15.2
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’.
15.3
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.
Regulating valves and pumps cause heavy flow disturbances and large amounts of air in the water, meaning that a
shut-off valve, placed immediately in front of the meter, must only be fully open or fully closed. Therefore, flow
regulation and pressure reduction must only be done after the meter.
15.4
Operating pressure
In order to avoid formation of air bubbles or vapor dents in the meter (cavitation)
–
and to ensure correct
measurement under all circumstances
–
the operating pressure in the pipe installation, immediately after the meter
(the downstream), must always be minimum 0.2 MPa (2 bar).
