Partially filled pipes
Partially filled pipes with gradients necessitate a drain-type configuration.
Installation with partially filled pipes
Down pipes
Install a siphon or a vent valve downstream of the sensor in down pipes h ≥ 5 m (16,4 ft). This
precaution is to avoid low pressure and the consequent risk of damage to the measuring tube. This
measure also prevents the system losing prime, which could cause air pockets. Information on the
pressure tightness of the measuring tube →  15, section "Pressure tightness".

Vertical
Vertical orientation is generally preferred. Vertical
orientation helps avoid gas and air accumulations and
deposits in the measuring tube.

Horizontal
The measuring electrode axis should be horizontal in
the case of horizontal orientations. This prevents
brief insulation of the two measuring electrodes by
entrained air bubbles.
