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
100%
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 10.1.).

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 solely
with 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.

IMPORTANT!
In respect of EEx versions, pay regard to all directions marked with the symbol,
and also the information given in Sect. 6.1 and 13.
Only the EEx primary head may be installed in the hazardous area.
The signal converter must be installed outside the hazardous area!
