated only if in SPECIAL FUNC-TION\SYSTEM SETTINGS\DIALOGS/MENUS\GAS MEASURING is activated or if GAS MEASURING is deactivated andSPECIAL FUNCTION\SYSTEM SETTINGS\DIALOGS/MENUS\FLUID PRESSURE has been activated.

8.5 Define Number of Sound PathsThe number of transits of the ultrasonic waves through the medium depends on the placement of the transducers on the pipe.

If the number of transits is odd (diagonal mode), the transducers will be mounted on op-posite sides of the pipe.

If the number of transits is even (reflection mode), the transducers will be mounted on the same side of the pipe.

An increased number of transits means increased accuracy of the measurement. Howev-er, the increased transit distance results in a higher attenuation of the signal.

The reflections on the opposite pipe wall and deposits on the inner pipe wall cause addi-tional amplitude losses of the sound signal.

Note! A channel can not be activated if the parameters are not valid, e.g. if the parameters in the program branch PARAMETER of the channel are not complete.

8.7.4 Consistency Check

If a wide range for the sound speed has been entered in the program branch PARAMETERor the exact parameters of the medium are not known, a consistency check is recom-mended.

The transducer distance can be displayed during measurement by scrolling with key .

The optimum transducer distance is calculated on the basis of the measured sound speed. It is therefore a better approximation than the first value which had been calculat-ed on the basis of the approximate sound speed range entered in the program branch PARAMETER.

If the difference of optimum and entered transducer distance is less than specified in Ta-ble 8.1, the measurement is consistent and the measured values are valid. The measure-ment can be continued.

If the difference is greater, adjust the transducer distance to the displayed optimum val-ue. Afterwards, check the signal quality and the signal amplitude bar graph (see section 8.7.3). Press ENTER.

The optimum transducer distance (here: 50.0 mm) will be displayed in parentheses in the upper line, followed by the entered transducer distance (here: 54.0 mm). The latter value must correspond to the actually adjusted transducer distance. Press ENTER to optimize the transducer dis-tance.

8.7.5 Value of the Sound Speed

The sound velocity of the medium can be displayed during measurement by pressing key .

If an approximate range for the sound speed has been entered in the program branch PARAMETER and the transducer distance has been optimized afterwards as described in section 8.7.4, it is recommended to note the sound velocity for the next measurement. The optimization procedure does not need to be repeated then.

Also note the medium temperature as the sound speed depends on the temperature. The value can be entered in the program branch PARAMETER or a user defined medium can be defined for this sound velocity (see section 12.2 and 12.3).

8.8 Start of Measurement

If the standard volume flow is selected as physical quantity during the gas measurement, the operating volume flow can be displayed, too.

If more than one measuring channel is available/activated, the flowmeter works with an integrated measuring point multiplexer providing quasi simultaneous measurement on the different measuring channels. The flow is measured on one channel for approx. 1 s, then the multiplexer switches to the next activated channel.

The measuring time depends on the measuring conditions. If, e.g. the measuring signal can not be detected immediately, the measurement might take longer than 1 s.

Enter the new adjusted transducer distance. Press EN-TER.

Scroll with key again until the transducer distance is displayed and check the difference between optimum and entered transducer distance. Repeat the steps if neces-sary.

Note! Never change the transducer distance during measurement without having restarted the consistency check.

The measured values will be displayed in the lower line. Press ENTER to return to the fine adjustment of the trans-ducer distance (see section 8.7.3).

Press key to display the standard volume flow.

9.1.1 Measurement of the Standard Volume Flow

If the medium is a gas, the standard volume flow can be selected as physical quantity ad-ditionally to the operating volume flow. The standard volume flow will be calculated as follows:

VN = V * p/pN * TN/T * 1/K

VN - standard volume flowV - operating volume flowpN - standard pressure (absolute value)p - operating pressure (absolute value)TN - standard temperature in KT - operating temperature in KK - gas compressibility factor

Standard pressure pN and standard temperature TN will be entered in SPECIAL FUNC-TION\SYSTEM SETTINGS\GAS-MEASURING\NORMAL PRESSURE and NORMAL TEM-PER.

Operating pressure p and operating temperature T will be entered in PARAMETER\FLUID PRESSURE and MEDIUM TEMPERAT.

