If large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.
Small, inclined sheet metal baffles above the installations "

the radar signals and prevent direct interfering reflections.

In liquids, direct the device as perpendicular as possible to the me-
dium surface to achieve optimum measurement results.

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.

Through the action of filling, stirring and other processes in the vessel,
compact foams which considerably damp the emitted signals may
form on the medium surface.
