Magnetic Flow Meter Working Principle Animation

The two blue dots in the animation indicates electrodes.

Magnetic flow meter working principle animation.

The device doesn t have any moving parts and cannot work with hydrocarbons and distilled water. Principle of magnetic flow meter based on faraday s law. Mag flow meters are also easy to maintain. Magnetic flow meters works based on faraday s law of electromagnetic induction.

The copper coils red blocks magnets on top bottom of the instrument are electro magnets used to generate a magnetic field. According to faraday s law of electromagnetic induction whenever a conductor is placed in a magnetic field an emf is induced which is called induced emf. Principle of operation simply magnetic flow meters works on faraday s law of electro magnetic 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.

As per michael faraday electric current can be generated by a magnetic field.
