Electromagnetic Flowmeter - EFS800 Overview

The measuring principle of the electromagnetic flowmeter (Magmeter) is based upon the Faraday's Law of electromagnetic induction; whereby a voltage is induced by an electrical conductor passing through a magnetic field.

In electromagnetic flowmeter, the medium acts as the electrical conductor when flowing through the meter tube, the induced voltage is proportional to the average flow velocity (the faster the flow rate, the higher the voltage).

The induced voltage is picked up by a pair of electrodes (mounted in the meter tube) and transmitted to a flow transmitter to produce various standardized output signals.Using the pipe cross-sectional area, the volumetric flow rate is calculated by the transmitter.

The following equation is applicable to the induced voltage: U = kBVD where

Electromagnetic Flowmeter - EFS800 Features

  • Reliable flow measurement for conductive fluid > 5mS/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.
