Preliminary
This instruction covers installation of the Rosemount 5900 Still-pipe Array
antenna available for pipe size 5, 6, 8, 10 and 12 inch.
The Rosemount 5900 is designed for still-pipe mounting and can be mounted
on existing still-pipe flanges without taking the tank out of operation.
There are two versions available in order to suit various requirements for easy
installation and maintenance:
• The Rosemount 5900 Still-pipe Array antenna Fixed version.
This version has a flange for easy mounting when there is no need for
opening the still-pipe for hand dipping.
• The Rosemount 5900 Still-pipe Array antenna Hinged Hatch version.
This version is suitable when the still-pipe needs to be opened for hand
dipping.
Still Pipe Requirements
The Rosemount 5900 Still-pipe Array antenna fits 5", 6", 8", 10" and 12"
flanges and pipes. The adaption is accomplished by selecting a suitable
Still-pipe Array antenna. The gauge has a flange to seal the tank.
The still pipe must be vertical within 0.5° (0.2 m over 20 m).
Table 3-3 shows the wide range of schedules and pipe inner diameters that
the Array antennas can be mounted in.
