Please read the Handbook before installing the meter. Many problems are avoided when the simple guidelines in this handbook are followed.

Installation and Operating Instructions OPTIMASS

1 Mechanical Installation

1.1 General principles

The OPTIMASS mass flow meters provide high accuracy and excellent repeatability. Narrow band pass digital filtering, and the mathematically modelled internal primary head design with AST (Adaptive Sensor Technology) for the OPTIMASS sensor family provide exceptional immunity to external vibratory disturbances from nearby process equipment. The accuracy of the flow meter is not affected by velocity profile.

The following installation guidelines are practical to implement, particularly if planned before the OPTIMASS meter is first installed. For further dimensions or connections, please refer to the relevant section.

For the OPTIMASS, in general, no special mounting requirements are necessary. However, good general engineering practice for the installation of flow meters should still be observed.

The general guidelines described in this section are valid for the complete OPTIMASS family of mass flow meters.

• The mass flow meters do not require any straight inlet or outlet runs.

• Due to the weight of the meters we recommend the use of supports.

• It is permissible to support the body of the meter.

• The meter can be installed horizontally, in an upward sloping pipeline or vertically. For best results, a

vertical installation with flow in an upward direction is recommended.

This label on the meter shows the flow direction programmed into the converter in function 3.1.4. As default this is always in the direction of the ‘+’ arrow, i.e. left-to right as the label is viewed.

Installation and Operating Instructions OPTIMASS

Examples

Vertical mounting Horizontal mounting

Upward sloping installation

Avoid mounting the meter with long vertical drops after the meter. This could cause siphoning and cause measurement errors.

Avoid mounting the meter at the highest point in the pipeline. Air or gas can accumulate here and cause faulty measurements

Flow

1 Valve for zeroing flow meter 2 The second valve is recommended if the pump is switched off to prevent reverse flow

To enable a good zero to be done, it is recommended that a shut-off valve be installed downstream of the flow meter.

Installation and Operating Instructions OPTIMASS

1.1.1 Transport and Lifting

As the larger meters are heavy, care should be taken when lifting to install.

• Meters should be lifted or suspended using a well maintained sling.

• The meters should under no circumstances be lifted by the electronics housings.

• The meters can be lifted and suspended from the spigots as shown.

Installation and Operating Instructions OPTIMASS

1.2 OPTIMASS 7000 Single Straight Tube Meter

1.2.1 Specific Installation Guidelines

• Tighten flange bolts evenly.

• Observe min and max pipe end loads at end of this section.

The use of reducers at the flanges is allowed. Extreme pipe size reductions should be avoided due to possibility of

cavitation and degassing.

There are no additional installation requirements for the OPTIMASS 7000 sensors. Fixing of flexible hoses directly on the meter is allowed.

1.2.2 Ambient / Process temperatures

The specified and approved ambient and process temperatures must be observed.

Note:

Where meters are mounted in direct sunlight, it is recommended to install a sunshade. This is particularly important in countries with high ambient temperatures.

The maximum differential temperature between the process and ambient temperature without insulation is 130°C or 265°F for Titanium and 80°C or 115°F for Hastelloy and Stainless Steel meters.

1.2.3 Pressure Equipment Directive (PED) requirements.

To comply with the requirements of the PED in Europe, the following information is provided to assist the plant engineer in installing the meter.

Installation and Operating Instructions OPTIMASS

1.2.4 Secondary Pressure containment

The OPTIMASS 7000 meters are supplied with secondary pressure containment as standard.

Allowable maximum secondary containment pressures are 63 bar at 20°C or 914 psig at 70°F

If the user suspects that the primary tube has failed, the unit must be depressurised and removed from service as soon as possible.

Note:

In the 7000 Series there are high pressure feed through seals and ‘O’ rings that might not be compatible with the process fluid for an extended period if a primary tube fails. It is important to remove the meter ASAP

It is the user’s responsibility to ensure that the materials used are compatible with this product. Other ‘O’ ring materials are available on request.

1.2.5 Pressure de-rating

Meter data plates are stamped with maximum pressure rating (at max. operating temperature) of connection, primary tube or secondary pressure containment (whichever is the lower). Higher pressures may be possible at lower temperatures.

