System description

Electromagnetic flowmeters are precision instruments designed for linear flow measurement of liquid products

The process liquids must be electrically conductive:, 5 µS/cm (for cold demineralized water 20 µS/cm).

The full-scale range Q100% can be set as a function of the meter size: flow velocity of 0.3 - 12 m/s or 1 - 40 ft/s (s. Section 10.4.).

Product liability and warranty

The electromagnetic flowmeters are designed solely for measuring the volumetric flowrate of electrically conductive, liquid process products.

These flowmeters are available for use in hazardous areas.

Special regulations apply in this case, which are given in the special EEx directions.

Responsibility as to suitability and intended use of these electromagnetic flowmeters rests solelywith the operator.

Improper installation and operation of the flowmeters (systems) may lead to loss of warranty.

In addition, the “General conditions of sale” forming the basis of the purchase contract are applicable.

If flowmeters need to be returned to KROHNE, please note the information given on the last-but- one page of these Instructions. KROHNE regrets that it cannot repair or check your flowmeter(s) unless accompanied by the completed form sheet.

CE / EMC / Standards / Approvals

Sect. 1.1

Part A System installation and start-up

1 Electrical connection: power supply

1.1Location and important installation notes ……………………. PLEASE NOTE !

Electrical connection in accordance with VDE 0100 ”Regulations for the erection of power installations with nominal voltages up to 1000 V” or equivalent national regulations.

Do not cross or loop cables inside the terminal compartment.

Use separate wiring (PG screwed cable entries) for power supply, field current lines, signal lines, outputs and inputs.

Hazardous areas are subject to special regulations, see Section 6.1 and special installation instructions for hazardous-duty versions.

Do not expose signal converter and switchgear cabinets with built-in converters to direct sunlight. Install a sunshade if necessary.

Signal converters installed in switchgear cabinets require adequate cooling (e.g. by fans or heat exchangers).

Do not expose signal converters to intense vibration.

Keep the distance between the flow sensor and signal converter as small as possible, for empty pipe detection (EPD) 20 m / 66 ft. Observe maximum lengths of signal and field current lines (see Section 1.3.4).

Use KROHNE signal line A (type DS, standard) or signal line B (type BTS, bootstrap, optional), standard length 10 m (33 ft).

Generally use bootstrap signal lines B (type BTS) for PROFIFLUX 5000 F and VARIFLUX 6000 F flow sensors sized at DN 2.5-15 and 1/10’’-1/2’’ and for contaminated liquids which tend to form electrically insulating deposits.

Always calibrate flow sensor and signal converter together. During installation particular care should therefore be given to identical settings of flow sensor constant GK (see instrument nameplate of flow sensor). In case GK constants are not identical, the signal converter must be adjusted to the flow sensor GK (see Sections 4 and 8.5).

Dimensions of signal converter see Section 10.3.

IMPORTANT!

For EEx versions, also pay regard to all directions included in Sect. 6.1 and 13.

Only the EEx flow sensor may be installed in the hazardous area. The EEx certified signal converter must be installed outside the hazardous area!

Sect. 1.2

1.2Power supply - connection

PLEASE NOTE !

Type of enclosure IP 65 to IEC 529 / EN 60529 equivalent to NEMA 4/4X.

Dimensioning: the flowmeter housing protecting the electronic equipment against dust and moisture must always be kept closed. The selected clearances and creeping distances comply with VDE 0110 and/or IEC 664 regulations for contamination grade 2. Supply circuits and output circuits are designed to meet standards of overvoltage classes III and II, respectively.

Fuse protection, disconnecting device: fuse protection for the feeding power circuit, and also a disconnecting device (switch, circuit breaker) for isolating the signal converters must be provided (see also Sect. 1.3.5 and 1.3.6).

100-230 V AC (tolerance range 85-255 V AC)

Observe information on the instrument nameplate, power supply voltage and frequency.

The protective conductor PE of the power supply must be connected to the separate U-clamp terminal inside the terminal compartment of the signal converter.

CAUTION: do not remove the internal connection (line) inside the terminal compartment of the signal converter (yellow/green wire) between the U-clamp terminal and terminal 10 - protective conductor (protection class I instrument).

Connection diagrams I - IV for the power supply and for the electrical connection between flow sensor and signal converter, see Sections 1.3.5 (Standard) and 1.3.6 (EEx).

24 V AC / DC (tolerance ranges: AC 20.4 - 26.4 V / DC 18 - 31.2 V)

Observe information on the instrument nameplate, power supply voltage and frequency.

For technical reasons concerning the measuring process, a functional grounding conductor FE has to be connected to the separate U-clamp terminal inside the terminal compartment of the signal converter.

A facility providing a reliable electrical separation (PELV) has to be provided for connections to functional extra-low voltages (24 V AC / DC) - (VDE 0100 / VDE 0106 and/or IEC 364 /

IEC 536 or equivalent national regulations).

Connection diagrams I - IV for the power supply and for the electrical connection between flow sensor and signal converter, see Sections 1.3.5 (Standard) and 1.3.6 (EEx).

IMPORTANT!

For EEx versions, also pay regard to all directions included in Sect. 6.1 and 13.

Only the EEx flow sensor may be installed in the hazardous area. The EEx certified signal converter must be installed outside the hazardous area!

Warning: Instrument must be properly grounded to avoid personnel shock hazard.

1.3Electrical connection of flow sensors

1.3.1 General remarks on signal lines A and B and field current line C

Proper operation of the equipment is ensured when KROHNE signal lines A and B are used with foil screen and magnetic shield.

