Vessel fittings
The installation position of the radar sensor should be selected such that no fittings cross the microwave
signals.
Vessel fittings such as ladders, limit switches, heating coils, vessel bracing, etc. can cause interference echoes
and adversely affect the useful echo. When planning your measuring point you should ensure that the radar
signals have as "clear a view" as possible of the solids.
If there are fittings in the vessel, you should save the interference signal during the commissioning procedure.
If large vessel fittings such as bracing and supports cause interference echoes these can be damped by
additional measures. Small sheet metal covers installed at angles over the fittings will "scatter" the radar
signals and thus effectively prevent direct interference echo reflection.
Mixer units
If there is a mixer unit in the vessel, you should complete a false signal suppression process whilst the mixer
unit is operating. This will ensure that the interference reflections from the mixer unit are saved in various
positions.
