Nozzle Considerations Special considerations may have to be taken because of the nozzle,
depending on the selection of transmitter model and antenna.
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).

considerations for 5402 with
Cone Antenna.
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, please consult your local Emerson Process Management
representative for advice.
