Beam angle
• Beam angle is the width of the cone
where the energy density is half of
the peak energy density
• Peak energy density is directly in
front of and in line with the antenna.
• Signal is 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 vessels.
• LR560 uses circular polarization.
Rotation of device is not required to
optimize signal.
Environment
• Provide easy access for
viewing the display and
programming via the
handheld programmer.
• Provide an environment
suitable to the ambient
temperature rating.
• Use a sunshield if the
instrument will be
mounted in direct
sunlight.
Notes:
• Correct location is key to a successful application.
• Avoid reflective interference from vessel walls and obstructions by following the
guidelines below.
Notes:
• For details on avoiding false echoes, see
Auto False Echo Suppression (2.4.8.1.) on
page 142.
