3.3.5 Non-metallic tanks
The walls in non-metallic tanks can be invisible to the radar signal, so nearby objects
outside the tank may cause disturbing radar echoes. Wherever possible, the transmitter
should be positioned so that objects close to the tank are kept outside the signal beam.
3.3.6 Beam width and beam angle
The transmitter should be mounted with as few internal structures as possible within the
signal beam. Refer to
distances.