The gas compressibility factor K is stored in the medium data set. If OTHER MEDIUM is selected or a data set for the selected medium does not exists, the gas compressibility factor will be entered in PARAMETER\GAS COMPR.FACTOR. Take care that the value is selected corresponding to the operating pressure, the operating temperature and the composition of the gas.

10.4 Upper Limit of the Flow VelocitySingle outliers caused by heavily disturbed surroundings can appear in the measured values of the flow velocity. If outliers are not ignored, they will affect all derived physical quantities, which will then be unsuitable for integration (e.g. pulse outputs).

It is possible to ignore all measured flow velocities higher than a preset upper limit. These measured values will be marked as outliers.

The upper limit of the flow velocity will be set in SPECIAL FUNCTION\SYSTEM SET-TINGS\MEASURING\VELOCITY LIMIT. The setting is cold start resistant.

If the flow velocity is higher than the upper limit,

• the flow velocity will be marked as invalid. The physical quantity can not be deter-mined.

• the LED of the measuring channel will light red

• "!" will be displayed after the unit of measurement (in case of a normal error, "?" is dis-played

Note! The overflow of a totalizer influences all output channels, e.g. data memory, online output.

The output of the sum of both totalizers (the throughput Q) via an output will not be valid after the first overflow (wrapping) of one of the corresponding totalizers.

To signalize the overflow of a totalizer, an alarm output with switching condition QUANTITY and type HOLD has to be activated.

Enter 0 (zero) to switch off the detection for outliers.

Enter a limit > 0 to switch on the detection for outliers. The measured flow velocity will be compared then to the entered upper limit.

Values between 0.1 m/s and 25.5 m/s will be accepted.

Press ENTER.

Note! If the upper limit is too low, a measurement might be impossible, as most of the measured values will be marked "invalid".

10.5 Cut-off FlowThe cut-off flow function automatically sets all measured flow velocities to zero that are below a preset value. All values derived from this measured value will also be set to zero.

The cut-off flow can depend on the flow direction or not. Default is 2.5 cm/s (0.025 m/s). The max. value is 12.7 cm/s (0.127 m/s). The cut-off value will be set in SPECIAL FUNCTION\SYSTEM SETTINGS\MEASURING\CUT-OFF FLOW. The setting is cold start resistant.

If CUT-OFF FLOW\SIGN and USER are selected, two values have to be entered:

If CUT-OFF FLOW\ABSOLUT and USER is selected, only one value has to be entered:

Select SIGN to define a cut-off flow dependent on the flow direction. There are two independent limits to be set for the positive and negative flow directions.

Select ABSOLUTE to define a cut-off flow independent of the flow direction. There is only one limit to be set. The absolute value of the measured value will be compared to the cut-off flow.

Select FACTORY to use the default value of 2.5 cm/s (0.025 m/s) for the cut-off flow.

Select USER to enter the cut-off flow.

Press ENTER.

Enter the cut-off flow for positive measured values. All positive values of the flow velocity less than this limit, will be set to zero.

10.6 Uncorrected Flow VelocityFor special applications, the uncorrected flow velocity might be of interest.

The profile correction of the flow velocity will be activated in SPECIAL FUNCTION\SYS-TEM SETTINGS\MEASURING\FLOW VELOCITY. The setting is cold start resistant.

Uncorrected flow velocities transmitted to a PC will be marked by UNCORR.

Select NORMAL to display and output the flow velocity with profile correction.

Select UNCORR. to display the flow velocity without profile correction. Press ENTER.

If UNCORR. is selected, it has to be confirmed each time the program branch MEASURING is selected whether to use the profile correction.

10.7 Measurement of Transient Processes (FastFood mode) The FastFood mode allows to measure flows with high dynamics. The continuous adap-tation to changing measuring conditions which takes place in the normal measuring mode is only partially realized in FastFood mode.

The sound velocity of the medium is not measured. The flow velocity stored in the inter-nal database will be used instead, taking into account the medium temperature entered in the program branch PARAMETER.

A change of measuring channel is not possible. The outputs can still be used. The mea-sured values are stored as usual. The FastFood mode has to be enabled and activated.

