dance with local governing regulations.
• Never attempt to loosen, remove, or disassemble process connection or
instrument housing while vessel contents are under pressure.
• The user is responsible for the selection of bolting and gasket materials
which will fall within the limits of the flange and its intended use and which
are suitable for the service conditions.
• Improper installation may result in loss of process pressure.
Notes:

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.
