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 vessels.
• LR560 uses circular polarization. Rotation of device is not required to optimize
signal.
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
Shaper Mode (2.8.4.)
on page 126.
