Electromagnetic flow meter

Electromagnetic flow meters measure the flow of conductive liquids without restricting the line and without moving parts. They are widely used for water, wastewater, chemicals and other conductive liquids in industry.

Operation

  • Based on Faraday's law of induction: a conductor (here, the liquid) moving through a magnetic field generates a voltage.
  • This voltage is proportional to the pipe diameter and the flow velocity of the liquid.
  • Electrodes pick up this voltage, which is converted into flow velocity.

Advantages

  • No moving parts: no flow restriction, low risk of wear.
  • High accuracy: measuring errors as low as ±0.2%.
  • Wide range of liquids: although limited to conductive liquids, it offers broad chemical compatibility.
  • Low maintenance: no mechanical internals, long service intervals.

Applications

  • Potable water and wastewater metering
  • Control of acids and alkalis
  • Dosing of liquids such as milk and fruit juice
  • Cooling water systems

Considerations

  • The minimum conductivity of the liquid matters; it should usually be >5 μS/cm.
  • The measuring tube must always be completely full; measurements in a partially filled line are inaccurate.
  • Make sure the electrodes are in proper contact with the liquid.
