If you cannot keep this distance you should carry out a false echo sto-
rage before setup. This applies mainly if buildup on the vessel wall is
expected. In this case, we recommend repeating a false echo storage
later with existing buildup.
Mounting should not be too close to the inflowing 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.
Fig. 9: Mounting of the radar sensor with inflowing medium
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.
