3  Functions and features

The unit monitors liquids�

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

temperature�

Application area

Conductive liquids with the following properties:

•  conductivity: ≥ 20 µS/cm

•  viscosity: < 70 mm

2

/s at 40 °C

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: 4 selection options

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

or switching signal for temperature limit value ����������������������������������������� (→ 9.4.1) 

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

or analogue signal for temperature ���������������������������������������������������������� (→ 9.4.2)
OUT2 (pin 2) cannot only be used as an output

but also as an input for an external reset signal:

 

 ������������������������������������� (→ 9.3.5)

4.2  Volumetric flow monitoring

The medium flows through a magnetic field� It generates a signal voltage which is 

directly proportional to the volumetric flow�
•  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 or  0���10 V) 

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

In addition to the flow velocity, the unit also detects the flow direction� The positive 

flow direction is marked on the unit by an arrow (“flow direction” → 5.2).
