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.
If the instrument is mounted in the filling stream, unwanted false
measurement signals can be generated. For this reason, mount the
instrument at a position in the vessel where no disturbances, e.g. from
filling openings, agitators, etc., can occur.
This applies particularly to instrument versions with a longer probe.
