Both electrodes must be wetted by the medium� Otherwise the signal
[SEnS] for empty pipe is provided, if empty pipe detection is enabled�
4.2 Processing of the measured signals
The unit displays the current process values�
It generates 2 output signals according to the parameter setting�
OUT1/IO-Link: 5 selection options
Parameter setting
-Switching signal for volumetric flow limit values (→ 10.3.1)
-or frequency signal for volumetric flow quantity (→ 10.3.4)
-or pulse signal for quantity meter (→ 10.4.1)
-or switching signal for preset counter (→ 10.4.2)
-or switching signal for empty pipe detection (→ 10.6.9)
OUT2: 6 selection options Parameter setting
-Switching signal for volumetric flow limit values (→ 10.3.2)
-or switching signal for temperature limit value (→ 10.5.1)
-or analogue signal for volumetric flow quantity (→ 10.3.3)
-or analogue signal for temperature (→ 10.5.2)
-or input for external reset signal (InD) (→ 10.4.6)
-or switching signal for empty pipe detection (→ 10.6.9)
4.3 Volumetric flow monitoring
4.3.1 Volumetric flow quantity
The signals for measuring the volumetric flow quantity can be provided as follows:
1� Two switching signals for volumetric flow quantity limit values on output 1 and
output 2. On the switching functions → 4.7.
2� A frequency signal (10 Hz...10 kHz) on output 1. On the frequency functions →
4�9�
3� An analogue signal (4���20 mA or 0���10 V) on output 2� On the analogue
functions → 4.8.
4.3.2 Direction of flow
In addition to the flow velocity, the unit also detects the flow direction� An arrow on
the unit indicates the positive flow direction�
The flow direction can be inversed (→ 10.6.3).
