Depending on the application (heat or cooling meter), the energy
meter is installed in the forward or return pipe of the system. The
installation location is printed on the meter and is also visible in the
information loop in the calculator menu. The ow sensor must be
installed so that the direction of ow corresponds to the direction
of the arrow on the sensor. Calming sections are not needed before
or after the energy meter, but calming sections of 3xDN are recom-
mended before the meter.
The energy meter can be installed in both horizontal and vertical pipe
sections, but every time so that air bubbles cannot collect in the meter.
The ow sensor must always be lled with water. Avoid frost on the
meter.
We recommend installing the ow sensor in a tilted (45°) position.
The minimum system pressure must be 1 bar to avoid cavitation.
Make sure the energy meter is installed suciently far away from
possible sources of electromagnetic interference (switches, electric
motors, uorescent lamps, etc...).
To simplify the removal of the energy meter it is recommended to
install isolating valves before and after the meter.
The energy meter should be installed in an accessible position for
service and operating personnel.
Initial operation is to be carried out and recorded after installation.
For medium temperatures of more than 90°C or if T

(for application as cooling meter or heat meter with cooling tari),
the calculator must be removed from the meter and installed
asucient distance away from heat sources.
A wall holder (supplied with meter) or a space holder (optional) is
available for this purpose.
