5 Installation
The rules and regulations for the installation and operation of compressed
air equipment must be observed�
5.1 Installation location
• Behind the cold dryer / near the load�
• If compressed air is fed into the main pipe through parallel pipes, the unit
should be mounted in the main pipe�
• Installation after the maintenance unit is also possible (if oil is used for the
loads, the units must be mounted before the oiler)�
5.2 Installation conditions
To achieve the specified measurement accuracy, the following installation condi-
tions must be adhered to: defined inlet and outlet pipe lengths, defined flow cross-
section area, fixed installation depth and correct positioning of the measuring
elements�
The unit is mounted in a measuring range which meets these conditions�
In case of disturbances on the inflow side additional calming sections (B) are
recommended:
changes to the pipe diameter B = 5 x pipe diameter
90° elbow B = 5 x pipe diameter
two 90° elbows, one plane B = 10 x pipe diameter
two 90° elbows, two planes B = 15 x pipe diameter
valve, slide B = 35 x pipe diameter
