Electromagnetic Flowmeter


Line size selector chart

  • Flow Star series FEMAG are micro-controller based full bore type electromagnetic flow transmitter specially used for various industrial applications
  • These flow transmitters accurately measures the flow rate of conductive liquids & slurries in closed pipes
  • Due to simple & rigid design the flow transmitter is an obstruction less & maintenance free instrument in place of conventional mechanical flow measuring device
  • The use of ‘Pulsed DC’ technology offers highest ability & better measuring accuracy in the form of electrical signal 4 – 20 ma DC linearly proportional to volumetric flow
  • The instrument is based on Faraday’s law of electro-magnetic induction. A magnetic field is generated by the instrument in the flow tube
  • The fluid flowing through this magnetic field generates a voltage that is proportional to the flow velocity. Corresponding electrical output is provided with respect to measuring voltage

Salient Features:

  • Indication through LED / LCD
  • Full Bore type
  • Microprocessor based
  • Simple & cost effective construction
  • Provides wide flow ranges
  • Outstanding accuracy
  • Operates over wide ranges of temperature & pressure
  • Easy maintenance as no moving parts
  • Pulsed DC coil excitation
  • Flame-proof, IP-65, IIA, IIB CMRI certified housing
