Notes on safety
The Durchflusssensor has been manufactured according to the accepted rules of safety and
current technology. There is, however, still a danger of personal injury or damage to equipment
if the following general safety instructions and the warnings before the steps contained in these
instructions are not complied with.
O
Read these instructions completely before working with the Durchflusssensor.
O
Keep these instructions in a location where they are accessible to all users at all times.
O
Always include the operating instructions when you pass the Durchflusssensor on to third
parties.
Intended use
O
Only use the Durchflusssensor to measure the flow of compressed air (Air), Argon, Helium,
carbon dioxide (CO2) and gaseous nitrogen (Nitrogen) for industrial applications in
accordance with the technical information.
O
Use within the limits listed in the technical data.
O
The device is designed to be installed in AS series maintenance units or to be fitted as a
stand-alone device using mounting brackets.
Intended use includes having read and understood these instructions, especially chapter "Notes
on safety".
Improper use
It is considered improper use if the Durchflusssensor
W
is used in hydraulic systems or comes into contact with aggressive/explosive/flammable/
poisonous gases or liquids,
W
any modifications are made to the device,
W
or is used for accounting purposes in business dealings, for example measuring air
consumption in supply equipment.
SIGNAL WORD
WARNING
CAUTION
Personnel qualifications
Assembly, disassembly, commissioning, and operation of the Durchflusssensor require basic
electrical and pneumatic knowledge, as well as knowledge of the appropriate technical terms.
Assembly, disassembly, connection, commissioning, and operation may therefore only be
carried out by qualified electrical or pneumatic personnel or an instructed person under the
direction and supervision of qualified personnel.
Qualified personnel are those who can recognize possible hazards and institute the appropriate
safety measures, due to their professional training, knowledge, and experience, as well as their
understanding of the relevant regulations pertaining to the work to be done. Qualified personnel
must observe the rules relevant to the subject area.
General safety instructions
W
Observe the regulations for safety, accident prevention and environmental protection for the
country where the device is used and at the workplace.
W
Do not modify or convert the flow rate sensor. The manufacturer can accept no liability
claims if these instructions are not complied with or the device is interfered with; the
warranty for appliances and accessory parts will no longer apply.
W
All settings on the flow rate sensor, all assembly and disassembly work, and commissioning
may only be performed by trained personnel.
W
Do not loosen any connecting cables or tubing if systems are under voltage or pressure!
W
Do not place any deflection, torsion, or impact loads on the flow rate sensor.
W
Make sure that the stipulated air quality class for the flow medium is observed. Any
impurities in the compressed air can damage the device and lead to inaccurate
measurements and functional defects. Furthermore, unintended signals may result in
personal injury or damage to equipment.
W
Flow measurement in the Durchflusssensor only works properly when AVENTICS connecting
cables (series CON-RD - M12x1) are used (see online catalog).
O
Execute the wire cross-sections of the supply cable supplied by the user in accordance with
the applicable standards. Observe the following standards in Germany:
DIN VDE 0100 (Part 430) and DIN VDE 0298 (Part 4), or DIN VDE 0891 (Part 1).
O
Implement power circuits connected to the device as SELV and PELV circuits (SELV = Safety
Extra Low Voltage, PELV = Protective Extra Low Voltage).
During assembly and commissioning
W
Make sure the relevant system component is not under pressure or voltage before
assembling or disassembling the flow rate sensor.
W
Make sure that the connected compressed air lines are free of particles and that no fluids
can penetrate the device through them.
W
Do not install any obviously damaged devices and exchange defective devices immediately.
W
Check if the device measurement range (see "13 Technical Data") corresponds to the
maximum flow at the intended installation location.
During operation
W
Immediately exchange the Durchflusssensor if any malfunctions occur.
W
Make sure that permitted temperature and pressure levels are not exceeded.
W
Do not change the sensor/filter combination as this would render calibration obsolete.

About This Product
The flow rate sensor is available in two versions:
W
IO-Link version
W
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 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:
W
Measuring compressed air and non-corrosive and non-ignitable gases in machines
W
Monitoring energy consumption of compressed air on machines and in the pressure
distribution system
W
Monitoring leaks in compressed air lines on machines
W
Measuring inert gases in food packaging