Titanium Tubes and secondary pressure containment is 63 bar at 20°C or 910 psi at

4°F

De-rated to 40 bar at 150°C or 580 psi at

300°F

The titanium tubes could handle a higher pressure, but where this exceeds the pressure rating, a relief or bursting disk has to be fitted to the secondary pressure containment. This can be done as a special. (This is available for meter sizes up to 25 only)

Hastelloy and SS measuring tubes are rated for 50 bar at 20°C or 725 psi at

Loads given in both tables are maximum static loads. If loads are cycling, particularly between tension and compression then these loads should be reduced. Please consult KROHNE for more information.

Installation and Operating Instructions OPTIMASS

1.2.6 Hygienic Applications

The OPTIMASS 7000 series is available with a variety of hygienic process connectors.

When using / installing meters with hygienic process connectors, care should be taken to ensure the meter is well supported / clamped, as the meters are heavy and could injure when disconnected from the adjacent pipe work. The recommended method of installation is to mount the meter against a support / wall with the body of the meter supported / clamped. The process pipe work can then be supported off the meter. The meter is too heavy to be supported from the thin walled piping usually associated with the hygienic industry.

Meter supported from its body

Installation lengths

For installation lengths, please see section 1.2.10

Please check with KROHNE if you are unsure of the installation length. Many meters are built to customer requirements / specifications especially where special hygienic process connectors have been adapted to the meter. As these are normally non-standard, the installation length will not be given in the technical data.

It is also recommended that the seals be replaced regularly to maintain the hygienic integrity of the

connection.

Version Titanium Meter SS 318 Meter

All welded DIN 11864

Titanium Grade 2 SS 318 All welded Tri-Clamps Adaptor versions 316L Stainless Steel 316L Stainless Steel EPDM seals EPDM seals

Unless specifically requested, internal surfaces are not polished and no warranty is made as to the surface finish. If polishing option and /or EHEDG, ASME Bio-Processing or 3A approvals was selected at time of order, all product contact surfaces are polished 0.5 micrometer Ra (Ra 20) finish or better.

Use of OPTIMASS 7000 SS sensors above 100°C – Hygienic Connections only

Sizes 25S, 40S, 50S and 80S sensors with hygienic connections may be exposed to temperatures above 100°C up to a maximum of 130°C for a maximum of 2 hours (e.g. for steam cleaning purposes). The maximum temperature shock permitted either from cold to hot or from hot to cold is 110°C.

E.g. A meter measuring a product at 20°C can be immediately steam cleaned at 130°C, but a meter measuring a product at 5°C can only be immediately steam cleaned at 115°C. Conversely, after steam cleaning at 130°C the minimum allowed temperature of the product introduced immediately afterwards is 20°C.

Operation outside of these guidelines may cause shifts in the mass flow and density calibration. Repeated shocking may also cause premature failure of the meter.

Installation and Operating Instructions OPTIMASS

1.2.7 Heating and insulation

There are several methods to heat the meter. In most cases heating is unnecessary as the meter is designed as such that very little heat is lost or gained through the outer cylinder.

Insulation

Where insulation is required a variety of materials may be used to insulate the meter. Care must be taken not to insulate the meter above the halfway mark of the electronics support post as shown in the sketch.

Do not insulate above this line.

Insulation

Electrical Heating

Electrical tape heating may be used. Care should be taken to only heat the sections where the best effect will be achieved. Do not heat above the converter mount centre line as shown above. The following guidelines must be observed.

Areas A and B may be heated. Area C must not be

heated.

When insulating please observe guidelines as per insulation section.

Installation and Operating Instructions OPTIMASS

Liquid / Steam heating jacket

The meter can be supplied with a heating jacket. This jacket is designed to minimise the differential stress across the meter where differences in temperature between outer cylinder and measuring tube exist.

The connections to the heating jacket are NPT or Ermeto sockets.

It is recommended that reinforced flexible hoses be used to connect the heating jacket to the heat source.

Important:

Always heat jacket to working temperature before flowing product in measuring tube.

It is important to avoid the use in the heating jackets of fluids which cause crevice corrosion.

Regarding jacket materials. Although all the jacket materials are 316L, the outer cylinders are 304L (Optional 316L). Connections should be made to ensure all air can be vented on liquid systems and all condensate can be drained on steam systems.

