BEFORE INSTALLATION
3. Installation
Before the thermal energy meter installation make sure that the two ends of the inlet and outlet
pipe are perfectly aligned, clean them with the utmost care. Moreover, make sure there is a suitable
filter placed at the inlet and that clean and undamaged gaskets are inserted on both sides. The
thermal energy meters must be installed as specified by the CEN-TR 13582 regulation. Upstream
and downstream the meter install an appropriate water flow interception and regulation devices
suitable to allow inspection and maintenance of the meter, control of the water flow and eventual
sealing of the system.
Attention should be paid to the direction of flow. Install the thermal energy meter so that the
passage of water takes place in the direction indicated by the arrow in relief on the brass body and
respecting the prescribed position.
To ensure proper measurement, make sure that there is no air inside the pipe and that the flow is
clean and free of debris (potentially harmful to the meter turbine).
INSTALLATION
It is mandatory to comply with the prescribed
type of assembly (return pipe\supply pipe).
Always refer to what is on the meter menu 3
level 06. The figure below refers to a standard
version of the device installation (mounting on
return pipe) and positioned horizontally.
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.
Ideal position for a
better performance
Additional allowed positions
* This position is not suggested for cooling meters and in cases where moisture can enter the electronic
casing due to condensation (e.g. during an interruption of the plant in the summer)
