Magnetic flow meter working principle.

The physical principle at work is electromagnetic induction. The flow principle behind magnetic flow meters is known as faraday s law mathematically defined as e k b d v. What is the working principle of magnetic flow meter. Principle of magnetic flow meter based on faraday s law.

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. 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. These meters are also called as magflow or electromagnetic flow meters.

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