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.

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!

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.

•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!
