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