1. Measuring Principle

The Vortex flowmeter is used for measuring the flow velocity of fluids in pipelines. The measuring principle is based on thedevelopment of a Karman Vortex shedding street in the wake of a body built into the pipeline. In theory, this process enablesmeasurements to be carried out in turbulent flows with a Reynolds number Re>3000, but linear measurements are onlypossible where Re>20,000.

The periodic shedding of eddies occurs first from one side and then from the other side of a bluff body (Vortex-shedding body)installed perpendicular to the pipe axis. Vortex shedding generates a so-called “Karman Vortex Street” with alternatingpressure conditions whose frequency F is proportional to the flow velocity V. The non-dimentional Strouhal number S (primaryhead constant) describes the relationship between Vortex shedding frequency F (in Hz) width b of the body, and mean flowvelocity v (m/s)

F = b

vS *

The flexural vibration of the Vortex-shedding body is picked up in the primary head via sensors and analysed in the signalconverter. In the case of the gaseous, flowing media, the vibration frequency ranges between 10 and 7000 Hz.

To permit the mass rate of flow to be calculated from the volume rate of flow, either the medium pressure and the temperatureor the medium density at the installation location of the flowmeter must be known factors.

2.1 Intended use

The vortex flowmeters manufactured by Forbes Marshall Pvt. Ltd. are used to

measure the flow of gases, vapors and liquids.

These flowmeters are particularly suitable for measuring:

• Clean liquids with low viscosity (< 10 cP)

• Hydrocarbons with low viscosity (< 10 cP)

• Water

• Chemicals with low corrosiveness

• Saturated steam

• Superheated steam, including CIP and SIP applications in the food industry

• Industrial gases

The meters are rated for the following flow velocities:

• From 0.3 to 9.0 m/s for liquids

• From 3.0 to 80 m/s for gases and vapors

Caution!

The operator shall bear sole responsibility for the use of the flowmeters in respect of suitability, intended use

and corrosion resistance of the materials used to the process product.

The manufacturer shall not be liable for any damage resulting from improper use or deployment contrary to

the prescribed purpose.

Do not use any abrasive or highly viscous media > 10 cP.

Note!

The sensors are fabricated from stainless steel 316 L DIN (1.4404).

In your project planning, please take account of the data given in the corrosion tables.

The pressure-loaded components have been designed and rated for stationary operation taking

account of maximum pressure and temperature.

External forces and moments, caused e.g. by pipe stresses, have not been taken into account.

Primarily, volumetric flow and temperature are measured, with pressure measurement as an

option. From these parameters the flowmeter calculates the mass flow or standard volumetric

flow using pre-programmed density data and then issues the measured values via various

communication interfaces.

2.13 Start-up

• Check that the system has been correctly installed as described in Sections 2.

• Before the initial start-up check that the following details on the name plate agree with the data specified in the report of

settings for the signal converter. If not, reprogramming will be necessary. Refer to Convertor manual.Meter size Fct. 3.1.1K-Factor Fct. 3.1.2

• The flowmeter is ready for service in 15 minutes (waiting time) after switching on the power source. Increase the flow velocityslowly and steadily.

• Avoid abrupt changes in pressure in the pipeline.

• If the process product is steam, condensate may form initially and cause faulty measurements when the system isstarted up for the first time.

• When powered, the signal converter normally operates in the measurement mode. The power-on sequence to themeasurement mode is as follows:

‘TEST’ is displayed for approx. 3 seconds followed by ‘VORTEX FLOW CONVERTER’ the instrument type followed by ‘VerX.Y.Z’ the software version of the instrument.

Then the instrument operates in the measurement mode where it displays the parameter being measured.

