VEGA VEGAVIB 61 - transistor (NPN-PNP) - Manual (Page 12)

In silos for bulk solids, material cones can form and change the
switching point. Please keep this in mind when installing the sensor in
the vessel. We recommend selecting an installation location where the
vibrating rod detects an average value of the material cone.
The vibrating rod 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.
