Magnetic Blood Flow Meter Principle

Magnetic flow meters works based on faraday s law of electromagnetic induction.

Magnetic blood flow meter principle.

Electromagnetic flow meters detect flow by using faraday s law of induction. The operation principle behind the electromagnetic blood flow meters is far aday s law of electromagnetic induction which states that if electrical current carr ying conductor moves at right angle. 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.

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 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. These meters are also called as magflow or electromagnetic flow meters. Principle of electromagnetic blood flow meters a permanent magnet or electromagnet positioned around the blood vessel generates a magnetic field perpendicular to the direction of the flow of the blood.

The induced voltage e is directly proportional to the velocity v of the fluid moving through the magnetic field b. Https eh digital 2pupwrw illustration of the ultrasonic flow measuring principle.
