MFE600E Electromagnetic Flowmeter for Water Treatment and Irrigation

The measurement principle of MFE600E electromagnetic flowmeters is based on Faraday’s law of induction. MFE600E can accurately measure the flow of any electrically conductive liquid, even
those with low conductivities (starting from 5 μS/cm).


  • Water industry: revenue metering, district metering, water abstraction
  • Irrigation: Pumping station, pipe line, leakage detection
  • Pulp & paper industry: pulp, pastes, sludges and other caustic mediums, liquor, additives, bleaches, colourants
  • Metal & mining industry: mediums with a high solid content, like ore or excavator mud

  • Open flow, no moving components, and no pressure loss in the measurement pipe
  • Multiple material choices of electrode and lining, solid against highly corrosive or abrasive medium and applications
  • Multiple parameters displayed, including flux, transient flux, velocity, flow %, etc
  • Forward flux and reverse flux can be measured
  • The variations in fluid density, viscosity, temperature, pressure, and electrical conductivity will not affect accuracy
  • EEPROM store parameter settings and cumulative values when power off, supports zero drift, self-diagnosis and alarm functions
  • With integrated grounding electrode (DN25-DN500), no need of grounding ring
  • Remote display available. Flange, sanitary, threaded, clamping type installation optional.

Working Principle

Based on Faraday’s Law of Electromagnetic Induction, the Electromagnetic Flowmeter’s operation produces an induced electromotive force in the liquid conductor as the conductive liquid flows through it.

This electromotive force is directly proportional to the liquid’s velocity, the magnetic flux density, and the conductor’s width (interior diameter of the flowmeter). A pair of electrodes on the flowmeter’s tube wall detect this generated electromotive force, which has the following equation for its magnitude:

U = K×B×V×D

U: Induced electromotive force

K: Instrument Constant

B: Magnetic flux density

V: Velocity

D: Interior diameter of measuring pipe
