If large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.
Small, inclined sheet metal or plastic baffles above the installations
scatter the ultrasonic signals and avoid direct false echoes.

If there are agitators in the vessel, a false signal suppression should
be carried out with the agitators in motion. This ensures that the
interfering reflections from the agitators are saved with the blades in
different positions.

Do not mount the instruments in or above the filling stream. Make sure
that you detect the medium surface, not the inflowing product.
