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.

In vessels with conical bottom it can be advantageous to mount the
device in the centre of the vessel, as measurement is then possible
down to the bottom.

The sealing surface at the bottom of the hexagon is the beginning of
the measuring range and at the same time the reference plane for the
min./max. adjustment, see the following graphic:

For nozzle mounting, the nozzle should be as short as possible and
its end rounded. This reduces false reflections from the nozzle.
The antenna edge should protrude at least 5 mm (0.2 in) out of the
nozzle.
