Magnetic Flow Meter Working Principle

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

Magnetic flow meter working principle.

The induced voltage e is directly proportional to the velocity v of the fluid moving through the magnetic field b. The physical principle at work is electromagnetic induction and mathematically defined as e k b d v. The induced voltage is carried to the transmitter through the electrode circuit. The physical principle at work is electromagnetic induction.

Principle of magnetic flow meter based on faraday s law. 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. 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 flow principle behind magnetic flow meters is known as faraday s law mathematically defined as e k b d v.

Magnetic flowmeters can measure properly when the electrical conductivity of the liquid is greater than approximately 5μs cm. 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. What is the working principle of magnetic flow meter.
