FEM1000 - Integrated

The operation of FEM1000 is based upon Faraday's Law, which states the voltage(E) induced across any conductor as it moves at right angles through a magnetic field(B) is proportional to the velocity(V) of that conductor.

E=KBVD

K = Constant.
B = The magnetic field strength.
V = The velocity of the conductive medium.
D = The distance between probes.

The voltage generated in a conductor E is output as standard electrical signal.

 Characteristics
