3 Description 3.1 SITRANS LR250 overview WARNING SITRANS LR250 is to be used only in the manner outlined in this manual, otherwise protection provided by the device may be impaired. SITRANS LR250 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of liquids and slurries in storage vessels including high pressure and high temperature, to a range of 20 meters (66 feet). It is ideal for small vessels and low dielectric media.
Description 3.2 Programming 3.2 Programming This device is very easy to install and configure via a graphical local user interface (LUI). You can modify the built in parameters either locally via the Siemens infrared handheld programmer, or from a remote location using one of the following options: ● SIMATIC PDM ● FDT/DTM platform (such as PACTware™ or FieldCare) 3.3 Applications ● liquids and slurries ● bulk storage vessels ● simple process vessels 3.
Installing/mounting 4 WARNING • Installation shall only be performed by qualified personnel and in accordance with local governing regulations. • Handle the device using the enclosure, not the process connection tag, to avoid damage. • Take special care when handling the threaded PVDF and Flanged encapsulated antennas. Any damage to the antenna surface, particularly to the tip/lens, could affect performance.
Installing/mounting 4.1 Pressure applications 4.1 Pressure applications WARNING Pressure applications • Never attempt to loosen, remove, or disassemble process connection or device housing while vessel contents are under pressure. • The user is responsible for the selection of bolting and gasket (except for Flanged encapsulated antenna) materials which will fall within the limits of the process connection and its intended use and which are suitable for the service conditions.
Installing/mounting 4.2 Mounting location 4.2.1 Nozzle design Threaded PVDF antenna Stainless steel horn antenna Flanged encapsulated antenna ① Minimum clearance: 10 mm (0.4") ② Minimum diameter: 50 mm (2") ③ Maximum nozzle length: 500 mm (20") ● The end of the antenna must protrude a minimum of 10 mm (0.4") to avoid false echoes being reflected from the nozzle1). ● Minimum recommended nozzle diameter for the threaded PVDF antenna is 50 mm (2"). ● An antenna extension (100 mm/3.
Installing/mounting 4.2 Mounting 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.
Installing/mounting 4.2 Mounting location Beam angle Note • Beam width depends on antenna size: see below. • For details on avoiding false echoes, see Auto False Echo Suppression (Page 207). ● 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.
Installing/mounting 4.2 Mounting location 4.2.3 Orientation in a vessel with obstructions Polarization reference point For best results on a vessel with obstructions, or a stillpipe with openings, orient the front or back of the device toward the obstructions. For an illustration, see Device orientation (Page 21). ① ② ③ 4.2.
Installing/mounting 4.2 Mounting location 4.2.5 Stillpipe or Bypass Pipe requirements ● The pipe diameter must be matched with the antenna size. Use the largest antenna size that will fit the stillpipe/bypass pipe1). See Threaded Horn dimensions (Page 177) or Raised-Face Flange per EN 1092-1 (Page 194). ● One continuous length of metallic pipe is preferred, without joints. Bad joints create reflections. ● Joints (if unavoidable) must be machined to ± 0.25 mm (± 0.
Installing/mounting 4.3 Installation instructions 4.3 Installation instructions WARNING For pressure applications, it will be necessary to use PTFE tape or other appropriate thread sealing compound, and to tighten the process connection beyond hand-tight. (The maximum recommended torque for Threaded versions is 40 N-m (30 ft.lbs.) See Flange bolting, Flanged encapsulated antenna only (Page 22) for FEA recommended torque values.
Installing/mounting 4.4 Flange bolting, Flanged encapsulated antenna only Flange bolting: recommended torque Pressure class ASME B16.
Installing/mounting 4.4 Flange bolting, Flanged encapsulated antenna only Recommendations for flange bolting: ● Use cross-pattern sequence as shown ● Check uniformity of the flange gap ● Apply adjustments by selective tightening if required ● Torque incrementally until desired value is reached ● Check/re-torque after 4 to 6 hours ● Check bolts periodically, re-torque as required ● Use new lens, O-ring and spring washers after removal from installation.