10.7.1 Enabling/Disabling the FastFood Mode

10.7.2 Storage Rate of the FastFood Mode

10.7.3 Activating/Deactivating the FastFood Mode

If the FastFood mode is enabled and a measurement started, the normal measuring mode is still running (i.e. multi-channel measurement with permanent adaptation to the measuring conditions). If the data memory is activated, the measured values will not be stored.

If the data memory is activated, a new data set will be defined and storing of measured values will be started. If the FastFood mode is deactivated or if the measurement is inter-rupted, storing will be stopped.

Enter HotCode 007022 (see section 7.3). The menu item ENABLE FASTFOOD will be displayed.

Select YES to enable the FastFood Mode, NO to disable it.

When the FastFood mode is enabled, a STORAGE RATE in ms has to be entered in the program branch OUTPUT OP-TIONS.

10.8 Calculation Channels

Additionally to the ultrasonic measuring channels, the flowmeter has two virtual calcula-tion channels Y and Z. The measured values of the measuring channels A and B will be summed up by the calculation channels.

The result of the calculation is the measured value of the selected calculation channel. This measured value is equivalent to the measured values of a measuring channel. All operations with the measured values of a measuring channel (totalizing, online output, storing, outputs, etc.) can be done with the values of a calculation channel, too.

10.8.1 Characteristics of the Calculation Channels

In the program branch PARAMETER, the measuring channels to be used for the calcula-tion and the calculation function have to be entered.

A calculation channel can not be attenuated. The damping factor has to be set separately for each of the two measuring channels.

Two cut-off flows for each calculation channel can be defined. The cut-off flow is not based on the flow velocity as for measuring channels. Instead it will be defined in the unit of measurement of the physical quantity selected for the calculation channel. During measurement, the calculated values are compared to the cut-off flow values and set to zero if necessary.

A calculation channel provides valid measured values if at least one measuring channel provides valid measured values.

10.8.2 Parameterization of a Calculation Channel

Note! The values of the current measuring data set will be deleted when the FastFood mode is deactivated and activated again without inter-rupting the measurement.

Note! The values of the current measuring data set are kept if the measure-ment has been interrupted before the FastFood mode is activated again. A new measuring data set will be created when the next mea-surement is started.

Note! Calculation channels are only available if the flowmeter has more than one measuring channel.

Select a calculation channel (Y or Z) in the program branch PARAMETER. Press ENTER.

The current calculation function will be displayed. Press ENTER to edit the function.

12 LibrariesThe internal material database of the flowmeter contains parameters for pipe and lining materials as well as for media. It can be extended cold start resistant by user defined ma-terials or media. User defined materials and media will always be displayed in the scroll lists of the program branch PARAMETER.

User defined materials and media can be stored in an integrated coefficient memory (us-er area). The coefficient memory has to be partitioned first (see section 12.1).

The properties of user defined materials or media can be entered as follows:

• as constants without the extended library (see section 12.2)

• as constants or temperature and pressure dependent functions by means of the ex-tended library (see section 12.3)

The material and media scroll lists displayed in the program branch PARAMETER can be arranged here (see section 12.5). The shorter scroll lists make the work more efficient.

12.1 Partitioning of the Coefficient MemoryThe coefficient memory can be arbitrarily parted among the following material data:

• material properties:- transversal and longitudinal sound velocity- typical roughness

• medium properties:- min. and max. sound velocity- kinematic viscosity- density- gas compressibility factor

The max. number of data sets for each category of these material data is indicated in Ta-ble 12.1.

12.3 Extended Library

12.3.1 Introduction

If the extended library is activated, material and medium properties as function of the temperature or of the pressure can be entered to the flowmeter directly or by means of the program FluxKoef.

For an overview of the material properties to be entered and of the measuring processes they are needed for see Table 12.2.

Enter only the properties needed for the measuring task.

The dependency of certain material properties from the temperature and pressure can be described

• as constants

• as linear function

• with polynomials of grade 1 to 4

• with customized interpolation functions

Constants or a linear function are sufficient in most cases.

If e.g. the temperature fluctuations at the measuring point are low compared to the tem-perature dependency of the material properties, the linearization or the complete neglect of the temperature dependency will not result in a considerable additional measuring er-ror.

If, however, the process conditions fluctuate strongly and the medium properties depend strongly on the temperature (e.g. viscosity of hydraulic oil), polynomials or customized in-terpolation functions should be used. In case of doubt, contact FLEXIM to find the best solution for the measuring task.