4. Operation of the signal convertor

4.1 General

4.1.1 Starting up signal convertor

When the power is switched ON to the signal convertor, it displays “TEST”, VFC XXX and “Ver X.Y.Z” and then goes to the

measurement mode. In this initial sequence, carries out self diagnostics to check the preamplifier section, sensor integrity

and then loads the configuration data from the non-voIatile memory.The first measured parameter displayed is the one being

displayed when the power supply was switched off the last time. It is possible to enter the programming mode by pressing the

key.

4.1.2 Measurement Mode

In the measurement mode, the parameters that the convertor measures/computes are shown on the display in the appropriate

units. As per the configuration, the display can be either in the non-cyclic/cyclic mode. In the non-cyclic mode of display, use

key to see the next parameter or error message on the display. In the cyclic mode, the display shows all the parameters

one after another, wherein each parameter/ error message is displayed for about 6 seconds.

4.1.3 Error Handling

The convertor can detect errors during the power-on diagnostics as well as when in the normal measurement mode.

If one or more errors are present, the vertical bar in the top left corner of the display (in the measurement mode) starts

blinking. If enabled, the error information is shown on the display interleaved between the display of two parameters. The first

line displays the total number of errors and the second line displays the error message. Refer to the list of Error Messages.

4.1.4 Programming or menu mode

All the configuration/settings/test functions in the form of a menu function x.x.x are accessible in the programming mode.

The operator can view or alter the present settings, data values by the use of functions available in this mode.

All changes made in the programming mode are stored in the non-volatile memory after exiting the menu and have appropriate

effect on the operation of the signal convertor. While being programmed (i.e. while in the menu), the instrument will stop

making further measurements and the current output will be frozen to the last value, the pulse output will also stop.

6.1.1 Program function description

The program functions are given in a numeric order as follows:

• Function number and title

• Description of the function

When you enter any numeric value in the floating point format, the accuracy of viewing any floating point value entered is +0.003% . The precision of the measured variable depends on the choice of precision (position of decimal point) while enteringthe operating value of that parameter.

Fct. 1.1.1 MEAS. INST. measuring instrument typeSet the instrument to measure the volumetric or thenormalized volumetric or the mass flow rate as per the options:

• VOLUME • NORM.VOLUME • MASS

Usually, this function is used once initially. If you need to change the basic measurement type later on, you should check/reprogram all the flow rate and the totalizer related functions such as -

• MAX.FLOW • MIN.FLOW • FLOW UNITS• TOTAL.UNITS • 4 mA FLOW • 20 mA FLOW• RANGE F • TOT. VALUE Fct. 1.1.2 MAX.FLOW maximum flow rate

Enter the maximum flow rate desired. The max. flow should be within the measuring range for the given primary data (3.1.xfunctions) and the application data (3.5.x functions).

The current output range (4-20 mA) corresponds to the 0% flow (Q0%) and the 100% flow (Q100%) respectively.

If the flow rate exceeds the MAX FLOW, an error HIGH FLOW is annunciated on the display with an error symbol flashing atthe top left corner.

The base units are m3/hr, nm3/hr and kg/hr respectively for Volume, Norm. Volume and Mass. For units other than thespecified units, replace the base unit with the user unit by changing the literal text. Also, enter the coefficient of that particularunit with respect to the basic unit depending on the measuring instrument type that you have selected.

Refer to the formula given:

User Unit *A1 coeff.+A0 offset = Base unit

Example: If the user unit is litre/hr

A1 coeff. = Base unit/ user unit = 1/1000 = 0.001

A0 offset = 0

Fct. 1.2.6 ERROR MSG. display of error messages Fct. 1.1.3 MIN. FLOW minimum flow rate

Enter the minimum flow rate in the same units as for the max.flow above. The min. flow should be within the measuring rangefor the given primary data (3.1.X functions) and the application data (3.5.X functions). If the flow is below the min. flow then anerror LOW FLOW is annunciated on the display with an error symbol flashing at the top left corner.

Note: This value cannot be zero for Vortex flowmeters. This value is normally set to the minimum flow rate (determined fromthe sizing) for the size of the primary used.

