16 Technical data
16.1 Application
The measuring device is only suitable for flow measurement of liquids with a minimum
conductivity of 5 µS/cm.
Depending on the version ordered, the measuring device can also measure potentially
explosive, flammable, poisonous and oxidizing media.
To ensure that the device remains in proper operating condition for its service life, use the
measuring device only for media against which the process-wetted materials are
sufficiently resistant.
16.2 Function and system design
Measuring principle Electromagnetic flow measurement on the basis of Faraday's law of magnetic induction.
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.
