these can be suppressed by an appropriate adjustment (see chapter
" Setup").
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 measuring range of VEGAPULS 64 begins physically at the end
of the antenna. The min./max. adjustment, however, begins at the
