2.1 General

1. Flow direction and meter position -

• Flow must always be in the direction of the arrow, bluff side of

vortex-shedding body facing incoming flow i.e. upstream side.

• Vertical pipe run: upward flow direction

• Horizontal pipe run: see below

3. Straight, unimpeded inlet and outlet runs

EXPANDER

REDUCER

Flexible pipes or bellows may be used before the upstream and after the downstream in case the vibrations are too high. Pipe vibration limit is

0.2 g peak to peak up to 8-500 Hz crossover frequency. (which equals

0.75 mm)

FLOW STRAIGHTENER

SPACIAL FLOW STRAIGHTENER

With flow straightener the inlet pipe length may be halved e.g. for a control valve the inlet length is 25D instead of 50D. The minimum inlet pipe length including flow straightener must always be 12 D. The small sizes (below 1" or DN 25) come with upstream & downstream pipelines & flange connections to suit customer's flanges.

4. Pipe vibration

Caused, for example, by the action of pumps, valves, etc., will falsify measurements particularly at low flow velocities. Support the pipeline on both sides of the flowmeter; in the direction perpendicular to both the pipeline & bluffbody axis.

SANDWICH VERSION

5. Pipeline along a wall

Where possible, the distance between the pipe centerline and wall should be greater than 0.5 m (20”). If it is less, first connect all cables to terminals in the connection compartment (power supply and outputs) and run them via an intermediate connection box (see also Section 3) before installing the flowmeter.

Do not lag (Thermally insulate) the meter body.

6. Orientation

• Turn the Display board through ±90 or 180 to obtain horizontal

positioning of the display.

• Turn the signal converter housing through ±900 or 1800 should that

be more suitable for the location of the installation.

7. State of Medium

• Ensure single-phase flow. Liquid droplets in gas / vapour, solid

particles in gas/liquid & gas bubbles in liquid are not permitted. In Liquid application e.g. water; to prevent cavitation, minimum D/S

pressure is given by the relation: Pds (bar_g) >= (2.9* DP)+ (1.3 * Ps) - 1.013 where DP= pr.drop of VFM in Bar from sizing

program.

Ps= Sat.pr.in Bar at op.temp

FLANGED VERSION

Page 6

• In case of steam or compressed gas, a moisture separator may be used

compensation

50D upstream of the meter if the dryness fraction is less than 95%.

• For gases, a filter or strainer may be used to remove solid particles.

This is specially important for meter sizes below 1".

2.2 Sandwich type to DIN 19205 / ANSI

flowmeter installation.

2.4 Temperature / Pressure measurement for External density

To measure the temperature and pressure of the medium for either mass flow/normalized f1ow computation using external flow computer or measure operating density using external pressure and temperature measurement (e.g. to feed the density value in the VFM off-line mass or normalized flow computation) suitable measuring points should

• Bolts, nuts and washers are supplied with meter, check flange

connection for leak-tightness after flowmeter installation.

Installation upstream of f1owmeter

Min. distance: 20*DN (DN = meter size) Installation downstream of flowmeter

Min. distance: 5*DN (DN = meter size)

Allowance must be made for the pressure drop in the flowmeter as correction value for operating conditions prevailing upstream of the flowmeter.

3. Electrical Connection

3.1 Installation Location & Cable diameter

Location

• Do not expose the compact flowmeter to direct sunlight Install a

sunshade if necessary.

• Do not expose to intense vibration. If necessary support the pipeline

to the left right of the flowmeter.

• The rotating design of the housing makes it easier to connect the two

cables for power and outputs to the terminals in the rear terminal box.

Cable diameter

• To conform to protection category requirements, observe

• the following recommendations :

• Cable diameter: 8 to 13 mm (0.31" to 0.51")

• Enlarge the inside diameter of the Screwed conduit entry by

removing the appropriate onion ring(s) from the seal, only if cables have extremely tight fit.

• Fit blanking plug PG16 and apply sealant to unused cable entries.

• Do not kink cables at conduit entries

• Provide water drip point (U bend in cable).

