Antenna
Follow this step by step instruction when installing the LPG/LNG antenna.
See “LPG/LNG Antenna Requirements” on page 3-13 for information on
mounting considerations before installing the gauge on the tank.
NOTE!
There must be a mark on the pipe flange to show the direction of the
reference pins in the still pipe. Carefully check that the Closing is mounted in
the appropriate angle relative to that mark.
1. Ensure that all parts and tools are
available before carrying them to the
tank top.
2. Install the still pipe according to
mechanical installation drawing
9150072-924.
3. Check that the Cone antenna fits into
the still pipe. The gap between the
Cone antenna and the pipe must not
exceed 2 mm.
4. Mount the Pipe Cone onto the Closing
using four M6 Allen head screws. Be
careful when handling the Closing and
Pipe Cone assembly. It is important
that the Pipe Cone is undamaged.
Do not remove the yellow protective
