Magnetic Flow Meter Working Principle

Principle of magnetic flow meter based on faraday s law.

Magnetic flow meter working principle.

The flow principle behind magnetic flow meters is known as faraday s law mathematically defined as e k b d v. The induced voltage is carried to the transmitter through the electrode circuit. 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 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. These meters are also called as magflow or electromagnetic flow meters. 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. Be careful because using magnetic flowmeters on fluids with low conductivity such as deionized water boiler feed water or hydrocarbons can cause the flowmeter to turn off and measure zero flow.

The physical principle at work is electromagnetic induction. Magnetic flowmeters can measure properly when the electrical conductivity of the liquid is greater than approximately 5μs cm. Magnetic flow meters works based on faraday s law of electromagnetic induction.
