Installation in down pipes
Install a siphon or a vent valve downstream of the sensor in down pipes whose length h  5m
(16.4 ft), (→  5). 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 air pockets.
