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.
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.
The induced voltage is carried to the transmitter through the electrode circuit.
The physical principle at work is electromagnetic induction.
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 flowmeters can measure properly when the electrical conductivity of the liquid is greater than approximately 5μs cm.
The induced voltage e is directly proportional to the velocity v of the fluid moving through the magnetic field b.
