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.
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).
Figure 3-9. Nozzle 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.
