System description Electromagnetic flowmeters with the IFC 020 signal converter 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 Q100% can be set as a function of the meter size: Q100% = 0.0060 - 86 860 m3/hr = 0.03 - 156.672 US Gal/min This is equivalent to a flow velocity of 0.3 - 12 m/s or 1 - 40 ft/s.

HART operating tools / Device Description (DD) The IFC 020 can be operated either via its local operator interface or by means of the HART communicator or the CONFIG program. Both operating tools are available from KROHNE. Operator control by means of the HART communicator requires a device description (DD) which we can load for you into the communicator. We can, of course, also load the DDs of all manufacturers who have filed their DDs with the HART Communication Foundation.

11 Measuring principle The flowmeter is designed for electrically conductive fluids. Measurement is based on Faraday’s law of induction, according to which a voltage is induced in an electrically conductive body which passes through a magnetic field. The following expression is applicable to the voltage.
