Burkert 8041 - Operating Principle

Description
5.2.2. Operating principle
The magnetic system in the ow sensor generates a magnetic
eld in the uid, perpendicular to the ow direction, see Fig.1.
The electrodes on the ow sensor ensure electrical contact with
the uid. When the uid ows over them, a voltage is measured
between the two electrodes. This voltage is proportional to the
uid velocity.