6/2

Fct. 1.1.4 TIMECONST. time constant for flow rate

Enter a low-pass filter time constant in seconds to be applied to the flow rate. A value of zero indicates that the low-pass filteris not to be applied. With this function, it is possible to compromise between a steady indication (on the display/currentoutput) and the response time (to flow changes). It should normally be within 0-20 sec. The factory set value is 2 sec. Youmay increase it if you observe abnormal fluctuations on display.

Fct. 1.2.6 ERROR MSG. display of error messages

Choose YES so that the error messages appear between the display of parameters in the normal measuring mode, otherwiseselect NO.

Fct. 1.2.7 CYCLE DISP. cyclic/non-cyclic display

YES means the display will cycle automatically. This means a measured parameter is shown in the selected units for about6 seconds and then the next parameter in the display cycle is shown for 6 seconds and so on. NO (non-cyclic display) meansthe parameter is continuously shown on the display (to see other parameters or to change setting use the key). You maysee error messages in between the changeover from one parameter to next if error(s) are present and Fct. 1.2.6 ERRORMSG. is YES.

Fct. 1.3.2 RANGE I current output range selection

Here one selects one of the three possible range options. To set the current output as 4-20 mA with/without an errorindication on the current output. When a range with a suffix of 22E or 3.55E is selected then it means that the current outputwill give 22 mA or 3.55 mA error output if any error(s) are present in the instrument. The range options are listed below:

• 4-20

• 4-20/22E • 4-20/3.55E

Fct. 1.4.1 FUNCTION P Pulse output

Choose YES to make the pulse output active. NO makes the pulse output inactive (0 Hz).

Limits: The max. frequency of the pulse output is 0.5 Hz. To ensure that the pulse output does not exceed 0.5 Hz at max.flow, the coefficient in totalizer units can be adjusted. The pulse output will be an exact replica of the integer value of theinternal totalizer. If the flow rate exceeds in such a way that the pulse rate exceeds 0.5 Hz then the pulse output will be erratic.

For Example:

For a flow rate of 360 kg/hr, pulses will be 360 pulses/hr. as the pulse output is exact replica of integer totalizer. So the freq.of the pulses will be 0.1 Hz. This is within given limits. But for flowrate of 3600 kg/hr., pulses will be 3600 pulses/hr. The freq.becomes 1 Hz. This is not within the specified limits. In this case, A1 coeffecient should be adjusted in func. 3.2.5 Tot. value.This should be selected such that the freq. of the pulse o/p lies below .5 Hz. If this factor is selected as 0.1 then the frequencyof the pulse output will become 10 times less. i.e. 0.1 Hz. which lies in given limits. Please note that the same factor will getapplied to Integer totalizer also.

Fct. 2.1.2 TEST I current output test

Caution: During this test, the current output will change to the test values so appropriate actions should be taken dependingon how the current output is used.

• 4 mA • 8 mA • 12 mA

• 16 mA • 20 mA

Place the current meter in series with the current loop. Selecting any value given above will cause that current to flow so thatyou can check it on the meter. Select CONT. YES to test other current values or CONT.NO to end. When the menu functionfinishes, the normal current value depending on the flow rate and the programming of the current output function will berestored.

6/3

Fct. 2.1.3 TEST P pulse output testCaution: When this test is initiated, the pulse output will run at the repetitive rate of 0.5003 Hz. So, appropriate actionsshould be taken depending on how the pulse output is used.

When the menu function finishes, the normal frequency value depending on the flow rate and the programming of thefrequency output functions will be restored.

Connect the electromechanical counter to the pulse output. (Refer to the connection diagram.) Select CONT.YES to test thefrequency value or CONT.NO to end. Selecting CONT.YES, will cause the pulse output to run at 0.5003 Hz.

