Partially filled pipes
Partially filled pipes with gradients necessitate a drain-type configuration. The Empty Pipe Detection
function offers additional certainty in detecting empty or partially filled pipes.

Caution!
Risk of solids accumulating. Do not install the sensor at the lowest point in the drain. It is advisable
to install a cleaning valve.

Installation in partially filled pipe
Down pipes
Install a siphon or a vent valve downstream of the sensor in down pipes longer than 5 meters. This
precaution is to avoid low pressure and the consequent risk of damage to the lining of the measuring
tube. This measure also prevents the system losing prime, which could cause entrained air.