Note :

Max heating medium pressure and temperature for heating jackets is 10 bar at 150°C or 145 psig at 300°F for titanium measuring tubes and 10 bar at 100°C or 145 psig at 210 °F for Hastelloy and Stainless Steel measuring tubes.

Heating Times

The following graphs are provided as a guide only. Heating times were calculated and tested using the following conditions:

• Ambient temperature 25°C or 80°F

• Meter insulated.

The Titanium meters were heated using a steam temperature of 150°C or 300°F and the Hastelloy and Stainless Steel meters using a temperature of 100°C or 210°F.

Heating times may vary depending on the quality of insulation (if any), ambient temperature and temperature of the heating medium. Once meter has been heated to a temperature where the product will not solidify, product may be introduced if required. This will bring the meter to operating temperature sooner.

Note:

The maximum heating temperature for a Titanium meter is 150°C or 300°F. The maximum heating temperature for Hastelloy or SS meters is 100°C or 210°F.

If these temperatures are exceeded, the meter will be damaged.

KROHNE accepts no responsibility if this happens.

Installation and Operating Instructions OPTIMASS

1.2.8 Purge Port Meters and Burst Disk Meters Purge Port Options

If the purge port option was selected at time of order, then your meter will be fitted with ½” NPT female connections – these will be clearly identified. These connections are sealed with NPT plugs and PTFE tape.

Important:

Do not remove these plugs.

The meter is factory sealed with a dry nitrogen gas fill and any ingress of moisture will damage the meter. The plugs should only be removed to purge the inside of the meter case of any product if it is suspected that the primary measuring tube has failed. This must only be done after the meter has been depressurised and removed from service. This should be done as soon as possible after failure is suspected (less than 3 days)

Burst Disk meters (Meters up to size 25 only)

OPTIMASS 7000 meters that have been ordered with a bursting (rupture) disk will be so fitted. This is fitted when the operating pressure of the measuring tube exceeds the design pressure of the secondary containment. The disk failure pressure is 20bar @ 20°C.

Important:

The burst disk is suitable for the designed application according to the process conditions and flow rates as per original order. If conditions alter, consult KROHNE for further advice regarding suitability of disk fitted.

If the product is in any way hazardous, it is strongly recommended that an exhaust tube is connected to the NPT male thread of the burst disk so that the discharge can be piped to a safe area. This tube should

be large enough that pressure cannot build up in the meter case.

Ensure arrow on burst disk is pointing away from meter.

Installation and Operating Instructions OPTIMASS

Flanged and Tri-clamp Meters

When installing these meters ensure that the pipework is supported behind the process flange, so that no unnecessary stress is applied to the meter flanges.

1.First fix meter to firm support

2.Carefully align process flanges and connect

3.Support process pipe close to flanges – do not pull pipe with clamps

4. Make final process connections – if no connections in this area, try to have some flexibility in process pipe

Note :

Please note that gas bubbles can also accumulate between flange and measuring tube due to the step change, mount vertically to avoid this.

1.3.2 Ambient / Process temperatures

The specified and approved ambient and process temperatures must be observed.

SS316L or HC22 °C °F Process -40 .. +150 -40 .. +300

Ambient

Compact -40 .. +55 -40 .. +130 Remote -40 .. +60 -40 .. +140

Note:

Where meters are mounted in direct sunlight, it is recommended to install a sunshade. This is particularly important in countries with high ambient temperatures.

1.3.3 Pressure Equipment Directive (PED) requirements.

To comply with the requirements of the PED in Europe, the following information is provided to assist the plant engineer in installing the meter.

Measuring tube: S Stainless SS 316 L H Hastelloy C22

The outer cylinder (Secondary Pressure containment) 304 / 304L is dual certified and with “0” rings in pairs of Viton and hydrogenated nitrile. (Optional outer cylinder of 316/316L).

Installation and Operating Instructions OPTIMASS

1.3.4 Secondary Pressure containment

The OPTIMASS 3000 (7100) meters are supplied with secondary pressure containment as standard.

Allowable maximum secondary containment pressures are 30 bar at 20°C or 435 psig at 70°F, and is derated as follows :

20 °C 50°C 100°C 150°C 30 bar 28.5 bar 26.1 bar 24 bar

The de-rating is based on the reduction of material strength with temperature for 316L (W No. 1.4404) material from DIN 17456.

