Mounting Guidelines

Nozzle fabrication
Weld seams must be on the outside of the nozzle. Seams or lips on the inside of the
nozzle may cause erratic readings.
Nozzle design
• The nozzle should be as short as possible.
• If your application requires a nozzle longer than our
recommended maximum length consider using a
shielded rod.
Horn Antennas
The end of the horn should protrude a minimum of 10
mm (0.4") to avoid interference from the nozzle.
Threaded Rod Antenna
WARNING: For pressure applications, it is necessary to use PTFE tape
or other appropriate thread sealing compound, and to tighten the
process connection beyond hand-tight.
1.5" or 2" threaded
process connections
are available in three
thread types:
NPT, BSP , and G.
