Orientation
To measure as much of the vessel volume as possible, the sensor
should be aligned so that the measuring beam reaches the lowest
level in the vessel. In a cylindrical silo with conical outlet mounting is
carried out on a socket. It should be positioned on one third up to the
half of the vessel radius.

If mounting in the centre of the silo is not possible, the sensor can be
directed to the vessel center by using the optional swivelling holder.
The following description shows a simple way to determine the
required angle of inclination.
