3.3.3 Mounting in pipes
Still-pipe mounting is recommended for tanks with extremely turbulent surface conditions. All cone
antenna sizes for the Rosemount 5400 can be used for still-pipe installations. The 3-in. (75 mm) antenna
for the Rosemount 5401 is designed for use in still-pipes only. Parabolic and rod antennas are not
recommended for still-pipes.
When the transmitter is mounted on a still-pipe, the inclination should be within 1°. The gap between
the antenna and the still-pipe may be up to 0.2 in. (5 mm).
