It is recommended to select meter installation place as far as possible from potential sources of
vibration (for example, pumps).
The gaskets must match with the pipe diameter. During the installation gasket must be exactly centered
with the center of the pipe cross-section to avoid sticking out gaskets inside the pipe.
Checking of installation and parameter setting
If the meter is installed correctly, when there is flow, the display of the meter should display flow readings.
It is necessary to check whether the meter is installed in the correct direction, whether there is no air in the
system.
