The angle of inclination depends on the vessel dimensions. It can be
easily checked with a suitable level or water leve on the sensor.
The following chart specifies the distance "a" between installation
position and vessel centre dependent on the measuring distance for
inclination angles of 2° … 10°.

Example:
In a vessel 20 m high, the installation position of the sensor is 1.4 m
from the vessel centre.
The necessary angle of inclination of 4° can be read out from this
chart.
