2. Magnetic flow meter - Wikipedia

   en.wikipedia.org/wiki/Magnetic_flow_meter

   A magnetic flow meter (mag meter, electromagnetic flow meter) is a transducer that measures fluid flow by the voltage induced across the liquid by its flow through a magnetic field. A magnetic field is applied to the metering tube, which results in a potential difference proportional to the flow velocity perpendicular to the flux lines.

3. Water metering - Wikipedia

   en.wikipedia.org/wiki/Water_metering

   Electromagnetic flow meter Magnetic flow meters , commonly referred to as "mag meters", are technically a velocity-type water meter, except that they use electromagnetic properties to determine the water flow velocity, rather than the mechanical means used by jet and turbine meters.

5. Electromagnetic induction - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_induction

   Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction .

6. Lorentz force velocimetry - Wikipedia

   en.wikipedia.org/wiki/Lorentz_force_velocimetry

   Lorentz force velocimetry [1] (LFV) is a noncontact electromagnetic flow measurement technique. LFV is particularly suited for the measurement of velocities in liquid metals like steel or aluminium and is currently under development for metallurgical applications. The measurement of flow velocities in hot and aggressive liquids such as liquid ...
