Electromagnetic Flow Meter

EFS808 (Battery-powered)

electromagnetic flow meter efs808

Electromagnetic Flow Meter EFS808 offers accurate, reliable and stable flow measurement of liquids for a wide range of applications.

The EFS 808 complies with OIML R49, and features analog or digital output, digital communication, data logger with MicroSD Memory. It is available as compact or remote version, and is battery-powered, making it a better option for flow measurement in remote area. 

  • Reliable flow measurement for conductive fluid > 5μS/cm.
  • Process medium temperature, viscosity, density has no influence on the flow measurement.
  • Flow sensor is maintenance free, no moving part and straight through flow tube (no pressure loss).
  • With wide selection of lining and electrodes material, flow measurement of very corrosive liquid (e.g. acids, caustic and corrosive chemicals) is not an issue.
  • Data logger (MicroSD Memory 4GB) is optional.

  • EFS808 Battery powered version available.
  • Electromagnetic flow meter EFS808 can be used for precise flow measurement of all electrically conductive liquids sludges, slurries, sewage, milk, water waste water.
  • iSOLV electromagnetic flow meter has many applications across many industries
  • Water waste water Treatment
  • Building Automation (HVAC)
  • Food & Beverage
  • Chemical
  • Pulp and paper