Signal lines must be firmly installed.

Shields are connected via stranded drain wires.

Underwater or underground routing is possible.

Insulating material flame-retardant to IEC 332.1 / VDE 0742.

Low-halogen, unplasticized signal lines which remain flexible at low temperatures.

Signal line A (type DS) with double shielding

1Stranded drain wire, 1st shield, 1.5 mm² or AWG 14

2Insulation

3Stranded wire 0.5 mm² or AWG 20 (3.1 red/3.2 white)

4Special foil, 1st shield

5Insulation

6Mu-metal foil, 2nd shield

7Stranded drain wire, 2nd shield, 0.5 mm² or AWG 20

8Outer sheath

Signal line B (type BTS) with triple shielding (bootstrap line)

The bootstrap technology always controls the individual shields (3) of the signal converter exactly to the voltage which is supplied to the signal conductors (5). As this prevents voltage differences between the individual shields (3) and signal conductors (5), no current flows via the line capacitances between 3 and 5. The line capacitance seems to become ”zero”.

This allows greater cable lengths in case the electric conductivity of the liquid to be measured is low.

1.3.3 Grounding of flow sensor

The flow sensor must be correctly connected to ground.

The grounding cable may not transfer interference voltages.

Do not use the grounding cable to connect more than one device to ground.

In hazardous areas the grounding line is also used for potential equalizing purposes. Special grounding instructions are contained in the installation instructions for hazardous-duty instruments (only supplied together with such instruments).

The flow sensor is connected to ground by means of a functional grounding conductor FE.

Special grounding instructions for the connection of several flow sensors are contained in the separate installation instructions of the flow sensors.

These instructions also contain detailed descriptions on how to use grounding rings and how to install flow sensors in metal or plastic pipes or in pipes which are coated on the inside.

Warning: Instrument must be properly grounded to avoid personnel shock hazard.

IMPORTANT!

For EEx versions, also pay regard to all directions included in Sect. 6.1 and 13.

Only the EEx flow sensor may be installed in the hazardous area. The EEx certified signal converter must be installed outside the hazardous area!

1.3.6 EEx-Connection diagrams for power supply and flow sensors PLEASE NOTE!

The figures in brackets indicate the stranded drain wires for the shields (see cross-sectional drawing of signal cable in Section 1.3.1).

The connections for the intrinsically safe electrode circuit including the shield terminals are safety-separated up to a peak value of 375 V from the terminals for thepower supply, for the inputs/outputs and for the field circuit. They are galvanically isolated from the housing (PE/PA).

For connection of the intrinsically safe electrode circuit including shield terminals to the primary head, please refer to Item 12 in EN 60079-14.

The non-intrinsically safe field circuit to be connected to the primary head in keeping with the requirements of Item 9 in EN 60079-14 .

The non-intrinsically safe input and output circuits may only be routed into the hazardous area in compliance with appropriate measures as specified in EN 60079-14.

Supply power (terminals 11,12)

In conformity with current regulations for electrical installations, an isolating facility is required to be provided for the signal converter. The housing of the IFC 110 F – EEx signal converter must be incorporated in the equipotential bonding system (via external PA connection).

Note! A PE safety conductor is not connected if a functional extra-low voltage with safety separation (PELV) is used. Grounding is then carried out by way of the equipotential bonding conductor.

Electrode circuit (terminals 1, 20, 2, 3, 30 and shield terminal S)

In conformity with the requirements for separation of intrinsically safe circuits, Category ib to EN 50 020, the cable for the intrinsically safe electrode circuit must, up to the terminals, be separated from all non-intrinsically safe circuits.

Terminals 20 and 30 are optionally provided for connecting cables with single shielding. The terminal for the outer shield (S) is capacitance grounded in the signal converter. The outer overall shield to be connected by the shortest possible wire to the shield terminal. Shields to be carefully insulated from ground and from each other.

Field circuit FSV (terminals 7, 8)

The field circuit is all-pole protected on the FSV circuit board with an internal fusible link

160mA / 250V.

Input/output circuits

The connection is made to functional extra-low voltage circuits with safety separation (PELV). The I/O functions and technical data are described in the Standard Installation and Operating Instructions.

IMPORTANT!

For EEx versions, also pay regard to all directions included in Sect. 6.1 and 13.

Only the EEx flow sensor may be installed in the hazardous area. The EEx certified signal converter must be installed outside the hazardous area!

*Do not remove the internal connection (cable) inside the terminal compartment of the signal converter (yellow/green wire) between the U-clamp terminal and terminal 10 (protective conductor for protection class I instruments).

2.7Standard factory settings

All operating data are set at the factory in accordance with the specifications contained in the order.

If no specifications are made in the order, instruments will be delivered with the standard parameters and functions indicated in the table below.

To facilitate the start-up of the instrument, current and pulse outputs are set to handle measurements in ”two flow directions” so that the current flow rates and volumes are displayed and/or counted independent of the direction of flow. The figures displayed may have a preceding sign.

Such factory setting of current and pulse outputs may lead to measuring errors, particularly when volumes are metered and totalized.

If e.g. pumps are switched off and ”backflows” occur which are not within the low-flow cutoff (SMU) range, or if separate displays and counts are required for both flow directions.

To avoid faulty measurements, it may therefore be necessary to change the setting of the

following functions:

 

- SMU low-flow cutoff

- display

- current output I
