Note:
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.
The centre of the antenna lens is the beginning of the measuring
range and at the same time the reference plane for the min./max.

When mounting the device, keep a distance of at least 200 mm
(7.874 in) from the vessel wall. If the device is installed in the center
of dished or round vessel tops, multiple echoes can arise. However,
these can be suppressed by an appropriate adjustment (see chapter
" Set up").
If you cannot maintain this distance, you should carry out a false
signal suppression during setup. This applies particularly if buildup
on the vessel wall is expected. In such cases, we recommend
repeating the false signal suppression at a later date with existing
buildup.
