Mounting
Flow measuring section
The mounting orientation is optional, the mounting location (heat or cold side) must
correspond to the meter type.
On heat energy meters or combined heat/cooling energy meters, the mounting location of
the cooling side corresponds to the return and the mounting location of the heating
side to the flow .
On cooling energy meters, the mounting location of the heating side corresponds to the
return and the mounting location of the cooling side to the flow .
On meters with adjustable mounting location 'P', the mounting location, heat side, is
displayed as 'hot'. The mounting location, cooling side is displayed as 'cold'.
NOTICE
The mounting location is locked and can no longer be changed once the meter recognizes
a volume of 10 liters. After that, 'P' is no longer displayed: 'hot' or 'cold'.
Settling paths are not required, neither upstream of nor downstream from the meter. If the
meter is installed in the common return of 2 heating circuits, the mounting location must be
at an adequate distance from the T-piece (min. 10 x DN) to allow the different water
temperatures to properly mix.
Thoroughly flush the plant prior to installing the meter.
Mount the flow measuring section between 2 shutoff valves with the arrow pointing in the
direction of flow. The sensors must be mounted in the same water circuit as the flow
measuring section (observe mixing). Do not separate, shorten, or extend the lines. The
sensors can be fitted in T-pieces or ball valves, or can be immersed, either directly or in
pockets (observe all national regulations). In any case, the end of the sensors’ probe must
extend to at least the pipe center. Temperature sensors and fittings must be sealed to
prevent tampering.
NOTICE
● Comply with all local mounting regulations for meters when mounting the meter.
● Protect the meter against damage from shocks and vibrations at the mounting location.
● Ensure that no water can enter the processor unit at the mounting location.
