Parabolic antenna requirements
Inclination
The inclination of the Rosemount 5900C with Parabolic Antenna should not exceed 1.5 °
towards the center of the tank. For products with high condensation such as bitumen/
asphalt applications, the radar beam should be directed vertically without any inclination.
Figure 3-6: Maximum Inclination with Parabolic Antenna
A. Maximum inclination 1.5°
Flange requirements
The Rosemount 5900C with Parabolic Antenna is mounted on the tank nozzle by using the
Flange Ball. It is designed for easy adjustment of gauge inclination within the specified
limits.
There are two versions of the Flange Ball. One that is clamped to the flange by using a nut,
and another one which is welded to the flange.
