Pressure Application
Pressure Equipment Directive, PED, 97/23/EC
Siemens Level Transmitters with flanged, threaded, or sanitary clamp type process mounts
have no pressure-bearing housing of their own and, therefore, do not come under the Pressure
Equipment Directive as pressure or safety accessories, (see EU Commission Guideline 1/8).
Installation3)
1) See
Non-Sparking/Energy Limited wiring on page 10.
2) See
Non-incendive wiring (US only) on page 10.
WARNINGS:
• Never attempt to loosen, remove, or disassemble process connection or instru-
ment housing while vessel contents are under pressure.
• Improper installation may result in loss of process pressure.
WARNINGS:
• Installation shall only be performed by qualified personnel and in accor-
dance 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.
• Handle the device using the enclosure, not the antenna or the device tag, to
avoid damage.
Notes:
• The Process Device Tag shall remain with the process pressure boundary assembly3). In
the event the device package is replaced, the Process Device Tag shall be transferred to
the replacement unit.
• SITRANS LR200 units are hydrostatically tested, meeting or exceeding the requirements
of the ASME Boiler and Pressure Vessel Code and the European Pressure Equipment
Directive.
3) 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 emit-
ter, but normally excluding the electrical enclosure.

Nozzle design
• The end of the shield section should protrude a minimum
of 10 mm (0.4”) to avoid false echoes being reflected from
the nozzle.
Nozzle location
Environment
• Provide an environment suitable to the housing rating and materials of construction.
• Provide a sunshield if the device will be mounted in direct sunlight.
Access for programming
• Provide easy access for viewing the display and programming via the hand programmer.
Location on a manhole cover
• A manhole cover is typically a covered nozzle with a
diameter 610 mm (24”) or greater.
• For optimum signal conditions, locate the antenna
off-center, typically 100 mm (4") from the side.
(continued on next page)
Notes:
• For nozzles 100 mm (4") in length or shorter use the 100 mm (4") shield.
• For nozzles 250 mm (10") in length or shorter use the 250 mm (10") shield.
• For details on other applications, please see the full manual which can be downloaded
from www.siemens.com/LR200.
WARNING: For vessels with conical or parabolic tops, avoid mounting the
instrument at the centre. (The concavity of the top can focus echoes into the centre,
giving false readings.)
Note: Under certain circumstances, it may be acceptable to mount the device at the centre of
a flat-topped tank. Please discuss this with your local Siemens representative.

Nozzle location (continued)
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.
• Locate the antenna away from the side
wall, to avoid interference from indirect
echoes.
• Make allowance for the emission cone spreading.
Mounting instructions
Threaded Version
1) Before inserting the device into its mounting connection,
check to ensure the threads are matching to avoid dam-
aging them.
2) Screw the device into the process connection, and hand
tighten.
3) To rotate the enclosure, first loosen the three set-screws
securing the locking ring. After positioning the enclosure,
retighten the screws.
Flanged Version
WARNING: For pressure applications, use PTFE tape or other appropriate thread
sealing compound, and tighten the process connection beyond hand-tight (max.
torque 40 N·m (30 ft.lbs).
Notes:
• There is no limit to the number of times the device can be rotated without damage.
• Orient the front or back of the device towards the closest vessel wall.
• Do not rotate the enclosure after programming and device configuration (a polarity shift
of the transmit pulse may cause an error).
WARNING: 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.
