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.

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.

6 Mu-metal foil, 2nd shield
7 Stranded drain wire, 2nd shield, 0.5 mm² or AWG 20
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.