Conduit Installation, general wiring considerations

When electrical codes require conduit, it must be installed in such a manner that the meter connection compartment remains at all dry times.

3.2 Connection to loop power supply

• In case of functional extra low voltages (24VDC) protective

separation in conformity with VDE 400 part 410, or equivalent national standard, must be ensured.

• Hazardous area application will require the connection of

protective Earth.

• Connection to power, VFM 1091 K

• Current and frequency outputs are galvanically isolated when the

optional ground above is not used and can therefore be simultaneously connected to a receiver instrument which is grounded or separately connected to two receiver instruments.

• Ensure that 24V, 4-20 mA loop is grounded at one point only (i.e.

either at the input of the signal converter or at the input of the indicator, or at the output of the Power Supply). Do not ground the loop at more than one point.

4. Start-up

• Check that the system has been correctly installed as described in Sect. 1, 2 and 3.

• Before initial start-up check that the following details on the nameplate agree with the data specified in the report of settings for the signal

converter. If not, reprogramming will be necessary.

Meter size Fct3.1.1, Sect. 6.1, 6.2.5.

K-Factor Fct 3.1.2, Sect. 6.1, 6.2.5.

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

• Avoid abrupt changes in pressure in the pipeline.

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

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

“TEST” is displayed for approx. 3 seconds followed by “VFM 1091 ” the instrument type followed by “Ver x.xx” the software version of the instrument.

Then instrument operates in measurement mode where it displays the parameter being measured Or FATAL ERROR if there are one or more critical errors detected (For description on errors refer Sect. 5.5.)

Part B Signal Converter VFC 091

5. Opening of the signal converter

5.1 General

5.1.1 Starting up signal converter

When power is switched ON to signal converter it displays TEST, VFM, 1091 & Ver.x.x.x and then goes to measurement mode. In this initial sequence VFM 1091 (I) carries out self-diagnostics to check its own functiona1elements and loads the configuration data from non-volatile memory. If any error(s) are detected in power on diagnostics converter displays to carry normal measurements. The first measured parameter displayed is the one being displayed when power supply was removed last time.

5.1.2 Measurement Mode

In measurement mode, the parameters that converter measures/computes are shown on display in the appropriate units. (See Sect. 5.2 for display details). As per the configuration, display can be either in non- cyclic/cyclic mode. In non cyclic mode of display, use key to see the next parameter on display. In cyclic mode display shows all parameters one after another, wherein each parameter is displayed for about 6 seconds.

While in the measurement mode, the flow and the current values can be monitored using the HART values, the communicator also displays the minimum and maximum values of flow values, which are programmed into the device.

5.1.3 Programming or menu mode

All the configuration/settings/test functions are grouped in the form of menu having a tree structure (see Sect. 5.3.1 for details) and are accessible in the programming mode. Operator can view or alter the present settings, data values by the use of functions available in this mode. VFC091 implements all the universal commands and relevant common practice commands of HART parameters using HART All changes made in programming mode are stored in non-volatile memory and have appropriate effect on the operation of signal converter. While being programmed (i.e. while in the menu), the instrument will stop making further measurements and the current O/P will be frozen to the last value, pulse O/P will also stop. The changes made using the HART data to the device. After data is received, VFC091 updates the configuration n with thenewly received data. During the updation period, the measurement is interrupted. (The updation time is less than half second).

this enables you to program some of the main

Converter can detect errors during power-on diagnostics as well as when in normal measurement mode. Errors are put into two main categories viz. fatal errors and non-fatal errors. Fatal errors cause measurement to stop since they are serious in nature. Non-fatal errors do not affect functionality of the converter. If one or more errors are present, display (in measurement mode) starts blinking. If programmed so, error information is shown on display interleaved between display of two parameters.

5.4 Program organization & function keys

Function of keys in measurement mode:

After power-on, the signal converter enters the normal measuring mode. Display shows the actual measured value of the parameter, units and

arrow markers to identify parameter. A steady (non-blinking) display indicates that there are no errors in measuring mode. Use key to get the

next parameter on display. If display is in cyclic mode (Fct 1.2.6 CYCLE DISP as YES) the next parameter is displayed after every 6 seconds

and key has no function.

