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 may 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.
