6.1 Installation conditions
No special measures such as supports are necessary.
6.1.1 Mounting position
Mounting location
Thermal measuring devices require a fully developed flow profile as a prerequisite for
correct flow measurement. For this reason, please pay attention to the following
points and document sections when installing the device:
• Avoid flow disturbances, as the thermal measuring principle reacts sensitively to them.
• Take measures to avoid condensation (e.g. condensation trap, thermal insulation etc.).
Orientation
The direction of the arrow on the sensor helps you to install the sensor according to the
flow direction (direction of medium flow through the piping).

1) In the case of saturated or unclean gases, upward flow in a vertical pipe section is preferred to minimize
condensation or contamination.
2) Suitable only for clean and dry gases. If buildup or condensate are always present: Mount the sensor in an
inclined position.
3) Select inclined mounting position (α = approx. 135°) if the gas is very wet or saturated with water.
