Magnetic Flow Meter Working Principle

The induced voltage is carried to the transmitter through the electrode circuit.

Magnetic flow meter working principle.

A magnetic field is applied to the metering tube which results in a potential difference proportional to the flow velocity perpendicular to the flux lines. A magnetic flow meter mag meter electromagnetic flow meter is a transducer that measures fluid flow by the voltage induced across the liquid by its flow through a magnetic field a magnetic field is applied to the metering tube which results in a potential difference proportional to the flow velocity perpendicular to the flux lines. Principle of magnetic flow meter based on faraday s law. Faraday s law the operation of a electromagnetic flowmeter is based upon faraday s law which states that the voltage induced across any conductor as it moves at right angles through a magnetic field is proportional to the velocity of that conductor.

Magnetic flow meters works based on faraday 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. Electromagnetic flow meter is a volumetric flow meter which measures the flow of liquid by the induced voltage across liquid by its flow through a magnetic field using faraday s law of induction where no moving part makes it ideal for wastewater applications or any dirty liquid which is conductive or water based. The induced voltage e is directly proportional to the velocity v of the fluid moving through the magnetic field b.
