Installation
Mounting location
Nozzle design
The end of the horn must protrude
a minimum of 10 mm (0.4”) to avoid
false echoes being reflected from
the nozzle.
Optional antenna extensions:
100 mm (3.93"), 200 mm (70.9"),
500 mm (19.69"), 1000 mm (39.4")

Nozzle location
Keep emission cone free of
interference from ladders,
pipes, I-beams or filling
streams.
Avoid central locations on
tall, narrow vessels.
Align the antenna so that the
radar cone is perpendicular
to the surface of the
monitored material, if
possible. (See
Easy Aimer
on page 16.)
Notes:
Correct location is key to a successful application.
Avoid reflective interference from vessel walls and obstructions by following the
guidelines below.
1)
Extensions are not recommended for applications where there may be excessive
visible vibration. Please consult factory for more information.
Notes:
Beam angle depends on horn size:
see below.
For details on avoiding false
echoes, see
Auto False Echo
Suppression