Enter the density of the medium. Press ENTER.

15.3 Activation of an Analog Output

15.3.1 Measuring Range of the Analog Outputs

After an analog output has been activated in the program branch OUTPUT OPTIONS, the measuring range of the source item has to be entered.

From now on, the error value delay can be entered in the program branch OUTPUT OPTIONS. The setting is cold start resistant.

Note! An output can only be activated in the program branch OUTPUT OP-TIONS if it has been previously installed.

Select in the program branch OUTPUT OPTIONS the chan-nel for which an analog output has to be activated. Press ENTER.


Press ENTER until CURRENT LOOP is displayed. Select YES to activate the output. Press ENTER.

Enter in ZERO-SCALE VAL. the lowest measured value expected. The unit of measurement of the source item will be displayed.

ZERO-SCALE VAL. is the measured value corresponding to the lower limit of the output range as defined in section 15.1.1.

Enter in FULL-SCALE VAL. the highest measured value expected.

FULL-SCALE VAL. is the measured value corresponding to the upper limit of the output range as defined in section 15.1.1.

example: The output range 4…20 mA was selected for a current loop, the zero-scale value was set to 0 m3/h and the full-scale value to 300 m3/h.

If the volume flow is 300 m3/h, a 20 mA signal is transmitted to the output. If the volume flow is 0 m3/h, a 4 mA signal is transmitted to the output.

15.4 Activation of a Pulse OutputA pulse output is an integrating output which emits a pulse when the volume or the mass of the medium which has passed the measuring point reaches a given value (PULSE VALUE). The integrated quantity is the selected physical quantity. Integration is restarted when a pulse is emitted.

The max. flow that the pulse output can work with will be displayed now. This value is cal-culated from entered pulse value and pulse width.

If the flow exceeds this value, the pulse output will not function properly. In this case, pulse value and pulse width should be adapted to the flow conditions. Press ENTER.

15.5 Activation of an Alarm Output

Max. 3 alarm outputs R1, R2, R3 per channel operating independently of each other can be configured.

Note! The menu item PULSE OUTPUT will be displayed in the program branch OUTPUT OPTIONS only if a pulse output has been installed.

Select in the program branch OUTPUT OPTIONS the chan-nel for which a pulse output has to be activated. Press EN-TER.


Select YES to activate the output. Press ENTER.

This error message will be displayed if the flow velocity is selected as physical quantity.

The use of the pulse output is not possible in this case as integration of the flow velocity does not result in a reason-able value.

Enter the PULSE VALUE. The unit of measurement will be displayed according to the current physical quantity.

When the totalized physical quantity reaches the pulse val-ue, a pulse will be emitted.

Enter the PULSE WIDTH. Values between 1 ms and 1000 ms will be accepted.

The range of possible pulse widths depends on the specifi-cations of the instrument (e.g. counter, PLC) to be con-nected with the pulse output.

Note! The menu item ALARM OUTPUT will be displayed in the program branch OUTPUT OPTIONS only if an alarm output is installed.

15.5.1 Alarm Properties

The switching condition, the holding behavior and the switching function can be defined for an alarm output:

A scroll list will be selected in the upper line with key . A list item will be selected in the lower line with .

Table 15.4: Alarm properties

alarm property setting descriptionFUNC(switching condition)

MAX The alarm will switch if the measured value exceeds the upper limit.

MIN The alarm will switch if the measured value falls be-low the lower limit.

+- -+ The alarm will switch if the flow direction changes (sign change of measured value).

QUANTITY The alarm will switch if totalizing is activated and the totalizer reaches the limit.

ERROR The alarm will switch if a measurement is not possible.

OFF The alarm is switched off.TYP(holding behavior)

NON-HOLD If the switching condition is not true anymore, the alarm returns to idle state after approx. 1 s.

HOLD The alarm remains activated even if the switching condition is not true anymore.

MODE(switching function)

NO CONT. The alarm is energized if the switching condition is true and de-energized when idle.

NC CONT. The alarm is de-energized if the switching condition is true and energized when idle.

Note! If no measurement is started, all alarms will be de-energized, inde-pendently of the programmed switching function.

