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.
What is the working principle of magnetic flow meter.
Principle of magnetic flow meter based on faraday s law.
The physical principle at work is electromagnetic induction and mathematically defined as e k b d v.
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.
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.
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.
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.
The induced voltage is carried to the transmitter through the electrode circuit.
