The radar sensor should be installed at a location where no
installations cross the microwave signals.
Vessel installations such as, for example, ladders, limit
switches, heating spirals, struts, etc. can cause false echoes
that get superimposed on the useful echo. Make sure when
planning your measuring site that the radar sensor has a "clear
view" to the measured product.
If there are existing vessel installations, a false echo storage
should be carried out during setup.
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 scatter the radar signals and avoid a direct false
echo reflection.

If there are agitators in the vessel, a false echo storage 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.
