System description Electromagnetic flowmeters with the IFC 010 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: 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.

Measuring principle and function of the system 11 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.
