SENSOR FLOMAT-FX
1 WORKING PRINCIPLE
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.
2 RECEPTION
The FLOMAT electromagnetic flowmeters are supplied conveniently packaged for
transportation together with their instruction manual for installation and operation.
All the flowmeters have been verified in our calibration rigs to obtain the gain factor Fc for
each sensor.
2.1 Unpacking
Unpack the instrument carefully, removing any remains of the packing.
2.2 Storage temperature
-20ºC ...... +60ºC
V = B·v·d
Where:
V = Measured voltage in the electrodes
B = Magnetic field
v = Liquid velocity
d = Distance between electrodes
