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).
