OVERVIEW:
The operation of electromagnetic flowmeters hinges upon Faraday’s Law of Electromagnetic Induction. This fundamental law states that as a conductor traverses a magnetic field, a voltage, termed electromotive force (EMF), is induced across it. This EMF is oriented perpendicular to both the conductor’s direction of motion and the orientation of the magnetic field,The magnitude of the induced EMF is directly proportional to the velocity of the conductor’s motion and the strength of the magnetic field.
