Magnetic Flow Meter Working Principle

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.

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. What is the working principle of magnetic flow meter. The flow principle behind magnetic flow meters is known as faraday s law mathematically defined as e k b d v. 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.

The induced voltage is carried to the transmitter through the electrode circuit. 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. Magnetic flow meters works based on faraday s law of electromagnetic induction. Principle of magnetic flow meter based on faraday s law.
