Notes
Mounting
Flow measuring section
Compare the mounting location with the symbol on the LCD ( or ) to determine the
mounting location. Adapt the mounting location to local conditions as needed. 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 .
NOTICE
The mounting location can be changed in the field. The function locks after 5 changes and
can no longer be used. Entries can be checked in the LCD loop 'LE'. As an alternative, the
mounting location can also be changed with the service software 'UltraAssist'.
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.