Heating jacket is rated to 10 bar at 150°C or 145 psig at 300°F. If heating jacket fitted, secondary containment is limited to 10 bar at 150°C or 145 psig at 300°F. This is because the jacket is fitted inside of the secondary containment dome.

If meter operating pressure is higher than the secondary containment allowable pressure then a relief or

bursting disk option (fitted in the dome) MUST be ordered. In this case the meter data plate is stamped

with maximum pressure rating (at maximum operating temperature) of the connection or the primary tube (whichever is the lower).

Note:

Burst disc options are not available in combination with a heating jacket.

1.3.5 Pressure de-rating

Stainless Steel tubes: 150 bar at 80°C or 2175 psi at 175°F 50 bar at 150°C or 725 psi at 300°F

1.4.6 Hygienic Applications

The OPTIMASS 8000/9000 series is available with a variety of hygienic process connectors. When using / installing meters with hygienic process connectors, care should be taken to ensure the meter is well supported / clamped, as the meters are heavy and could injure when disconnected from the adjacent pipe work. The recommended method of installation is to mount the meter against a support / wall with the body of the meter supported / clamped. The process pipe work can then be supported off the meter. The meter is too heavy to be supported from the thin walled piping usually associated with the hygienic industry.

Support here

3 Start-Up

3.1 Factory Set Parameters

The mass flow meter leaves the factory ready to be used. All process data has been programmed according to the customer order.

When no process details were supplied at the time of order, the mass flow meter is programmed to a standard default set of values and functions.

The current and pulse outputs treat all flows as positive. The actual flow and quantity is thereby measured independent of the flow direction. The indicator will indicate a ” – ” or ” + ” in front of the flow rate.

These factory-set settings for current and pulse may cause an error under the following conditions: When the pump is stopped and a reverse flow is present, which is larger than the low flow cut-off or when totalising should be indicated for both flow directions.

To avoid these possible problems:

• Set flow mode (Fct. 3.1.3) to either flow > 0 or Flow < 0, so that reverse flows are ignored. or

• Increase Low Flow cut-off (Fct. 3.1.1) so that small reverse flows are ignored. or

• Set the alarm output (Fct. 4.6.1) to DIRECTION so that external equipment can differentiate between

positive and negative flows.

3.2 Initial Start-up

• Please check that the power supply corresponds to the information supplied on the data plate.

• Switch on the power supply.

• On switch-on, the signal converter first carries out a self-test. The following sequence is displayed:

Mass flow will be displayed following a brief settling phase for the primary head.

A minimum warm-up time of 30 minutes is recommended to ensure stable measurement operation.

• For stable and accurate mass flow results the following should be checked:

a) The quality of the mechanical installation. See Sect. 1. b) A good zero point calibration should be done. See Sect. 3.3. Further information regarding zero point calibration can be found in Sect. 5.

* TEST * SW.VER VX.XX * OPTIMASS XX5X * START UP

Installation and Operating Instructions OPTIMASS

3.3 Zero point adjustment

After installation adjust the zero point. To do this, the primary head must be completely filled with the liquid

product without gas or air inclusions. This is best obtained by allowing the liquid product to flow through

the primary head for approx. 2 minutes at a throughput rate of greater than 50% of rated flow. Subsequently ensure that flow comes to a complete stop in the primary head (see Section 1.1) for setting the zero without interruption to product flow, use a bypass set-up as shown in Section 1.1.

Now initiate zero adjustment by way of the following keystroke combination:

Start from measuring mode

ACCEPT. (YES) ↵ 3x↵ ↵

Fct. 1.1.(1) AUTO. CALIB. ACCEPT. (YES) Display

Under certain conditions, it may not be possible to adjust the zero point:

• If the medium is in motion. Shut-off valves not tightly closed.

• If there are gaseous inclusions in the primary head. Flush the primary head and repeat the calibration.

• If resonant oscillations of the piping are interfering with the primary head. If there are active warning(s)

in the status message list. (See section 6)

In such cases, the zero point adjustment procedure is automatically aborted and the following message is displayed:

ZERO.ERROR

Press ↵ and then the converter returns to the start of the function 1.1.1:

Fct. 1.1.1 AUTO. CALIB

Further information on zero point adjustment is given in Section 4.

