Follow this instruction when installing the Rosemount 5900 with Horn
Antenna. See “Horn Antenna Requirements” on page 3-4 for information on
mounting considerations before installing the gauge on the tank.
NOTE!
When determining conduit dimensions (if used), note that the Horn Antenna
Gauge may be inclined 4° towards the center of the tank (see Figure 3-2 on

1. Check that all parts and tools are
available before carrying them up to
the tank roof.
2. Put a gasket on the socket and
carefully insert the horn antenna and
flange assembly.
3. Tighten the flange onto the socket by
using suitable screws and nuts
(customer supplied).
4. Put the adapter on the flange.
Tighten the four M10 screws with
