Notes
Installation
Flow measuring section
The meter can be mounted in any position (exception: installation above head is not
allowed). The installation location (return or flow) is based on meter type. Inlet or outlet
settling paths are not required. If the meter is installed in the common return of 2 heating
circuits (e.g. space heating and DHW), 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.
The system must be properly flushed before installing the meter.
Mount the flow measuring section between 2 shutoff valves with the arrow on the measuring
section pointing in the direction of flow. The sensors must be mounted in the same water
circuit as the flow measuring section (observe mixing). The sensors can be fitted in T-pieces,
ball valves, direct immersed or in pockets (national regulations must be observed). In any
case, the end of the sensors must extend to at least the pipe center. Temperature sensors
and fittings must be sealed to prevent tampering.
