Measuring principle
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.
Formulae for calculation
Induced voltage Ue = B · L · v
Volume flow Q = A · v
Measuring system
The device consists of a transmitter and a sensor.
The device is available as a compact version:
The transmitter and sensor form a mechanical unit.
