Electromagnetic Flowmeter Principle and Feature

Electromagnetic Flowmeter Measurement Principle

The electromagnetic flowmeter uses Faraday's Law of electromagnetic induction to measure the process flow.

When an electrically conductive fluid flows in the pipe, an electrode voltage E is induced between a pair of electrodes placed at right angles to the direction of magnetic field.
The electrode voltage E is directly proportional to the average fluid velocity V.

Divided multi-sampling system using advanced algorithms

Toshiba's original Noise-suppression circuit shuts off the noise induced by slurry or commercial frequency.
It always keeps stable flow measurement with high accuracy.
