is not intended for use as a safety device.
• Do not attempt to loosen, remove, or disassemble process connection or
instrument housing while vessel contents are under pressure.
• Improper installation may result in loss of process pressure.
1. The process pressure boundary assembly comprises the components that act as a barrier against
pressure loss from the process vessel: that is, the combination of process connection body and
emitter, but normally excluding the electrical enclosure.
WARNINGS:
• Installation shall only be performed by qualified personnel and in
accordance with local governing regulations.
• Materials of construction are chosen based on their chemical compatibility (or
inertness) for general purposes. For exposure to specific environments, check
with chemical compatibility charts before installing.
Notes:
• For European Union and member countries, installation must be according to ETSI EN
302372.
• The Process Device Tag shall remain with the process pressure boundary assembly1. In
the event the device package is replaced, the Process Device Tag shall be transferred to
the replacement unit.

• Provide an environment suitable to the housing rating and materials of construction.
• Provide a sunshield if the device will be mounted in direct sunlight.
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")1
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.
Mounting instructions
1. Extensions are not recommended for applications where there may be excessive visible vibration. Please consult
factory for more information.
