INSTALLATION
HYDRAULIC PART
BEFORE MOUNTING
Before the 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.
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.
It is necessary to pay attention to the direction of the flow. Install the meter according to the water
flow following the direction indicated by the arrow embossed on the meter body. Install the meter
respecting the position designation (in accordance with the indication on the lid of the meter itself).
To ensure a correct measurement, make sure that there is no air inside of the pipe and make sure that
there are no debris in the fluid (potentially dangerous for the turbine of the meter).
MOUNTING
Always respect the type of installation prescribed (inlet pipe\outlet pipe). Always refer to the
information reported on the lid of the meter.
The picture below refers to a typical installation of a heat meter, standard version (return pipe
installation) and horizontal mounting.
