2. INSTALLATION OF ENERGY METER
Depending on the design and application (heat or cooling meter),
the energy meter is installed in either the hot or cold line of the
system. The programmed installation location is shown in the
information loop. The flow sensor must be installed so that the
direction of flow corresponds to the direction of the arrow on the
sensor. Calming sections are not necessary before and after the
flow sensor, but calming sections of 3xDN are recommended
before the meter. The meter can be installed in both horizontal
and vertical pipe sections, provided air bubbles cannot collect in
the meter. The flow sensor must always be filled with liquid.
We recommend installing the flow sensor in a tilted position. The
minimum system pressure must be 0,5 bar to avoid cavitation.
