Mount the instrument at least 200 mm (7.874 in) away from the vessel
wall.

If you cannot keep this distance you should carry out a false echo
storage before setup. This applies mainly if buildup on the vessel wall
is expected. In this case, we recommend repeating a false echo stor-
age later with existing buildup.
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.

top
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.
