3.3.5 Nozzle considerations
Special considerations may have to be taken because of the nozzle, depending on the selection of
transmitter model and antenna.
Rosemount 5402 with cone antenna
The antenna can be recessed in smooth nozzles up to 6 ft (2 m). If the inside of the nozzle contains
disturbing objects, use the extended cone (I).

Rosemount 5402 with process seal antenna
The antenna can be used on nozzles up to 6 ft (2 m), (J). Disturbing objects inside the nozzle (K) may
impact the measurement, and should therefore be avoided.
The flange on the tank should have a flat or raised face. Other tank flanges may be possible, contact your
local Emerson Automation Solutions representative for advice.