6.1.2 VFC with FAD meter

An air compressor sucks in air from the atmosphere and delivers it compressed to the required pressure. Since the atmosphericair contains water vapor, what the compressor actually sucks in is a mixture of air and water vapour. Under thse conditions theFree Air Delivery specification of the compressor is not directly and easily known. Almost all manufacturers specify FAD atstandard suction conditions only. What the user gets to use as eventual plant air or process air needs to be found out and,hence, metered with ease and a reasonable accuracy of at least +1%.

VFM FAD-METER can measure FAD online, compensated for humidity and RPM apart from its use as STD FLOWMETER.The software built into the meter evaluates the FAD automatically online. The menu-driven user-friendly software prompts theuser for information like the pressure and relative humidity, design and actual RPM, and the discharge pressure. The steamtables and the compressibility data are programmed into the memory as a standard feature. The meter is also available withan optional pressure sensor which measures the discharge pressure online eliminating the need to feed in the value manually.

YES means the display will cycle automatically. This means a measured parameter is shown in the selected units for about6 seconds and then the next parameter in the display cycle is shown for 6 seconds and so on. NO (non-cyclic display) meansthe parameter is continuously shown on the display (to see other parameters or to change setting use the key).

6/11

Fct. 1.4.1 FUNCTION P Pulse output

Choose YES to make the pulse output active. NO makes the pulse output inactive (0 Hz).Limits: The max. frequency of the pulse output is 0.5 Hz. To ensure that the pulse output does not exceed 0.5 Hz at max.flow, the coefficient in totalizer units can be adjusted. The pulse output will be an exact replica of the integer value of theinternal totalizer. If the flow rate exceeds in such a way that the pulse rate exceeds 0.5 Hz then the pulse output will be erratic.

For Example:For a flow rate of 360 kg/hr, pulses will be 360 pulses/hr. as the pulse output is exact replica of integer totalizer. So the freq.of the pulses will be 0.1 Hz. This is within given limits. But for flowrate of 3600 kg/hr., pulses will be 3600 pulses/hr. The freq.becomes 1 Hz. This is not within the specified limits. In this case, A1 coeffecient should be adjusted in func. 3.2.5 Tot. value.This should be selected such that the freq. of the pulse o/p lies below .5 Hz. If this factor is selected as 0.1 then the frequencyof the pulse output will become 10 times less. i.e. 0.1 Hz. which lies in given limits. Please note that the same factor will getapplied to Integer totalizer also.

Fct. 1.1.3 MIN. FLOW minimum flow rate








YES means the display will cycle automatically. This means a measured parameter is shown in the selected units for about6 seconds and then the next parameter in the display cycle is shown for 6 seconds and so on. NO (non-cyclic display) meansthe parameter is continuously shown on the display (to see other parameters or to change setting use the key). You may seeerror messages in between the changeover from one parameter to next if error(s) are present and Fct. 1.2.6 ERROR MSG.is YES.


Here one selects one of the three possible range options. To set the current output as 0-20 mA or 4-20 mA with/without anerror indication on the current output. When a range with a suffix of 22E or 3.55E is selected then it means that the currentoutput will give 22 mA or 3.55 mA error output if any error(s) are present in the instrument. The range options are listedbelow:• 4-20 • 4-20/22E • 4-20/3.55E

6/20

fct 1.3.5. VARIABLE I is NET POWER.

Fct. 1.4.1 FUNCTION P Pulse outputChoose YES to make the pulse output active. NO makes the pulse output inactive (0 Hz).

Limits: The max. frequency of the pulse output is 0.5 Hz. To ensure that the pulse output does not exceed 0.5 Hz at max.flow, the coefficient in totalizer units can be adjusted. The pulse output will be an exact replica of the integer value of theinternal totalizer. If the flow rate exceeds in such a way that the pulse rate exceeds 0.5 Hz then the pulse output will beerratic.

