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 Q
can be set as a function of the meter size: flow velocity of 0.3 - 12 m/s
100%
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.

1 Electrical connection: power supply
1.1 Location 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!

1.3 Electrical 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 B (type BTS) with triple shielding (bootstrap line)
8 Outer sheath
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 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

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

2.7 Standard 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 Fct. 1.03, Section 5.3
- display Fct. 1.04, Section 5.5
- current output I Fct. 1.05, Section 5.6
- pulse output P Fct. 1.06, Section 5.7
• For special applications, such as pulsating flows, see Sections 6.5 to 6.10
