WORKING PRINCIPLE
The FLOMID electromagnetic flowmeters converter 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.

RECEPTION
The FLOMID electromagnetic flowmeters are supplied conveniently packaged for their
protection during transportation and storage, together with their instructions manual for
installation and operation.
All the instruments are supplied tested in our flow rigs, obtaining the gain factor Fc of 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.