For Example:

For a flow rate of 360 kg/hr, pulses will be 360 pulses/hr. as the pulse output is exact replica of integer totalizer. So the freq.of the pulses will be 0.1 Hz. This is within given limits. But for flowrate of 3600 kg/hr., pulses will be 3600 pulses/hr. The freq.becomes 1 Hz. This is not within the specified limits. In this case, A1 coeffecient should be adjusted in func. 3.2.5 Tot. value.This should be selected such that the freq. of the pulse o/p lies below .5 Hz. If this factor is selected as 0.1 then thefrequency of the pulse output will become 10 times less. i.e. 0.1 Hz. which lies in given limits. Please note that the samefactor will get applied to Integer totalizer also.

Fct. 1.4.4 VARIABLE PAssign pulse output to either of following options

• FLOW • NET ENERGYFct. 2.1.2 TEST I current output test

6.3.2 VFC with Net Heat Meter

VFM supports net thermal power and net energy calculations for water. Thermal power is calculated online from the mass flowand the specific enthalpy both at the inlet of the process and at the outlet. The difference between these two values is the netthermal power. The net thermal energy is calculated by time integrating (totalizing) the net thermal power. The mass flow ismeasured by the VFM along with the temperature at that point. The temperature at the exit of the process is also measuredand transmitted (4 to 20 mA) to the VFM through an additional junction box. The mass flow rate at the inlet and the outlet ofthe process is assumed to be the same.

The net thermal power can be displayed in any one of the following units:

KJ/hr, MJ/hr, GJ/hr, BTU/hr, kCal/hr, KW, MW, TR.

The net thermal energy units may be displayed in one of the following units:KJ, MJ, GJ, BTU, kCal, KWH, MWH

For both thermal power and energy user defined unit can be set. For details see sect 3.1.1

For external temperature sensing, a 2-wire RTD transmitter can be used. This should have a current output 4 to 20mA andan accuracy better than + 0.25% of the full scale.

7.2 Display

Organization: The display consists of the following two fields.

Field 1: 10-character, 5x7 dot matrix alphanumeric display used primarily for showing numeric values and also for messages.

Field 2: 10-character, 5x7 dot matrix alphanumeric display used for showing units, messages, etc.

Programming: The measurement mode settings are as follows:

- To allow the selection of the units for all the measured parametersRefer to Fct. 1.1.2, 3.2.5, 3.5.4 and 3.5.5

- Select display mode (cyclic/non-cyclic) and the error messages to/not to appear in the display cycle.Refer to Sect. Fct. 1.2.6 to 1.2.7

Measurement mode: The display shows the measured parameter(s) in its selected unit. The parameter is displayedcontinuously in the non-cyclic mode. [Fct. 1.2.7]. To select other parameter(s) of the display cycle, if any, use the key. Inthe cyclic mode, all the parameters selected in the display cycle are displayed in a sequence one after another every 6seconds.

Programming mode: The numeric line indicates the menu/functions level such as Fct. 1.1.1 [current menu level digitblinks] and the alpha-numeric line indicates the menu/function title such as MEAS_INST.

Error indications: A blinking bar at the upper left corner in the measurement mode indicates that error(s) are present. Errormessages are displayed interleaved between changing from one display parameter to another, if Fct. 1.2.6 ERROR.MSG isYES. For description of the error messages, refer to Sect. 4.1.5.

7.3 Flow range and meter size

The flow rate (min. flow to max. flow) that the flowmeter will be able to measure depends on the primary data (3.1.x functions)and the application data (3.5.x functions). Thus, the flow range specified under the Fct. 1.1.2 MAX. FLOW and Fct. 1.1.3MIN. FLOW must be within the measuring range.

The flow range for any given application is determined by the sizing of the meter for that application.

When the flow rate exceeds the max flow, an error condition -HIGH FLOW- is generated. When the flow rate falls below themin. flow, an error condition -LOW FLOW- is generated. The Vortex sensor signal is weak at this condition and if the flowrate reduces further, Vortex signal related errors such as CHECK INST., LOW SIGNAL will occur.