The OPTIMASS is ready to operate after zero has been adjusted.

All parameters have been factory-set in keeping with the data specified in your order. Detailed information for further setting of the signal converter will be found in section 4 and 5 of the operating instructions.

3.4 Programming the converter with a bar magnet

• The converter can be programmed by means of the magnetic sensors mounted on the faceplate

without removing the front lid.

• To do this, a bar magnet (standard supply) is used to activate the sensors by holding the magnet close

to the glass window of the housing lid.

• These sensors then duplicate the functions of the push buttons.

• This is mandatory in Ex

environments

• Also recommended in

5 Description of Functions

In all the following examples, a short notation is used for the setting of the signal converter. Pushing a key several times is indicated by the number of times without the intermediate display messages. Only the final display output is listed.

5.1 Menu 1 - Initial Start up

Zero Point Adjustment Fct. 1.1

When operating the system for the first time, it is necessary to set the zero point of the instrument.

Once the zero point has been adjusted, the installation should not undergo any further modifications in order to maintain the quality of the measurement. This means that after system changes (such as the piping or changing the calibration factor), it is advisable to re-adjust the zero-point.

To achieve a successful zero calibration the primary head should be completely full of process fluid at normal operating pressures and temperatures. Ideally there should be no air inclusions in the fluid, particularly for horizontal installations, so it is recommended that the primary head be flushed with the process fluid at a high flow rate (>50%), for 2 minutes, prior to starting the adjustment. After flushing, flow in the primary head must be brought back to zero by tightly closing appropriate valves.

The zero off-set can either be measured automatically or entered manually using the display keys. If an automatic adjustment is to be made then the operator should trigger this, with the front cover still in place, using the bar magnet provided to operate the magnetic sensors on the display. This is to ensure that the zero adjustment is carried out with the mechanical installation exactly the same as for normal operation.

Begin from the measuring mode.

Installation and Operating Instructions OPTIMASS

Under certain conditions, it may not be possible to adjust the zero point, for instance when:

• The medium is in motion, because the shut-off valves etc. are not functioning properly.

• There are still gaseous inclusions in the primary head because it was flushed insufficiently.

In such cases the zero point adjustment will not be accepted. If the zero adjustment was started by the binary input, the converter will show the message :

ZERO.ERROR

The converter also reports the ZERO.ERROR in the status list.

Under certain circumstances, when the media consists of unevenly mixed components, it might be difficult to adjust the zero point. In such a case, the zero point adjustment procedure must be carried out under special conditions:

• Media which tend to vaporise or degas should be kept under higher pressure.

• Two-phase media consisting of a separable solid component (slurry): In such a case it might be

advisable to fill the primary head with the carrier medium only.

• Other two-phase media.

If it is not possible to separate the solid or gaseous components, the operator can fill the measuring system with a substitute liquid (e.g. with water).

Instrument State Fct. 1.2.

The instrument may be switched to a 'STANDBY' state. Once in this state, all outputs go to their off state and the mass totaliser is frozen. The main display will have the STANDBY indicator set and will display either the frozen totaliser or just STANDBY.

3.456 kg (Frozen Totalizer) STANDBY

Whilst in this state the measuring tube still vibrates and the measurements can come back on line in an instant.

There is an additional standby state, 'STOP', in this case the drive to the primary head is disabled and vibrations cease. However, when leaving STOP the converter has to return to STARTUP before measurements can resume.

The instrument can be switched to STANDBY or STOP either by the keys on the display or by the control input signal (see section 5.4). STOP can only be set by the keys.

To set STANDBY or STOP: Begin from measuring mode

If STANDBY or STOP was selected the instrument goes immediately into that state.

To return to measurement, go back to Fct. 1.2 and select MEASURE.

Installation and Operating Instructions OPTIMASS

Note:

When changing from STOP into STANDBY the instrument will run through the STARTUP mode.

In addition to these 'standby' modes the SYSTEM CONTROL function provides a fully automated way of switching to similar modes using either the density or temperature of the process fluid as a control (see submenu 4.8).

Density Calibration Fct. 1.3

Calibrating the points can only be done when product is in the meter.

The two samples that the density has been calibrated at can be seen in the menu 1.3.1 for point 1 'DISP PT 1' and 1.3.2 'DISP PT 2' for point 2.

