of sharp edges.
Assembly and disassembly only in depressurised system.
The meter is to be protected against damages due to impacts
and vibrations.
The pipelines are to be attached before and behind the meter.
Pipes for measuring signals are to be installed far away from
other power lines.
When choosing the installation location, make sure that the
meter is perfectly accessible for service and operating personnel.
It is recommended that shut-off valves are fitted before and after
the meter to simplify removing the meter.

1. Rinse the conduit thoroughly.
2. Close the stop valves upstream and downstream of the meter and
depressurise the pipeline.
It is recommended to install a dirt trap in front of the flow sensor
or at another suitable position of the circulation.
No inlet or outlet path is necessary for the installation of a flow
sensor.
With heating systems without temperature mixing or temperature strati-
fication, the pre-connection of a feeding length of 3-10 DN in front of the
meter is recommended.
