4 Function
•
The unit detects the volumetric flow based on the measuring principle of ultrasonic transit time
difference.
•
As additional process value the unit detects the medium temperature.
•
The unit displays the current process values.
•
The unit can be operated in SIO mode (standard input-output ) or in IO-Link mode.
•
The unit has many self-diagnostic options.
– Monitoring of the flow direction
– Monitoring of the signal quality
– Indication of warnings and error messages
•
The unit indicates all self-diagnostic options through the colour signal of an operating status LED.
In addition, the diagnostic information is provided via the outputs and the IO-Link interface.
•
A simulation mode allows simplified set-up of the sensor.