If the product was air, pure water or town water then the product name will be displayed. If the product type was 'other' the density will be shown in the units that the density was entered at calibration time.

Factory Calibration

This enables the user to recall the factory calibration settings.

• Menu 1.3.5 FACTORY.SET

• Enter the menu

• Sure Yes/No

• Yes displays please wait while the calibration is restored.

• CALIB OK or CALIB FAIL is then displayed.

One Point Calibration

Menu 1.3.3 '1 POINT CAL' - This does not allow the user to decide which point to move; the converter decides the most appropriate point to move. The user chooses the product type that is in the meter and moves the best point. The choices are Air, Pure water, Town water and Other. If “Other” is selected, the product density needs to be entered. You can enter the density in any of the normal density units.

If you select ‘pure water’, ‘air’ or ‘town water’ the density does not need to be entered. Once selected PLEASE WAIT is displayed. Density calibration should take about 1 second. After this time the result of the calibration will be displayed.

CALIB OK - the point has been entered correctly. To see which point has been changed go to menu 1.3.1 'DISP PT1' and 1.3.2 'DISP PT2'.

CALIB FAIL - the density calibration failed. There are a number of causes for this:

1. Not in measuring mode

2. The 2 points are too close

3. The 2 points fail a plausibility check

Normally a 1 point calibration is adequate for most density calibrations e.g. tailoring the density to the new installation. The 1 point calibration can be done twice, with two different products to achieve a 2 point calibration. However, there is no guarantee that the first point is entered will not be moved when the second point is entered. In this case, it is better to use the two point calibration method.

Two Point Calibration

This is when the user wants to enter 2 set points. The 2 point calibration makes sure that the 2 points entered by the user are used.

Warning - 2 point calibration will restore the factory calibration data before calibrating the 1st point.

5.2 Menu 2 – Functional Checks

Menu 2.0. contains a number of test functions. These allow the current, frequency and alarm outputs to be driven at a number of fixed test levels, so that the communication between the converter and the customer's equipment can be verified. In addition, other functions allow various measured parameters from the primary head to be viewed directly for trouble shooting purposes.

Testing the display Fct. 2.1

This function sends a test sequence to the LCD display which causes each element of the display to be lit in sequence. If any segments fail to light, this indicates that the display is faulty and should be replaced.

Testing the pulse output Fct. 2.5

To test the pulse output, connect an external counter to the output terminals. When testing the pulse output, the operator has the choice of the following pulse widths: 0.4 ms, 1.0 ms, 10.0 ms, 100.0 ms and 500 ms. The operator should choose the pulse width that best matches the performance of his external pulse counter. Connect a pulse counter to the impulse output and proceed as follows:

The meter now issues a stream of pulses with the set width. The running total of pulses sent is shown on the display. The test stops when either 100,000 pulses have been sent or the operator presses the ↵ key. A connected counter will now count. Press ↵ to stop the counting. The meter display and counter should have matching totals.

If the counter reads a smaller number than the actual number of pulses sent, or the frequency meter under reads, then this indicates that a weak signal is reaching the frequency meter/pulse counter. In this case try the following suggestions:

• Decrease the external pull-up resistor

• Decrease/remove the filter capacitor.

• Decrease the cable length between the converter and the counter.

• Add external buffers to boost the signal.

If the pulse counter reads a larger number than the converter, or if the frequency meter reading is high or unstable, then this indicates the presence of external interference. Try one or more of the following:

• Add/increase the size of the filter capacitor. (10...100nF)

• Use high quality screened cable.

• Keep cable lengths as short as possible, avoiding high power equipment/switchgear and any cabling

connected to them.

• Use external buffers.

Testing the Frequency Output Fct. 2.6

This function allows the frequency output to be tested. The Frequency output has an open collector transistor drive which requires a pull-up resistor to an external DC power supply. To test the frequency, connect a frequency counter to the output terminals and proceed as follows:

Low Flow Cut Off Fct. 3.1.1

If the flow mode in (Fct. 3.1.3. is set to Flow +/- then at zero flow small signal fluctuations will average out to nothing and the totaliser will remain static. However, if ‘unidirectional’ flow is selected, this process will not work and the totaliser reading will increment slowly with time. To prevent this, the Low Flow cut off should be set. The Low Flow cut off is entered as a percentage of the rated nominal flow of the primary head. The cut off may be set from 0 to 10% in increments of 0.1%. Thus for example a 7000 T25 (nominal flow 34500 kg/h or 1250 lbs/min) with a low flow cut off of 0.2%, any flow less than 69kg/hr or 2.5 lb/min will indicate zero on the display.

