Metal orifice plates, installed at an angle to scatter the radar signals, help prevent interference
echoes
Measurement in a plastic vessel
If the outer wall of the vessel is made of a non-conductive material (e.g. GFRP) microwaves can also
be reflected off interfering installations outside of the vessel (e.g. metallic pipes (1), ladders (2),
grates (3) etc.). Therefore there should be no such interfering installations in the signal beam.
