Rosemount Raptor
Section 5. Installing a Raptor Level Gauging System
The following antenna types are available:
5900S with Horn Antenna
•Horn
5900S with Parabolic Antenna
• Parabolic
5900S with Still-pipe Array Antenna
• Still-Pipe Array Fixed
• Still-Pipe Array Hatch
5900S with LPG Antenna
Depending on the pressure rating of the flange, choose one of the following
options:
• LPG/LNG 150 PSI + Valve
• LPG/LNG 150 PSI
• LPG/LNG 300 PSI + Valve
• LPG/LNG 300 PSI
• LPG/LNG 600 PSI + Valve
• LPG/LNG 600
For Still-pipe Array antennas you need to specify Antenna Size and Pipe
Diameter. The Pipe Diameter is used to compensate for the lower microwave
propagation speed inside a still-pipe. See also “Using the Calibrate Function”
on page 5-123 for information on how to calibrate the 5900S for still-pipe
installations.
To configure a User Defined antenna (advanced)
The User Defined option (User Def. Free Propagation, User Def. Linear Pipe,
and User Def. Modeconv. Pipe) should only be used in special situations for
non-standard antennas:
a. Choose the appropriate antenna type:
- User Defined Free Propagation
- User Defined Pipe
- User Defined Pipe Array
b. Enter the Tank Connection Length in the TCL input field.
c. For still pipe applications, type the inner diameter of the still pipe in
the Pipe Diameter input field.
d. In case there are disturbances close to the nozzle you may need to
adjust the Hold Off Distance. By increasing the Hold Off distance,
the measurement range is reduced in the upper part of the tank.
9. In the 5900S RLG Properties/Antenna window click the Apply button to
save the configuration.
See Rosemount 5900S Reference Manual (Document No. 300520EN)
for more information on Hold Off Distance and other level gauge
parameters.
