If you cannot maintain this distance, you should carry out a false signal suppression during
setup. This applies particularly if buildup on the vessel wall is expected. In such cases, we rec-
ommend repeating the false signal suppression at a later date with existing buildup.
The instrument should not be mounted too close to the inflowing medium, as the radar signal
could be disrupted.
Silo with filling from top
The optimal mounting position is opposite the filling aperture. To avoid heavy soiling, the dis
-
tance to any filter or dust exhauster should be as large as possible.

Silo with lateral filling
In bulk solids silos with lateral pneumatic filling the instrument should not be mounted above the
filling stream, as the radar signal will be disrupted. The optimal mounting position is to the side
of the filling aperture. To avoid heavy soiling, the distance to any filter or dust exhauster should
be as large as possible.
