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 Fc factor for each
sensor.
2.1 Unpacking
Unpack the instrument carefully, removing any remains of the packing from the inside of
the sensor. Do not remove the grease from the neck that couples to the electronics
housing.
2.2 Storage temperatures
-20ºC ...... +60ºC
3 HANDLING
It should always be done with care and without knocks.
V = B·v·d
Where:
V = Measured voltage in the electrodes
B = Magnetic field
v = Liquid velocity
D = Pipe diameter
