3  Functions and features

The unit monitors the standard volume flow of operating compressed air�

It detects the 3 process categories volumetric flow, consumed quantity, medium 

temperature�
Applications: compressed air equipment�

All data refer to standard volume flow according to DIN ISO 2533, i�e� volume flow 

at 1013 hPa, 15°C and 0% relative air humidity�
The general operating conditions of compressed air equipment apply�
Pressure Equipment Directive (PED): Devices with a measuring section comply 

with art� 3 sec� (3) of the Directive 97/23/EC and are designed and manufac-

tured for stable gases of the fluid group 2 in accordance with sound engineering 

practice�

4  Function

4.1  Processing of the measured signals

•  The unit displays the current process values�

•  It generates 2 output signals according to the parameter setting�

OUT1: 3 selection options �����������������������������������������������������  parameter setting

switching signal for volumetric flow limit values  ���������������������������������� (→ 9.2.1)

or pulse sequence for totalising meter  ������������������������������������������������ (→ 9.3.1)

or switching signal for preset counter  ������������������������������������������������� (→ 9.3.2)
OUT2: 2 selection options

switching signal for volumetric flow limit value  ����������������������������������� (→ 9.2.2)

or analogue signal for volumetric flow  ������������������������������������������������ (→ 9.2.3)

4.2  Volumetric flow monitoring

The flow rate is monitored by a calorimetric measuring system, the measured 

signals by the electronics�

•  2 switching signals for volumetric flow limit values can be provided (output 1 

and output 2). For the switching functions → 4.5.

•  An analogue signal proportional to the volumetric flow (4���20 mA) can be 

provided on output 2. For the analogue functions → 4.6.
