About This Product 2

The flow rate sensor is available in two versions:

IO-Link version
Ethernet version

Principle of operation
The flow rate sensor employs the calorimetric measuring principle. The sensor measures the cooling effect of the medium flowing over the heated probe. The higher the flow velocity of the medium, the higher the cooling effect on the heated probe.
The sensor has two configurable switch outputs Q1 and Q2 (only for the IO-Link version) for flow, pressure, or temperature.
In addition, an IO-Link interface is available at the switch output (Q1).
Applications
The flow rate sensor is particularly suitable for:

Measuring compressed air and non-corrosive and non-ignitable gases in machines
Monitoring 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 food packaging

The dimensions for the flow rate sensor can be found in Fig. 1/1 and 1/2.

Assembly

CAUTION
The danger of injury from uncontrolled operation
If the system is under voltage and/or pressure during the assembly of the Durchflusssensor, this may lead to uncontrolled responses and, as a result, to injuries to personnel or damage to the system.

Always make sure the relevant system component is not under pressure or voltage before connecting pneumatics or electrics for the Durchflusssensor.

Installation Conditions

Make sure that the assembly location is easy to access and free from vibrations.
Observe a minimum free space of 150 mm for the transmitter unit of the flow rate sensor.
Observe the ambient temperature (see “13 Technical Data”) and the heat dissipated by the measuring medium.
The measuring medium must at least correspond to purity class 3:4:4 or better, in accordance with ISO 8573-1:2010.
The measuring medium and the ambient air must not condensate.
