 25 Installation of the sensor after a control valve is not recommended
1 Control valve
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.
