Mounting the cone antenna in a still pipe/bridle

Installation requirements for cone antenna in a still pipe/bridle
The Rosemount 5600 Series Radar Level Transmitter is suitable for measurements in still pipes and
bridles. The high signal processing capacity allows measurements even when there are several pipe
inlets, provided that the mechanical installation is done per the guidelines in this manual or related
technical note.
Figure 2-25. Example of a Bridle Mount (Left) and a Still Pipe Mount (Right)
Still pipe or bridle pipe mounting is recommended for LPG tanks and other applications where surface
conditions may be extremely turbulent. By using a pipe, foam and turbulence is reduced. Accuracy may,
however, be reduced in bridle and still pipe applications.
2.8.2
For still pipes
The 3-, 4-, and 6-in. cone antennas are designed to fit into new or existing still pipes with the
corresponding pipe size. A gap between the antenna opening and the pipe of up to 0.4 in. (10 mm) may
occur. In most applications this gap has only a limited effect on the measuring performance.
It is always recommended to have the gap as small as possible, since larger gaps cause larger
inaccuracies.
