In a cylindrical silo with conical outlet, the mounting is carried out on
a third up to the half of the vessel radius from outside (see following
drawing).

Fig. 17: Mounting position and orientation
Direct the sensor in such a way that the radar signal reaches the
lowest vessel level. Hence it is possible to detect the complete vessel
volume.
Tip:
The easiest way to align the sensor is with the optional swivelling
holder. Determine the suitable inclination angle and check the align-
ment with the alignment aid in the VEGA Tools app on the sensor.
Alternatively, the angle of inclination can be determined using the
following drawing and table. It depends on the measuring distance "d"
and the distance "a" between vessel centre and mounting position.
Check the alignment with a suitable level or water level.
