Nozzle location

Beam angle
• Beam angle is the width of the cone
where the energy density is half of the
peak energy density.
• The peak energy density is directly in front
of and in line with the antenna.
• There is a signal transmitted outside the
beam angle, therefore false targets may
be detected.
Emission cone
• Keep emission cone free of interference
from ladders, pipes, I-beams or filling
streams.
• Avoid central locations on tall, narrow ves-
sels.
Environment
• Provide easy access for viewing the dis-
play and programming via the hand pro-