7.4 Primary information

The primary data gives VORTEX FLOW METER the basic information about the Vortex primary sensor. Use Fct. 3.1.1NOMINAL.DIA for specification of the nominal DN/ANSI size and Fct. 3.1.2 K-FACTOR for the calibration factor of theprimary.

Depending on whether the primary has temperature sensor, the settings need be done inFct. 3.6.1 T-SENSOR. These sensors enable the VORTEX FLOW METER to provide an online T compensation.

Depending on whether the primary has Pressure Sensor, the settings need be done in Fct. 3.6.2 P-SENSOR. Thesesensors enable the VORTEX FLOW METER to provide an online P compensation.

7/3

7.5 Application information

This is the data of the process medium, its operating conditions and physical properties. It consists of:

– Process medium Fct. 3.5.1 FLUID and Fct. 3.5.2 MEDIUM

– Operating temperature and pressure conditions. Refer Fct. 3.5.6 TEMP. OPR and Fct. 3.5.7 PRES. OPR.

– Density of the medium at the operating conditions. This is required only if the software within the instrumentdoes not support the medium (Fct. 3.5.1 is selected as OTHER GAS OR OTHER LIQUID). Refer to

Fct. 3.5.6 DENS.OPR.

– Normal or reference P&T values required for normalized flow measurements only (depending on Fct.1.1.1).

The usual values are temp.norm = 0oC or 20oC and pres.norm = 1 atm.

– Density under normal conditions. This is required only for normalized volumetric flow and if the softwarewithin the

instrument does not support the medium (Fct. 3.5.2 is selected as OTHER GAS OR OTHER LIQUID).Refer to Fct. 3.5.9 DENS.NORM.

Not all of the above data needs to be given for any given application. Only the relevant data should bepunched during the actual programming.

7.6 Internal Electronic Totalizer

– The internal electronic totalizer counts volume, normalized volume or mass. The totalizer value is saved inthe non-volatile memory continuously. The totalizer can be displayed in the unit desired as per the programmingof Fct. 3.2.5 TOT.VAL. The totalizer counting is interrupted for the duration of a power failure. Counting mayoptionally be stopped and thereafter restarted by the use of Fct. 3.2.6 TOT. ON/OFF

– Resetting [to 0] or presetting of the totalizer is possible by using Fct. 3.2.5 TOT. VALUE.

7.7 Current (analog) output I

The current output gives an analog representation of the flow rate. An output of 20 mA always corresponds to Q100% and thatof 4 mA to Q0%. The current output between Q0% & Qmin is 4 mA.

FOR Qmin Programmed > = Qmin from Sizing

TESTING OF CURRENT OUTPUT IFct. 2.2 TEST I can be used to check the current output. Integer values between 4 and 20 mA are possible to be monitoredon a current meter. During the test, the current output changes to the test value(s). The normal current value is restoredautomatically (as per programming of the current output) when the measurement mode is resumed.

7.8 Pulse output P

The pulse output value is an exact replica of the internal integer totalizer. Every time the totalizer is incremented by one, thepulse output will give a pulse. For programming of the pulse rate, set the coefficient in Fct.3.2.5 TOT.VAL.

The pulse output is generated by tracking the totalized flow and, thus, provides a true reflection of the internal totalizer value.The totalizer value is saved, continuously.

7.9 Coding desired for entry into programming mode

Fct. 3.2.2 ENTRY.CODE.1 set to YES for the coding. The entry code consists of 9 key strokes of 3 keys in the givensequence, Refer to Section 3.2.1, functionality of the keys.

7.10 Behavior of outputs during programming

Programming of the VORTEX FLOW METER is “offline” meaning that the instrument stops working when it is in the programmingmode. This means that the VORTEX FLOW METER will stop measuring the flow rate and temperature; the totalizing flow andthe control outputs (current and pulse) as per the programmed configuration. Thus, this means that the VORTEX FLOWMETER will keep the totalizer value and the current pulse output as per the last value before entering into the programmingmode.

