2 Safety instructions
• The unit described is a subcomponent for integration into a system.
– The system architect is responsible for the safety of the system.
– The system architect undertakes to perform a risk assessment and to create documentation in
accordance with legal and normative requirements to be provided to the operator and user of
the system. This documentation must contain all necessary information and safety instructions
for the operator, the user and, if applicable, for any service personnel authorised by the
architect of the system.
• Read this document before setting up the product and keep it during the entire service life.
• The product must be suitable for the corresponding applications and environmental conditions
without any restrictions.
• Only use the product for its intended purpose (Ò Intended use).
• Only use the product for permissible media.
• If the operating instructions or the technical data are not adhered to, personal injury and/or damage
to property may occur.
• The manufacturer assumes no liability or warranty for any consequences caused by tampering with
the product or incorrect use by the operator.
• Installation, electrical connection, set-up, operation and maintenance of the product must be
carried out by qualified personnel authorised by the machine operator.
• Protect units and cables against damage.

3 Intended use
The device monitors liquids and gases.
The device detects flow based on the calorimetric measuring principle and switches the output.
The switch point is adjustable.
The typical response time of the device is 1 ... 10 s. It can be influenced by the setting of the switch
point:
• Low switch point = quick reaction with rising flow.
• High switch point = quick reaction with falling flow.

4 Installation
CAUTION
During installation or in case of mechanical failure, high pressure or hot media can leak
from the system.
wRisk of injury caused by pressure or burns.
uEnsure that the system is free of pressure during installation.
uEnsure that no media can leak at the mounting location during installation.
4.1 Installation position
4.1.1 Immersion depth
≥12 mm
Fig.1: Immersion depth
• The sensor tip must be completely surrounded by the medium.
• Recommended immersion depths: minimum 12 mm.
4.1.2 Recommended mounting position
Fig.2: Recommended mounting position
• For horizontal pipes: mounting from the side.
• For vertical pipes: mounting in the rising pipe.
4.1.3 Conditionally possible installation position
Fig.3: Conditionally possible installation position
• For horizontal pipes, if the pipe is free from build-up: mounting from below.
• For horizontal pipes, if the pipe is completely filled with medium: mounting from the top.

4.1.4 Impermissible installation position
Fig.4: Impermissible installation position
• The sensor tip must not be in contact with the pipe wall.
• Do not mount in downpipes that are open at the bottom.
4.2 Interference
Structures in the pipe, bends, valves, reducing pieces and the like affect the function of the unit.
uAdhere to the distances between sensor and interference.

4.3 Process connection
Using process adapters the unit can be adapted to different process connections.
A correct fit of the unit and ingress resistance of the connection are only ensured using ifm adapters.
For small flow rates, ifm adapter blocks are available.
The device is supplied without accessories.
Information about available accessories at documentation.ifm.com.
The optimum function is not ensured when using components from other manufacturers.

uGrease the threads of the process connection, adapter and sensor. Use a lubricating paste which
is suitable and approved for the application.
Ensure no grease is applied to the sensor tip.
uScrew the suitable adapter into the process connection.
