4.6 Volumetric flow monitoring / analogue function
• The analogue start point [ASP] determines at which measured value the output
signal is 4 mA�
• The analogue end point [AEP] determines at which measured value the output
signal is 20 mA�
Minimum distance between [ASP] and [AEP] = 25 % of the final value of the
measuring range�
Factory setting
Measuring range scaled
MEW = final value of the measuring range
In the set measuring range the output signal is between 4 and 20 mA�
It is also indicated:
• Volumetric flow above the measuring range: output signal > 20 mA�
• Flow rate below the measuring range: output signal between 3�6 and 4 mA�
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 unit must be mounted before the oiler�
