Preferably install the sensor in an ascending pipe, and ensure a sufficient distance to the
next pipe elbow: h ≥ 2 × DN
Installation in down pipes
Install a siphon with a vent valve downstream of the sensor in down pipes whose length 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.
