4.4 Mounting instructions
Radar sensors for level measurement emit electromagnetic waves.
The polarization is the direction of the electrical component of these
waves.
The polarization direction is marked by a nose on the housing, see
following drawing:

1 Nose for marking the direction of polarisation
Information:
When the housing is rotated, the direction of polarization changes
and hence the influence of the false echo on the measured value.
Please keep this in mind when mounting or making changes later.
Mount the instrument at least 200 mm (7.874 in) away from the vessel
wall.
