Electromagnetic flowmeter#39; measurement principle is Faraday#39;s law of electromagnetic induction. The main components of the sensor are: measuring tube, electrode, excitation coil, iron core and yoke housing.It is mainly used to measure the volumetric flow in conductive liquids and slurries in closed pipes.

Electromagnetic Flow Meters, simply known as mag flow meter is a volumetric flow meter which is ideally used for waste water applications and other applications that experience low pressure drop and with appropriate liquid conductivity required.

The device doesnrsquo;t have any moving parts and cannot work with hydrocarbons and distilled water. Mag flow meters are also easy to maintain.

Principle of Magnetic Flow Meter Based on Faradayrsquo;s Law

Magnetic flowmeters works based on Faradayrsquo;s Law of Electromagnetic Induction. According to this principle, when a conductive medium passes through a magnetic field B, a voltage E is generated which is proportional to the velocity v of the medium, the density of the magnetic field and the length of the conductor.