EXCEPTION: Test functions TEST I and TEST P will affect the current and the pulse outputs respectively only for theduration of the testing.

10. Function Checks

This section describes some functional checks that can be performed without using any special equipment. It must benoted that these checks are very preliminary and do not check the total functionality of the primary head or the signalconverter.

10.1 Current output check

Fct. 2.1.2 TEST I can be used to test the current output function of VORTEX FLOW CONVERTER. With thisfunction, it is possible to generate following test values: 0/2/4/10/20/22 mA. Refer to section 1.2 for the connectiondiagram.

The current output electronics is factory-calibrated and should be within + 0.02 mA. Otherwise re-calibration ofthe current output is necessary by Forbes Marshall Service.

10.2 Pulse output check

Fct. 2.1.3 TEST P is meant for checking the pulse output. 0.50607 Hz will be generated at pulse output. This canbe checked by connecting the electromechanical counter between the pulse output terminals.

10/1

10/2

10.3 Primary head functional checks

10.3.1 Vortex sensor

To perform the preliminary testing of the Vortex piezo sensor, the signal cable of the piezo sensor should be disconnectedfrom the signal converter electronics. To do this: always switch OFF the power source before commencing work!

1. remove the cover from the electronic compartment. Ensure that the screw threads of the electronic compartment coverare well greased at all times!

Do the following tests

Capacitance between the centre pin and each outer pin is from 3 nano farad to 9.52 nano farad

Resistance between the centre pin and each outer pin >200 M ohm. Also, the resistance betweeneach sensor wire pin and the earth should be >200 M ohm.5. Reassemble the converter in the reverse order

Temp Sensor I/P

Pressure sensor I/P

Piezo sensor I/p

Connector fordisplay

10.3.2 Temperature sensor

The PT-1000 temperature sensor can be checked by measuring its resistance.

Always switch OFF power source beforecommencing work!

Follow the steps 1 and 2 i.e. the same as in the above

3. Remove the temperature sensor cable at the location Y of the preamplifier board. Pull the cable by its end connector andnot by the cable itself!

4. Resistance between the 2 pins should be within 1K [0ºC] – 1.193k [50ºC] depending on the ambient temperature. Forother temperatures resistance values as per DIN43760.

5. Reassemble the converter in the reverse order.

11. Trouble-shooting

It is assumed in this section that the convertor has already been installed. (for installation details, refer to Sections2 and 3 in the Sensor Manual).

Given below are some trouble-shooting hints.

SYMPTOM: The display is blank.

• Supply voltage (between terminals 1/2) is not available.

• Electronics faulty

SYMPTOM: The current output is not correct.

• Check the current output electronics (refer to Sect.7.7)

• Check that the current output loop is not overloaded [1200 ohm max.]

SYMPTOM: The pulse output is incorrect.

• Check the pulse output electronics (refer to Sect. 7.8)

• Check the programming of the pulse output (Functions Fct. 1.4.1.)

• Check that the pulse output is not overloaded. For load ratings of the pulse output, refer to specifications on Page 3/2

SYMPTOM: INV.CONFIG (invalid configuration)

• Configuration data in the non-volatile memory is inadvertently corrupted. Go to the programming mode and recheck

(reprogram, if necessary) all the settings. If the error persists contact Forbes Marshall Service.

SYMPTOM: Display contrast is progressively fading.

• Never expose the display directly to the sunlight! Install a sunshade if necessary.

11/1

11.1 Trouble-shooting hints

It is assumed in this section that the flowmeter has already been installed. (for installation details, refer to Sections 2 and 3).

Given below are some trouble-shooting hints.

SYMPTOM: A non-zero flow indicated when no actual flow in the pipe.• Mains interference due to improper earthing.