Use the key to go to the programming mode If Fct.3.2.1 ENTRY. CODE.1 is YES then converter will ask for the Code 1 password. Password

is the following sequence of 9 key operations Press key to go back to normal display.

Use the key results in prompt for Code 2 password. Code 2 password is predefined and reserved for Khrone Marshall service person.

Operator should not use key at normal display. If used by accident then give any arbitrary key sequence to code 2 prompt until display gets

back to normal.

6.2.4 Flow range and meter

Flow rate (min. flow to max. flow) which the flowmeter will be able to measure depends on the primary data (3.1.x functions) and application data (3.3.x functions). Thus, the flow range specified under the Fct. 1.1.2 MAX FLOW and Fct. 1.1.3 MIN. FLOW must be within the measuring range. Flow range for any given application is determined by sizing the meter for that application. If flow rate exceeds max. flow an error condition (HIGH FLOW) is generated. When the flow rate falls below the min. flow an error condition is generated. Vortex sensor signal l is weak at this condition LOW FLOW and if flow rate reduces further, vortex signal related errors such as NO SIGNAL, LOW FREQ. will occur.

Page 22

6.2.5 Primary information

Primary data gives VFC 091 the basic information about the vortex primary sensor. Use Fct. 3.1.1 NOMINAL.DIA for specification of the nominal DIN/ANSI size and Fct. 3.1.2 K-FACTOR for the calibration factor of the primary.

6.2.6 Application information

6.2.7 Internal Electronic Totalizer

- The internal electronic totalizer counts volume, normalized- volume or mass. Totalizer value is saved in the non-volatile memory upon

power failure. Totalizer can be displayed in the units desired as per the programming of Fct. 1.2.2 TOTAL. UNITS. Totalizer counting is interrupted for the duration of power failure. Counting may optionally be stopped and thereafter restarted by the use of Fct. 3.2.3 TOT. ON/OFF. Totaliser counting is also interrupted when in programming mode (in Menu)

- Resetting [to 0] of the totalizer is possible by using Fct. 3.2.2 TOT. RESET.

6.2.13 Functions through HHC

The special functions which are accessible only through HART

communicator include Device Information and

Multidrop Operation

DEVICE INFORMATION

This is used to identify the devices in the field. This is stored in the device and shown to you on request but has no effect on the functionality of the flowmeter. None of these parameters are used for computational purpose during the measurement. Manufacturer : This is a factory-programmed name. For VFM1091 (I) the manufacturer is KHRONE MARSHALL.

Tag : The maximum number of characters allowed for tag is eight. Tag can be

effectively used to distinguish between different flowmeters in the field.

Descriptor : This parameter provides 16 characters which can be used to store more

descriptive data of a flowmeter.

Message : This provides 32 characters. This may be used for identification or display

of other important information regarding the flowmeter.

Revision Numbers: These are factory programmed and cannot be changed by the user. Universal Rev - Gives the HART

Universal command revision which the flow meter should conform to. Transmitter Rev - Gives the revision for the device specific VFC091 model. Software Rev - Gives the internal software revision. Hardware Rev - Gives the revision number for the hardware. Final Assembly - Refers to the factory set value of the electronic assembly. Device ID - Gives unique identifier for transmitter.

MULTIDROP CONFIGURATION

In multidrop configuration, upto 15 flow meters can be connected to a single communications transmission line. If the device is configured for multidrop operation, the current output is parked to the minimum value (4mA) and the communication occurs digitally between the flowmeters and the control system. Since the speed of communication for HART

is not fast enough for control applications, update rate should be considered before multidroping the flowmeters. The other factors like the number of different models used the transmission line specifications, safety considerations etc. should also be taken into account. In multidrop mode, the control system/communicator identifies each of the devices by means of the polling address which can be programmed into the device.