Select in the program branch OUTPUT OPTIONS the chan-nel for which an alarm output has to be activated. Press ENTER.

display comparison

MAX measured value > limit

The alarm will switch if the measured value exceeds the limit.

MIN measured value < limit

The alarm will switch if the measured value falls below the limit.

example 1: upper limit = -10.0 m3/h

A measured value of e.g. -9.9 m3/h exceeds the limit. The alarm switches.

A measured value of e.g. -11.0 m3/h does not exceed the limit. The alarm does not switch.

example 1: lower limit = -10.0 m3/h

A measured value of e.g. -11.0 m3/h falls below the limit. The alarm switches.

A measured value of e.g. -9.9 m3/h does not fall below the limit. The alarm does not switch.

A positive limit will be compared to the totalizer value for the positive flow direction.

A negative limit will be compared to the totalizer value for the negative flow direction.

The comparison will also be made if the totalizer of the other flow direction is displayed.

15.5.3 Defining the Hysteresis

A hysteresis can be defined for alarm output R1 preventing a constant triggering of the alarm by measured values fluctuating marginally around the limit.

The hysteresis is a symmetrical range around the limit. The alarm will be activated if the measured values exceed the upper limit and deactivated if the measured values fall be-low the lower limit.

15.6 Behavior of the Alarm Outputs

15.6.1 Apparent Switching Delay

Measured values and totalizer values will be displayed rounded to two decimal places. The limits, however, will be compared to the non-rounded measured values. This might cause an apparent switching delay when the measured value changes marginally (less than two decimal places). In this case, the switching accuracy of the output is greater than the accuracy of the display.

Table 15.6: Limit of totalizer

switching condition

display comparison

QUANTITY totalizer limit

The alarm will switch if the totalizer reaches the limit.

Note! The unit of measurement of the limit corresponds to the unit of mea-surement of the selected physical quantity.

If the unit of measurement of the physical quantity is changed, the limit has to be converted and entered again.

example 1: physical quantity volume flow in m3/h, quantity limit = 1.0 m3

example 2: physical quantity volume flow in m3/h, lower limit = 60.0 m3/h

The unit of measurement of the physical quantity will be changed to m3/min. The new limit to be entered is 1.0 m3/min.

example: The limit is 30 m3/h and the hysteresis 1 m3/h. The alarm will be triggered for values > 30.5 m3/h and deactivated for values < 29.5 m3/h.

Enter the hysteresis or 0 (zero) to work without hysteresis. Press ENTER.

15.6.2 Reset and Initialization of the Alarms

After a cold start, all alarm outputs will be initialized. They will then be in the following state:

Press three times key CLR during measurement to set all alarm outputs to the idle state. Alarm outputs whose switching condition is still met will be activated again after 1 s. This function is used to reset alarm outputs of type HOLD if the switching conditions is not met anymore.

By pressing key BRK, the measurement will be stopped and the main menu selected. All alarm outputs will be de-energized, independently of the programmed idle state.

15.6.3 Alarm Outputs during Transducer Positioning

When the positioning of the transducers begins (bar graph display), all alarm outputs switch back to the programmed idle state.

If the bar graph is selected during measurement, all alarm outputs switch back to the pro-grammed idle state.

An alarm output of type HOLD being activated during the previous measurement remains in the idle state after transducer positioning if the switching condition is not met anymore.

Switching of the alarms into the idle state will not displayed.

15.6.4 Alarm Outputs during Measurement

An alarm output with switching condition MAX or MIN will be updated max. once per sec-ond to avoid humming (i.e. fluctuation of the measured values around the value of the switching condition).

An alarm output of type NON-HOLD will be activated if the switching condition is met. It will be deactivated if the switching condition is not met anymore. The alarm remains acti-vated min. 1 s even if the switching condition is met shorter.

Alarm outputs with switching condition QUANTITY will be activated when the limit is reached.

Alarm outputs with switching condition ERROR will be activated only after several unsuc-cessful measuring attempts. Therefore, typical short-term disturbances of the measure-ment (e.g. switching on of a pump) will not activate the alarm.

Alarm outputs with switching condition +- -+ and of type NON-HOLD will be activated with each change of the flow direction for approx. 1 s (see Fig. 15.2).

Fig. 15.2: Behavior of a relay when the flow direction changes

If there is an internal adaptation to changing measuring conditions, e.g. to a considerable rise of the medium temperature, the alarm will not switch. Alarm outputs with switching condition OFF will be set automatically to the switching function NO CONT.

