Partially filled pipes
Partially filled pipes with gradients necessitate a drain-type configuration. The Empty Pipe Detection (EPD)
function offers additional protection by 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.

Vertical pipes
Install a siphon (b) or a vent valve (a) downstream of the sensor in vertical 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.
These measures also prevent the system losing prime, which could cause air inclusions. Information on the lin-
ing’s resistance to partial vacuum can be found on Page 21.