POLL ADDRESS

This gives the identification number for the flowmeter in multidrop mode. The value of the number should be between 1 and 15. Please note that the flowmeter should be in loop mode while entering the poll address. Use Generic Online Menu 1,4, 3, 4, 1 to change the polling address of the meter.

Always switch-off power source before commencing work.

l. Use the special wrench to remove cover from

the electronic compartment. Ensure that screw threads of electronic compartment cover are well greased at all times.

2. Remove screws A and turn display board to one side.

3. Remove the piezo cable from the preamplifier board at location Z by its (and not by pulling cable itself!)

4. Do the following tests on the sensor cable

Capacitance between centre pin and each outer pin

Resistance between center pin and each outer pin >200M ohm. Also resistance between each sensor

7. Functional checks

wire pin and earth should be >200 M ohm. Also short out all three pins & measure resistance between these pins & Earth. This should be > 200 M W

5. Reassemble converter.

7. 1 Primary head functional checks

7. 2 Signal converter functional checks

7.2 Vortex Sensor

7. 2 .1 Self diagnostics

On power-on VFC 091 carries out diagnostic checks wherein the instrument checks its functional elements as far as possible. Diagnostic failure result in fatal errors and are indication of a hardware fault within electronics. Usually it is necessary to replace electronics in such cases.

7. 2 .2 Display check

Display functionality can be checked by the use of

Fct 2.1 TESTDISP.

This function flashes all the segments of the display.

Preamplifier

flat cable from CPU to Preamp board

Power supply board

Flat cable to display board

CPU board

7. 2 .3 Current output check

Fct.2.2 TEST I can be used to test current output function of VFC 091. With this function it is possible to generate following test values- between 4 and 20mA (integer values only) Current output electronics is factory calibrated and should be within +/- 0.02mA. Otherwise re-calibration of current output is necessary by KHRONE MARSHALL service person.

7. 2 .4 Pulse output check

Fct. 2.2 TEST P is meant for checking the pulse output

function with a power supply (24VDC) connected through a load of lk/1W to pulse output terminals 4.1 & 4.2, and the output level (high or low) monitored with a voltmeter.

7. 2 .5 Frequency measurement check

Disconnect the sensor cable from the electronics as indicated in section 7.1.1 and feed a signal (sine or square wave) to the sensor connector Z on the preamplifier board. The signal should be fed between the center pin and one of the outer pins of the connector Z. The value of frequency fed should be indicated on the display when frequency measurement is enabled. This can also be checked with the help of the VS1 or VS2 Vortex Simulator in place of the signal source. The amplitude of the signal l should be 50mVp-p and the frequency between 2Hz and a value

equal to Qmax (m/hr) x K-factor (Pulses/m) max

It is assumed in this section that flowmeter has already been installed. (for installation details refer Sect. 2+3) Following are some trouble shooting hints.

SYMPTOMS: Display is blank.

· DC Supply voltage (between term. 5/6) is not

available (voltage range 12-36 Vd.c).

· Supply connected with reverse polarity

Important: Ensure that the screw threads of the covers on the electronics and connection compartments are well greased at all times

· Electronics faulty

SYMPTOM: Current output is not proper.

· Check current output electronics (refer Sect.7.2.3)

· Check that current output loop resistance is less

than Rmax specified by Section 3.3.2

SYMPTOM: Pulse output is incorrect

· Check the Pulse output electronics (refer Sect.7.2.4)

· Check programming of pulse output. (Functions

Fct1.3.x )

· Check that pulse output is not overloaded. For load

ratings of pulse output refer Sect.3.3.3.

SYMPTOM: 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 of pipe and the axis

of bluff body.

SYMPTOM: Flowrate indicated is 0.0 even with flow in

the pipe.

· Vortex sensor cable disconnected or not properly

connected.

· Flow sensor faulty – some checks are given in

Sect.7.1.1

· Electronics faulty (preamplifier)

· Fct. 3.3.4 Gain too low: Set gain to value of 5 or greater &

check.

