Application Examples
The application examples used in this manual illustrate typical installations using
SITRANS LR200 (see
Appendix E: Application Examples on page 115). Because there is
often a range of ways to approach an application, other configurations may also apply.
In all examples, substitute your own application details. If the examples do not apply to
your application, check the applicable parameter reference for the available options.

SITRANS LR200
SITRANS LR200: Overview
SITRANS LR200 is a 2-wire, 6 GHz pulse radar level transmitter for continuous monitoring
of liquids and slurries in storage and process vessels including high temperature and
pressure, to a range of 20 m (66 ft).
The instrument consists of an electronic circuit coupled to the antenna and process
connection.
SITRANS LR200 supports PROFIBUS PA communications protocol and SIMATIC PDM
software. Signals are processed using Process Intelligence which has been field-proven
in over 1,000,000 applications worldwide (ultrasonic and radar). This device supports
acyclic communications from both a PROFIBUS Class I and Class II master.
Applications
Programming
SITRANS LR200 is very easy to install and configure via a graphical user interface (LUI).
You can modify the built-in parameters either locally via the Siemens infrared handheld
programmer, or from a remote location using SIMATIC PDM.
Approvals
SITRANS LR200 is available in three versions:
• General Purpose (non-hazardous)
• Intrinsically Safe (with suitable barrier)
•Non-Incendive
See
Approvals on page 9 for details.
Process Connections
A wide range of process connections and antenna options is available to suit virtually
any vessel configuration.
shield length: 100 mm (4"):
use for nozzles of 100 mm (4")
or less in length
shield length 250 mm (10"):

Installation
Installation
1)
WARNINGS:
• Handle the device using the enclosure, not the antenna, to avoid
damage.
• Installation shall only be performed by qualified personnel and in
accordance with local governing regulations.
• SITRANS LR200 is to be used only in the manner outlined in this
manual, otherwise protection provided by the device may be impaired.
• Never attempt to loosen, remove, or disassemble process connection
or instrument housing while vessel contents are under pressure.
• This product is designated as a Pressure Accessory per Directive
97/23/EC and is not intended for use as a safety device.
• 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.
• 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:
• Refer to the device nameplate for approval information.
• The Process Device Tag shall remain with the process pressure boundary
assembly1). In the event the instrument 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.
• The serial numbers stamped in each process connection body provide a unique
identification number indicating date of manufacture.
Example: MMDDYY – XXX (where MM = month, DD = day, YY = year, and
XXX = sequential unit produced)
Further markings (space permitting) indicate flange configuration, size, pressure
class, material, and material heat code.
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.

Installation
Mounting location
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.1)
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.
Nozzle location
Notes:
• Correct location is key to a successful application.
• Avoid reflective interference from vessel walls and obstructions by following the
guidelines below
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, see
Appendix H: Flange Adapter Versions on
page 142.
1) When the locking ring is secured, it prevents the enclosure rotating on the threaded connection.
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 SITRANS LR200 at
the centre of a flat-topped tank: please discuss this with your Siemens Milltronics
Representative.
