MAGYN Serials Intelligence Electromagnetic Flow Meter conducts measurement based on the principle of the Faraday Electromagnetic Induction Law. When conductive liquid flows in a magnetic field and incises the magnetic flux, there generated induced electromotive force E in the conductor, as below.
E=KBVD
Where,
k--------Instrument constant
B--------Magnetic induction density
V--------Average velocity in the cross section of a measured pipe
D--------Inner diameter of a measured pipe
When measuring a flow rate, the conductive liquid flows at a velocity of V perpendicularly through a magnetic field, which inducts a voltage that is direct proportional to the average velocity. The inducted voltage signal is measured on two or more poles immediately contacted with the liquid, sent to a convertor through a cable, and then intelligentized before it is transferred to and displayed in a LCD or converted into a 4¡«20mA or 0¡«1kHz output.
