Mounting location
Note
•
Correct location is key to a successful application.
•
Avoid reflective interference from vessel walls and obstructions by following the
guidelines below:
4.2.1
Nozzle design
Threaded PVDF antenna
Stainless steel horn antenna
Flanged encapsulated antenna
①
Minimum clearance: 10 mm (0.4")
②
Minimum diameter: 50 mm (2")
③
Maximum nozzle length: 500
mm (20")
● The end of the antenna must protrude a minimum of 10 mm (0.4") to avoid false echoes
being reflected from the nozzle
1)
.
● Minimum recommended nozzle diameter for the threaded PVDF antenna is 50 mm (2").
● An antenna extension (100 mm/3.93") is available for any version except the Threaded PVDF
and Flanged encapsulated antenna (FEA).
● The maximum nozzle length for the FEA is 500 mm (20").
