Installation Manual
10.2 Requirements for Parabolic Antenna Gauge, RTG 2930
Please refer also to the mechanical installation drawing for more
information on the installation requirements for the Parabolic
Antenna Gauge.
See also installation drawing for requirements on service space.
10.2.1 Inclination of the Parabolic Antenna Gauge
The radar beam should be directed 1.5
°
towards the tank center.
Generally an Inclination Device must be used to ensure the correct
angle of the gauge. However, for products with high condensa-
tion, like bitumen/asphalt applications, the radar beam should be
directed vertically without any inclination towards the tank cen-
ter.
When the Inclination Device is used the plane of the cover is al-
lowed to lean a maximum of 5.5
°
away from the tank wall and a
maximum of 2.5
°
towards the tank wall. It must also be horizontal
within
±
4
°
along the tank wall. See figure 10.3.
If the plane of the cover has an inclination of 1
°
-2
°
away from the
tank wall and is horizontal within 1
°
along the wall then the Para-
bolic Antenna Gauge can be directly mounted on the cover with-
out the use of the Inclination Device. See figure 10.3.
Figure 10.3 shows the requirements on the flange for RTG 2930 with and without the Inclina-
tion Device.