15.6.5 Alarm State Indication

The alarm state can be displayed during measurement. This function is activated in SPE-CIAL FUNCTION\SYSTEM SETTINGS\DIALOGS/MENUS. The setting is cold start resis-tant.

16 Troubleshooting

16 TroubleshootingIf any problem appears which can not be solved with the help of this manual, contact our sales office giving a precise description of the problem. Specify the type, serial number and firmware version of the flowmeter.

Calibration

FLUXUS is a very reliable instrument. It is manufactured under strict quality control, us-ing modern production techniques. If installed as recommended in an appropriate loca-tion, used cautiously and taken care of conscientiously, no troubles should appear. The flowmeter has been calibrated at the factory and usually, a re-calibration of the flowmeter will not be necessary. A re-calibration is recommended if

• the contact surface of the transducers show visible wear or

• the transducers were used for a prolonged period at a high temperature (several months >130 °C for normal transducers or > 200 °C for high temperature transducers).

The flowmeter has to be sent to FLEXIM for recalibration under reference conditions.

The display does not work at all or always fails

Make sure that the correct voltage is available at the terminals. The voltage is indicated on the metal plate below the outer right terminal. If the power supply is ok, the transduc-ers or an internal component of the flowmeter are defective. Transducers and flowmeter have to be sent for repair to FLEXIM.

The message SYSTEM ERROR is displayed

Press BRK to return to the main menu.

If the message is displayed repeatedly, note the number in the lower line. Track down the situations when the error is displayed. Contact FLEXIM.

The flowmeter does not react when key BRK is pressed during measurement

A program code has been defined. Press key CLR and enter the program code.

The backlight of the display does not light, but all other functions are available

The backlight is defective. This problem has no influence on the other functions of the display. Send the flowmeter to FLEXIM for repair.

128 UMG80XV1-7EN 31.7.2009

16 Troubleshooting

Date and time are wrong, the measured values will be deleted when the flowmeter is switched off

The data backup battery has to be replaced. Send the flowmeter to FLEXIM.

An output does not work

Make sure that the outputs are configured correctly. Check the function of the output as described in section 15.1.3. If the output is defective, contact FLEXIM.

Measurement is impossible or the measured values substantially differ from the expected values

see section 16.1.

The totalizer values are wrong

see section 16.6.

16.1 Problems with the Measurement

A measurement is impossible as no signal is received. A question mark will be dis-played at the right side of the lower line

• Make sure that the entered parameters are correct, especially the outer pipe diameter, the pipe wall thickness and the sound velocity of the medium. (Typical errors: The cir-cumference or the radius was entered instead of the diameter. The inner pipe diameter was entered instead of the outer pipe diameter.)

• Make sure that the transducer recommended distance was adjusted when mounting the transducers.

• Make sure that an appropriate measuring point has been selected (see section 16.2).

• Try to obtain better acoustic contact between the pipe and the transducers (see section 16.3).

• Enter a lower value for the number of sound paths. The signal attenuation might be too high due to a high medium viscosity or of deposits on the inner pipe wall (see section 16.4).

The measuring signal is received but no measured values can be obtained

• An exclamation mark "!" right in the lower line indicates that the defined upper limit of the flow velocity is exceeded and, thus, the measured values will be marked invalid. The limit has to be adapted to the measuring conditions or the check has to be deacti-vated (see section 10.4).

• If no exclamation mark "!" is displayed, a measurement at the selected measuring point is not possible.

UMG80XV1-7EN 31.7.2009 129

16 Troubleshooting

Loss of signal during measurement

• If the pipe had been pressureless: Was there no measuring signal afterwards? Contact FLEXIM.

• Wait briefly until the acoustic contact is established again. The measurement can be prevented by a temporarily higher proportion of gas bubbles and solid particles in the medium.

The measured values substantially differ from the expected values

• Wrong measured values are often caused by false parameters. Make sure that the pa-rameters entered are correct for the measuring point.

• If the parameters are correct, see section 16.5 for the description of typical situations in which wrong measured values are obtained.

16.2 Correct Selection of the Measuring Point• Make sure that the recommended min. distance to any disturbance source is observed

(see Table 4.1 in chapter 4).

