4 Mounting
If you cannot maintain this distance, you should carry out a false
signal storage during setup. This applies particularly if buildup on the
vessel wall is expected. In such cases, we recommend repeating the
false signal storage at a later date with existing buildup.
Inflowing medium Filling from the top: Mounting should not be too close to the inflow-
ing material as the microwave signal will be interferred. The optimum
mounting position is on the opposite of the filling. To avoid strong
pollution, the distance to the filter or dust extraction must be as big as
possible.

Lateral filling: With bulk solids silos with lateral pneumatic filling,
mounting should not be in the filling stream as the microwave signal
will be interferred. The optimum mounting position is next to the filling.
To avoid strong pollution, the distance to the filter or dust extraction
must be as big as possible.
