2.2 Special safety instructions
To avoid damage to the flow sensors and the monitored system, only use our flow sensors to measure
liquid flows.
Prior to installation, ensure whether the material of the flow sensor is suitable for the medium to be
measured.
In order to achieve accurate measurements, only use liquids with a minimum conductivity of 50 μS/cm.
Ensure that the maximum specified operating pressure is not exceeded.
Never remove a flow sensor from a pipe system under pressure.
Ensure that the maximum specified operating temperatures are not exceeded.
Select suitable measures to prevent the medium from freezing in the flow sensor.
Protect the flow sensor against external magnetic fields in the immediate vicinity, since these can impair
device functioning.
Caution: Voltage Hazard!
Always de-energize the system before connecting the connector cable.
It is prohibited to remove or make product labels or any other information attached to the equipment
indecipherable, otherwise all warranties and the responsibility of the manufacturer no longer apply.
