TEMPERATURE SENSOR INSTALLATION
INSTALLATION IN A SOCKET
All versions of the thermal energy meter can be installed both horizontally and vertically. For a better performance
it is preferable, however, the horizontal installation with the turbine axis perpendicular to the ground and the reading
mechanism facing upwards.
The thermal energy meter is equipped with two digital probes that comply with the MID 2014/32/EC directive and the
EN1434 standard.
1. Screw the socket in the pipe
2. Insert the temperature sensor
3. Tighten the screw
In the standard version (e.g mounting on return pipe), the return probe is already incorporated inside the brass case.
The supply probe must be installed in a ball valve or in a socket mounted on the flow pipe and complies with the
requirements of the sensor itself.
Vice versa, the version for installation on the inlet pipe the probe inserted inside the brass case will be the flow, the
return probe will need to be installed in a valve or a socket on the return pipe.
Ideal position
