• The measuring principle is virtually independent of pressure, density, temperature and viscosity
• Even fluids with entrained solids can be metered, e.g. ore slurry or cellulose pulp
• Wide range of nominal diameters (DN 2 to 3000; 1/12 to 120″)
• Free pipe cross-section: CIP/SIP cleanable, piggable
• No moving parts, maintenance-free

Faraday’s law of induction states that a metal rod moving in a magnetic field induces electrical voltage. This dynamo principle also governs the way electromagnetic flowmeters work. As soon as the electrically charged particles of a fluid cross the artificial magnetic field generated by two field coils, an electric voltage is induced. This voltage, tapped by two measuring electrodes, is directly proportional to the velocity of flow and thus to the flow volume. The magnetic field is generated by a pulsed direct current with alternating polarity. This ensures a stable zero point and makes the flow measurement insensitive to multiphase or inhomogeneous liquids, as well as low conductivity.
