The radar sensor should be installed at a location where
no installations cross the radar signals.
Vessel installations such as, for example, ladders, limit
switches, heating spirals, struts, etc. can cause false
echoes superimposed on the useful echo. Make sure
when planning your measuring location that the radar
signals have "free access" to the measured product.
In case of 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.

In case of agitators in the vessel, a false echo storage
should be carried out with the agitators to be in motion.
This ensures that the false reflections of the agitators are
saved in different positions.
