Installation
Based on the dimension drawings, choose a
mounting location with sufficient clearance. Mount
the volume measuring unit between two shut-off
valves in accordance with the arrow on the volume
measuring unit for the direction of flow.
No inlet or outlet sections are necessary. However, if
the meter is installed in the shared return of two
systems, the mounting location must be a sufficient
distance from the T element that forms the junction

temperatures to mix well.
The sensor can be mounted in ball valves or in
pockets. The sensors must be inserted at least up to
the center of the pipe cross-section.

If the water temperature is below 10° C or above
90° C, a split mounting is necessary. In this case the
electronic unit is to be mounted separately from the
volume measuring unit.
A meter with a removable control cable may be
separated during the installation. When installation is
done be sure that only paired parts (volume part,
calculator) are connected together.

Mounting as a cold meter
When mounting a cold meter or combined
heat/cold meter, make sure the black cover on the
measuring tube is oriented to the side or downward
(because of water condensation). The immersion
sleeves should also mounted to the side or
downwards.
The electronic unit must be separated from the
flowrate measuring tube and, for example, mounted
on the wall (split mounting). Make sure that
condensed water cannot run along the connected
water
pipes into the electronic unit (building a loop
downwards).

The service button and calibration contact are not
accessible until the housing cover is removed.
The calibration contact is additionally protected by a
security seal.
The optical interface permits data communication via
a computer with the necessary service software.
