1 INTRODUCTION
The FLOMAT electromagnetic flowmeters are based on Faraday’s induction law.
When an electrically conductive liquid flows through a magnetic field, perpendicular to the
flow direction, it induces a voltage V proportional to the liquid velocity.
Two electrodes in contact with the liquid and positioned perpendicularly to the magnetic
field, sense this voltage V.
The electronic converter is based on the most advanced technology in digital signal
processing, in order to obtain accurate and reliable measurements.
The device provides the following features:

Coil excitation by means of pulsed signal to obtain a negligible zero offset.

Pulse and current output proportional to the flow rate and user programmable.
V = B·v·d
Where:
V = Measured voltage in the electrodes
B = Magnetic field
v = Liquid velocity
d = Distance between electrodes