Measurements taken from the sensor are digitally filtered to provide stable readings in the event of fluctuating flows. The degree of filtering also affects the response time of the reading due to rapid changes in the flow.

Short time constant:

• Fast response

• Fluctuating reading

The figure below shows the typical response of the measurement for varying time constants and a rapid change in flow.

Pressure Suppression Fct. 3.1.8 and 3.1.9

The Pressure Suppression feature eliminates any influences on the measurement result of sudden termination of flow, such as when a valve is shut. When this occurs the propagation of pressure waves along the pipe work and through the meter may produce an “Over-shoot” or “ringing” effect, where the flow rate will oscillate backwards and forwards until it settles to a stable zero flow condition, as is indicated in the diagram below. Typically this will only be noticeable on high pressure applications.

In most cases the amplitude of the ringing will be below the “Low Flow Threshold” and will therefore not influence the result. In some cases however the amplitude of the ringing is above the Low Flow Threshold and could contribute an error in the totaliser values.

The pressure suppression function eliminates this effect, by increasing the Low Flow Cutoff for a short period of time, triggered when the flow first drops below the Low Flow Threshold. For a set time period (set in Fct. 3.1.8) the pressure suppression threshold (set in Fct 3.1.9) is added to the standard Low Flow Threshold (set in Fct. 3.1.1).

Settings of these parameters depend on actual process conditions and characteristics of the pipework and so can only be determined by experimentation in-situ.

Zero Problems

• Perform auto zero, observe the displayed value, it should be stable and lower than +/- 0.5%

• If the result is bad:

Stop flow, set 3.1.1 Low flow cut off to 0, 3.1.3 Flow Mode to “+/-”, perform auto zero, and totalise over 2 minutes. Compare totalised flow to specified zero stability.

For best process results, zero setting should be performed on process fluid at process temperature.

High Zero’s can be caused by: Leaking valves, Air/Gas inclusions, Coating on tube.

6.4 Replacing the Front End or Back End Electronics

If a failure occurs in one or the other of the above electronics, these can be easily replaced with the minimum downtime. Please remember to disconnect or switch off the power supply to the meter when performing these tasks. Please observe the waiting time for Hazardous area approved meters.

To make exchanging the components easy, a copy of the Front End calibration coefficients are stored in the Back End as well. This facilitates the changes without the necessity of sensor calibration coefficients.

Note:

The following functions must only be performed by qualified personnel.

6.4.1 Replacing the Front End

• Please unscrew the four small screws holding the Front End in place (screws at the rear).

• Take care when removing to ensure that the connections are not damaged.

• Do not lose the gasket.

• Replace with new Front End electronics, ensuring that the gasket is well positioned and the

connections have mated correctly.

• Do not force the connectors.

• Tighten securely.

• It is recommended that some locktite or similar compound is used for the screws.

After power up the measuring system will recognize a hardware change. The display will show Sys. Changed.

6.4.2 Replacing the Back End

Unscrew the front lid and undo the two screws holding the display in place. The two screws holding the converter in the housing can now be seen towards the rear on the steel frame. Take care not to damage any components while attempting to loosen these screws.

The converter will slide out easily after disengaging from the rear terminals in the case of EX/FM converters. If the converter is a general purpose / non EX converter then the plugable terminals in the rear terminal compartment need to be unplugged before the converter can be removed.

To retain the user-configured data, the small EEPROM can be removed and installed on the replacement converter. This will save re-programming the user range and output configuration data.

Position of small EEPROM.

The replacement converter can now be installed and fixed in place. Replace the display and close the converter housing. Switch power back on. The display will show Sys. Changed.

Note:

After Sure Yes has been accepted, the word Uploading will be displayed. Once complete, the meter will display start-up and continue. If the message Failed is displayed, then the configuration stored was not valid and the previous menu will be displayed after pressing the return key. Consult the factory.
