Permissible operating conditions
Ambient temperature:
2…55 °C – indoors or outdoors.
Installation in direct sunlight ought to be avoided.
Temperature of media:
0.1…70 °C
System pressure:
0.3 …16 bar (depending on couplings/gaskets)
9.1.3
EMC conditions
The water meter is designed for installation in housing and meter pits, as well in commercial and industrial
buildings. The meter is CE-marked according to MID on the basis of OIML R49 type test class E1 and E2, as
well as the Low Voltage Directive. CE-marking applies to Europe only.
9.1.4
Service
When the water meter has been mounted in the system, neither welding nor freezing is allowed. Dismount
the meter from the system before starting such work.
In order to facilitate replacement of the meter, closing valves should be mounted on both sides of the
meter. Under normal operating conditions no pipe strainer is required in front of the meter.
9.2
Installation angle
The meter can be mounted at all angles and in all positions. Thus, the meter can be mounted in a usual
horizontal installation. It can be mounted vertically in an ascending pipe, it can be mounted at any angle
and it can be mounted with its display pointing downwards, e.g. under a ceiling. Mounting the meter in a
downpipe, you must be aware that the display will in that case be ‘upside down’.
9.3
Straight inlet
The meter requires neither straight inlet nor straight outlet to meet the Measuring Instruments Directive
(MID) 2004/22/EC and OIML R49. A straight inlet section will only be necessary in case of heavy flow
disturbances before the meter.