SYMPTOM: Fatal error 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 error persists contact Forbes Marshall service.

SYMPTOM: Display contrast is progressively Fading.

· Never expose display directly to the sunlight!

Install a sunshade if necessary.

SYMPTOM: Flow indicated responds to changes in flow

but indicated value does not correspond to actual flow rate.

8. Trouble shooting hints

· Check programming of Fct.3.1.2 K-Factor which should be same as on the nameplate.

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

· Gaskets at the meter are protruding into pipe bore. Gaskets must not project into effective cross- section of the pipe.

· 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.

· Vortex signal is falsified due to a bi-

hase medium. Bi-phase media are not permitted. Use a moisture separator for wet steam applications to remove moisture droplets from the steam. Use suitable filters in gas applications to remove solid particles from the flowing gas.

· Incorrect angular position of the meter Refer to Sect.2.1 (1) for allowable mounting positions.

· Insufficient upstream / downstream pipe lengths. Check that upstream / downstream pipe lengths are of correct minimum length as given in Sect.2. 1(3).

· Check the flow direction & direction of arrow on the primary!

Range limit Calculation for Gases

To obtain the operating density rx at the operating temperature and pressure the following equation is used

x = r n x Px x Tn

Pn Tx

r x , r n = density of the gas at normal & operating conditions respectively. Pn, Px = pressure of the gas in absolute units at normal operating conditions respectively. Tn, T x = temperature of the gas in Kelvin at normal & operating conditions respectively.

To obtain operating volumetric flow from normalized volumetric flow and vice-versa the following equation is used:

Qn = Qx x Px

x Tn

Pn Tx

where: Qn & Qx are normalized and operating volumetric flow rates respectively the ratio of compressibility factors is assumed to be equal to 1. The following operating data of the process medium must be known in order to calculate the measuring range

· Density r x of product at flowing conditions, in kg/m3

· Dynamic (absolute) viscosity of medium at flowing conditions, in mPA *s (or in centipoise)

· Maximum volumetric flowrate Q

max in m3/hr.

· Minimum volumetric flowrate Q

min in m3/hr.

· Refer to page 4 for dimension of meter inside diameter.

The following limits apply to operation

· Reynolds number at min flow, Re > 20000 for linear measurements.

· Minimum detectable flow velocity Vmin (See Page 36 Diagram IV)

· Maximum flow velocity

Vmax =135.7306/

(r op)...For sizes DN25 to 200(1”to 8”)

= 83.87146/

(r op)...For sizes DN10S to 20(3/8”S to 3/4”)

In both the cases,Vmax is clamped at 75m/s. For densities,at and above 50kg/m3, Vmin is fixed to 0.94192 m/s for all sizes

· Calculating Reynolds number

Re = 353. 67 Q min * (m3/h) * (kg/m3)

Range limit Calculation for Saturated Vapour

In the same way as for gases, use the above equations to establish the range limits for the volume flowrate. Refer to vapour tables for the appropriate density, and calculate the volume flowrate from the mass flowrate. Check the range limits if operating parameters change.

Measuring principle

The Vortex flowmeter is used for measuring the flow velocity of fluids in pipelines. The measuring principle is based on the development of a Karman Vortex shedding street in the wake of body built into the pipeline. In theory, this process enables measurements to be carried out in turbulent flows with a Reynolds number Re > 1091, but linear measurements are only possible where Re > 20 000.

The periodic shedding occurs first from the one side and then from the other side of a bluff body (Vortex- shedding body) installed perpendicular to the axis. Vortex shedding generates a so-called "Karman Vortex Street" with alternating pressure conditions whose frequency f is proportional to the flow velocity v. The non dimensional Strouhal number S (primary head constant) describes the relationship between vortex shedding frequency F. (in Hz), width b of the body and mean flow velocity v (in m/s)

F = S * v

b The flexural vibration of the vortex-shedding body is picked up in the primary head via sensors and analysed in the signal converter. In the case of 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 product pressure and temperature or product density at the installation location of the flowmeter must be known factors.