• Avoid locations where deposits are building in the pipe.

• Avoid measuring points in the vicinity of deformations and defects of the pipe and in the vicinity of welds.

• Measure the temperature at the measuring point and make sure that the transducers are appropriate for this temperature. Bubbles should be avoided (even bubble-free me-dia can form gas pockets when the medium expands, e.g. before pumps and after great cross-section extensions).

16.3 Maximum Acoustic ContactObserve the points in section 8.7.

16.4 Application Specific Problems

The entered sound velocity of the medium is wrong

The entered sound velocity will be used to calculate the transducer distance and, thus, is very important for the transducer positioning. The sound velocities programmed in the flowmeter only serve as orientation values.

Note! If the temperature fluctuates at the measuring point, it is important that the inner hook of the clasp grabs in the tension strip. Otherwise, the pressure of the transducer will be insufficient when the tempera-ture is low.

Note! It is recommended to use FLEXIM clasps with springs if the tempera-ture fluctuates strongly. Contact FLEXIM.

130 UMG80XV1-7EN 31.7.2009

16 Troubleshooting

The entered pipe roughness is not appropriate

Reconsider the entered value, taking into account the state of the pipe.

Measurements on porous pipe materials (e.g. concrete or cast iron) are only possi-ble under certain conditions

Contact FLEXIM.

The pipe liner may cause problems during measurement if it is not attached tightly to the inner pipe wall or consists of acoustically absorbing material

Try measuring on a liner free section of the pipe.

Higher proportions of droplets or solids in the medium scatter and absorb ultra-sound and therefore attenuate the measuring signal

A measurements is impossible if the value is 10 %. If the proportion is high, but < 10 %, a measurement might be possible under certain conditions.

16.5 High Measuring Deviations

The entered sound velocity of the medium is wrong

A wrong sound velocity can lead to the ultrasonic signal reflected on the pipe wall being mistaken for the measuring signal passing the medium. The flow calculated from the wrong signal by the flowmeter is very small or fluctuates around zero.

The defined upper limit of the flow velocity is too low

All measured flow velocities that are greater than the upper limit will be ignored and marked as invalid. All quantities derived from the flow velocity are marked as invalid, too. If several correct measured values are ignored, the totalizer values will be too low.

The entered cut-off flow is too high

All flow velocities below the cut-off flow are set to zero. All derived values are set to zero as well. The cut-off flow (default 2.5 cm/s) has to be set to a low value to be able to mea-sure at low flow velocities

The entered pipe roughness is inappropriate

The flow velocity to be measured is outside the measuring range of the flowmeter

The measuring point is not appropriate

Select another measuring point to check whether the results are better. The cross-sec-tion of the pipe is never perfectly circular, thus influences the flow profile. Change the transducer position according to the pipe deformation.

UMG80XV1-7EN 31.7.2009 131

16 Troubleshooting

The operating volume flow meets the expectations, but the standard volume flow deviates strongly.

The parameters for the measurement of the standard volume flow are not correctly en-tered (see section 13.4).

16.6 Problems with the Totalizers

The totalizer values are too high

See SPECIAL FUNCTION\SYSTEM SETTINGS\MEASURING\QUANTITY RECALL. If this menu item is activated, the totalizer values will be stored. The totalizer will take this value at the start of the next measurement.

The totalizer values are too low

One of the totalizers has reached the upper limit and has to be reset to zero manually.

The sum of the totalizers is not correct

See SPECIAL FUNCTION\SYSTEM SETTINGS\MEASURING\QUANT. WRAPPING. The output sum of both totalizers is not valid after the overflow (wrapping) of one of the total-izers.

C ReferenceThe following tables provide assistance for the user. The accuracy of the data depends on the composition, the temperature and the manufacturing process of the material. FLEXIM does not assume liability for any inaccuracies.

Table C.1: Sound Velocity of Selected Pipe and Lining Materials at 20 °C

The values of some of these materials are stored in the internal database of the flowme-ter. In column cflow, the sound velocity (longitudinal or transversal) used for flow mea-surement is indicated.

Take into consideration for the measuring task that the sound velocity depends on the composition and the manufacturing process of the material.

The sound velocity of alloys and cast materials strongly fluctuates. The values serve as an orientation only.
