5.2.5 Function and application

The flow sensor uses the calorimetric measuring principle. The sensor measures
the cooling effect of the medium flowing over the heated probe.
The higher the flow speed of the medium, the higher the cooling effect of the
heated probe.
In the IO-Link variant, the sensor has two configurable switch outputs Q1 and Q2
for flow, pressure, or temperature. Additionally, an IO-Link interface is provided
at switch output Q1.
The flow sensor is particularly suited for the following purposes:
• Measuring compressed air and non-corrosive and non-ignitable gases in ma-
chines
• Monitoring the energy consumption of compressed air on machines and in
the pressure distribution system
• Monitoring leaks in compressed air lines on machines
• Measuring inert gases in the packaging of foodstuffs
