The Flange Ball has to be mounted on the flange prior to mounting the gauge on the tank
nozzle.
The flange needs to fulfill certain requirements in order to ensure that the radar beam is
not disturbed by the tank wall. This allows the radar signal to be reflected on the product
surface and transmitted back to the level gauge at a maximum signal strength.
The tank flange has to meet the following inclination requirements (see
) in
order to allow proper adjustment of the antenna:
•
maximum 4.5° away from the tank wall
•
maximum of 2° towards the tank wall
Figure 3-7: Maximum Inclination of Tank Flange
A. Maximum inclination towards tank center
B. Maximum inclination towards tank wall
C. 4.5° max
D. 2.0° max
In case the tank flange does not meet the requirements as illustrated in
inclination requirements for the Parabolic Antenna can still be met by using the welded
Flange Ball. The Flange Ball can be mounted at a maximum angle of 17° to the flange as
illustrated in
