The probe should protrude into the vessel to avoid buildup. For that
reason, avoid using mounting bosses for flanges and screwed fittings.
This applies particularly to use with adhesive products.
In silos with bulk solids, material cones can form which change the
switching point. Please keep this in mind when installing the sensor
in the vessel. We recommend selecting an installation location where
the probe detects the average value of the material cone.
The probe must be mounted in a way that takes the arrangement of
the filling and emptying apertures into account.
To compensate measurement errors caused by the material cone in
cylindrical vessels, the sensor must be mounted at a distance of d/6
from the vessel wall.
