System description
Electromagnetic flowmeters with the IFC 090 signal converter are precision instruments designed
for linear flow measurement of liquid products.
The process liquids must be electrically conductive: ≥5µS/cm
(for cold demineralized water ≥20 µS/cm).
The full-scale range Q100% can be set as a function of the meter size:
DN 2.5.- 1000 / 01/10” - 40” Q100% = 0.010- 34 000 m3/hr = 0.03 - 151 000 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
The electromagnetic flowmeters with the IFC 090 signal converter are designed solely for
measuring the volumetric flowrate of electrically conductive, liquid process products.
Special codes and regulations apply to their use in hazardous areas 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 compact 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.
• Electro magnetic flowmeters with the IFC 090 signal converter meet the requirements of the
EU-EMC Directives and bear the CE symbol.
• All factories and production sequences are ISO 9001 certified.
• Flowmeters are approved as hazardous-duty equipment to the harmonized European
Standards and to Factory Mutual (FM).
Further details are given in the “Ex” supplementary instructions provided only with
hazardous-duty equipment.
Items included with supply
• Signal converter as ordered
• Installation and operating instructions
• 2 plug connectors for power supply and outputs/inputs
• Special wrench for opening the housing covers
• Bar magnet to operate the display converter without opening the housing
• Additional instructions for hazardous-duty versions (applies only to hazardous-duty equipment)
