3. Installation of energy meter
• Calming sections are not necessary before and after the flow sensor. For systems without temperature mixing,
a straight DN 3 - 10 section upstream of the flow sensor is recommended.
The meter can be installed in both horizontal and vertical pipe sections, provided air bubbles cannot coll-
ect in the meter. The flow sensor must always be filled with liquid. Avoid frost at the meter.
• We recommend installing the flow sensor in a tilted position.
• The minimum system pressure must be 1 bar to avoid cavitation.
• Make sure the meter is installed sufficiently far away from possible sources of electromagnetic interference
(switches, electric motors, fluorescent lamps etc.).
• If possible install the cables of the flow sensor or temperature sensor freely suspended (not bundled - aerial
effect) with sufficient distance from electromagnetic interference sources.

• For medium temperatures from 90°C or for T
tariff application) the calculator must be removed and fitted at a sufficient distance from any heat sources. A
wall holder (supplied with meter) or a spacer holder (optional) is available for this purpose.
