3 Intended use

The unit monitors liquid media (water, glycol solutions, industrial oils, coolants).

It detects the volume flow (flow rate/time) and outputs an analogue signal that is proportional to the
process value.

ATTENTION

Frost formation of the medium.

The sensor may be damaged.

Ensure that the medium in the sensor does not freeze during operation and transport.
