The electromagnetic flowmeter Riels-LFE using Faraday's law of electromagnetic induction to measure the flow of electrically conducting liquids, according to which a conductor crossing a magnetic field generates a potential oriented perpendicularly to the field itself.

Advantages
  • Compact and lightweight
  • Reverse flow can be detected
  • With integrated display in 3 colors
  • Bidirectional measures
  • Repeatability ± 1.5% F.S.
  • Without pressure drop
