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

In vessels with conical bottom it can be advantageous to mount the
sensor in the center of the vessel, as measurement is then possible
down to the lowest point of the vessel bottom.
