System description
VARIFLUX electromagnetic flowmeters are precision measuring instruments designed for the
linear flow measurement of process liquids.
The process liquids must be electrically conductive:
≥
0 5
µ
S/cm
≥
20
µ
S/cm for demineralized cold water
The full-scale range Q
100%
can be set as a function of the meter size:
DN 2.5 - 80 / 1 /
10
” - 3” Q
100%
= 0.01 - 220 m 3 /hr = 0.03 - 960 US Gal/min
This is equivalent to a flow velocity of 0.3 - 12 m/s, or 1 - 40 ft/s.
Product liability and warranty
VARIFLUX electromagnetic flowmeters are designed solely for measuring the volumetric flowrate
of electrically conductive, liquid process products.
Special codes and regulations apply to their use in hazardous locations, and these are referred to
in the special “Ex” installation and operating instructions (supplied only with hazardous-duty
equipment).
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 VARIFLUX flowmeters need to be returned to Krohne, please note the information given on the
last-but-one page of this manual. Krohne regret that they cannot repair or check your flowmeter(s)
unless accompanied by the completed form sheet.
