10.2.2 Free Space Requirements
The radar beam of the Parabolic Antenna Gauge is 10° wide. Obstacles
(construction bars, pipes larger than Ø 2", etc.) within the radar beam are
generally not accepted, as these can result in disturbing echoes.
However, in most cases, a smooth tank wall or heating coils will not have
any significant influence on the radar beam. For evaluation contact
