3 Functions and features

The unit monitors liquids�
It detects the 3 process categories volumetric flow, consumed quantity, medium
temperature�
Applications:
• Water
• Glycol solutions
• Oils (viscosity: viscosity: ≤ 68 cSt at 104°F / ≤ 68 mm²/s at 40°C)
Selection of the medium to be monitored → 9.5.9.

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 flow rate is monitored by an ultrasonic meter, 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 or 0���10 V)
can be provided on output 2. For the analogue functions → 4.6.