The protective earth PE terminal should be properly grounded.

• Excessive mechanical vibration in the pipe. If so, support the pipeline near the flowmeter perpendicular to both the axis ofthe pipe and the axis of the bluff body.

• This problem can be solved by reducing the factory set gain.

For e.g. Factory set gain for Gas/Steam is 11 and for liquid it is 3. This can be reduced to 6 for Gas/Steam and 2 for liquid.

Caution: By reducing the gain, the minimum measurable flow rate will go up by the factor which is approx. equal to squareroot of ratio of the gains. (old gains/ new gain). If the min. flow with reduced gain is above the min. flow which is required tobe measured, then reducing the gain is not the permanent solution. Then the installation should be corrected and also thevibrations should be eliminated.

SYMPTOM: ‘CHECK INST.’ error is displayed when no flow in the pipe.

The display should normally indicate 0.0 flow rate, LOW FLOW and LOW SIGNAL errors when there is no flow in the pipe.The additional CHECK INSTALL error (flow rate = 0.0 or some steady or fluctuating value) is an indication of:

• Improper/inadequate earthing

• Excessive pipe vibration

SYMPTOM: Flow rate indicated is 0.0 even with flow in the pipe.

• The Vortex sensor cable disconnected or is not properly connected.

• Flow sensor faulty – some checks are given inSect. 10.1

SYMPTOM: The flow indicated responds to changes in the flow but the indicated value does not correspond tothe actual flow rate. Also ‘CHECK INST.’ error may appear intermittantly.

• Check the programming of Fct. 3.1.2 K-Factor which should be same as that on the name plate

• The meter is not properly centered on the pipeline. The axis of the meter bore should be aligned with that of the pipe.

• Gaskets at the meter are protruding into the pipe bore. The gaskets must not project into the effective cross-section of thepipe.

• Irregularities on the surface of the pipe bore. The pipe bore should be free from irregularities at the welded joints, dirt,deposits and excessive surface roughness.

• The Vortex signal is falsified due to a bi-phase medium. Bi-phase media are not permitted. Use a moisture separator for wetsteam applications to remove the moisture droplets from the steam. Use suitable filters in gas applications to remove solidparticles from the flowing gas.

• Incorrect angular position of the meter.Refer to Sect. 2.10 for the allowable mounting positions.

• Insufficient upstream/downstream pipe lengths. Check that the upstream/downstream pipe lengths are of the correctminimum length as given in Sect. 2.11.

• Check the flow direction and the direction of the arrow on the primary.

Addendum to Installation and Operating Instructions

Precautions for “Safe and Desired” operation of VFS 8000with VFC 700 signal converter

Do

Ensure that sufficient Upstream and Downstream straight lengths are provided

Check that the housing of the primary head is perfectly centred between the process flanges

Provide proper supports to the pipeline at both ends of the meter to keep the pipe vibration level wellbelow the maximum limit specified

Ensure that the unit is installed in the process pipeline with fasteners securely and firmly tightenedcausing no leakage of the process fluid through the gaskets

Check the chemical compatibility of the material of the wetted parts with the process fluid

Maintain proper Downstream pressure to avoid cavitation

Degrease the meter properly in case the process fluid is hazardous like Oxygen

Ensure that the controlled valve is opened slowly not allowing the start-up velocity from being veryhigh in case the process fluid is hazardous like Oxygen

DO NOT

Use the meter with the process fluid being bi-phase like Gases-Vapours with liquid droplets or solidparticles and gas bubbles in liquids

Install the meter where the process medium is pulsating with fluctuations in the process pressure Allow any of the parameters like Flow-Density-Pressure-Temperature- Reynolds Number beyond the

limit value specified for the meter on the Nameplate and the Test and Guarantee Certificate Tamper with any parts of the primary head of the meter Replace the fasteners with any other make or brand without the consent of the manufacturer Allow the process pressure to exceed the flange rating.
