Following Faraday's law of magnetic induction, a voltage is induced in a conductor moving through a magnetic field.

Ue: Induced voltage
B: Magnetic induction (magnetic field)
L: Electrode spacing
I: Current
v: Flow velocity

In the electromagnetic measuring principle, the flowing medium is the moving conductor. The voltage induced (U e ) is proportional to the flow velocity (v) and is supplied to the amplifier by means of two measuring electrodes. The flow volume (Q) is calculated via the pipe cross-section (A). The DC magnetic field is created through a switched direct current of alternating polarity.

• Induced voltage Ue = B · L · v
• Volume flow Q = A · v

The device consists of a transmitter and a sensor.

Two device versions are available:

• Compact version – transmitter and sensor form a mechanical unit.
• Remote version - transmitter and sensor are mounted in separate locations.
