SITRANS LR250 (mA/HART) Operating Instructions, 08/2014, A5E32220602-AC 253 Appendix A: Technical reference A Note Where a number follows the parameter name [for example, Master Reset (4.1.)] this is the parameter access number via the handheld programmer. See Parameter Reference (Page 127) for a complete list of parameters. A.1 Principles of operation SITRANS LR250 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of liquids and slurries. (The microwave output level is significantly less than that emitted from cellular phones.) Radar level measurement uses the time of flight principle to determine distance to a material surface. The device transmits a signal and waits for the return echo. The transit time is directly proportional to the distance from the material. Pulse radar uses polarized electromagnetic waves. Microwave pulses are emitted from the antenna at a fixed repetition rate, and reflect off the interface between two materials with different dielectric constants (the atmosphere and the material being monitored). Electromagnetic wave propagation is virtually unaffected by temperature or pressure changes, or by changes in the vapor levels inside a vessel. Electromagnetic waves are not attenuated by dust. SITRANS LR250 consists of an enclosed electronic circuit coupled to an antenna and process connection. The electronic circuit generates a radar signal (25 GHz) that is directed to the antenna. The signal is emitted from the antenna, and the reflected echoes are digitally converted to an echo profile. The profile is analyzed to determine the distance from the material surface to the sensor reference point. See Dimension drawings (Page 209). This distance is used as a basis for the display of material level and mA output.
Appendix A: Technical reference A.2 Echo Processing SITRANS LR250 (mA/HART) 254 Operating Instructions, 08/2014, A5E32220602-AC A.2 Echo Processing A.2.1 Process Intelligence The signal processing technology embedded in Siemens radar level devices is known as Process Intelligence. Process intelligence provides high measurement reliability regardless of the dynamically changing conditions within the vessel being monitored. The embedded Process Intelligence dynamically adjusts to the constantly changing material surfaces within these vessels. Process Intelligence is able to differentiate between the true microwave reflections from the surface of the material and unwanted reflections being returned from obstructions such as seam welds or supports within a vessel. The result is repeatable, fast and reliable measurement. This technology was developed as result of field data gained over some twenty years from more than 1,000,000 installations in many industries around the world. Higher order mathematical techniques and algorithms are used to provide intelligent processing of microwave reflection profiles. This "knowledge based" technique produces superior performance and reliability.
Appendix A: Technical reference A.2 Echo Processing SITRANS LR250 (mA/HART) Operating Instructions, 08/2014, A5E32220602-AC 255 A.2.2 Echo Selection Time Varying Threshold (TVT) A Time Varying Threshold (TVT) hovers above the echo profile to screen out unwanted reflections (false echoes). In most cases the material echo is the only one which rises above the default TVT. In a vessel with obstructions, a false echo may occur. See Auto False Echo Suppression (Page 259) for more details. ① default TVT ② echo profile ③ material level ④ echo marker The device characterizes all echoes that rise above the TVT as potential good echoes. Each peak is assigned a rating based on its strength, area, height above the TVT, and reliability, amongst other characteristics. Algorithm (2.8.4.1.) The true echo is selected based on the setting for the Echo selection algorithm. Options are true First Echo, Largest Echo, or best of First and Largest.
Appendix A: Technical reference A.2 Echo Processing SITRANS LR250 (mA/HART) 256 Operating Instructions, 08/2014, A5E32220602-AC Position Detect (2.8.4.2.) The echo position detection algorithm determines which point on the echo will be used to calculate the precise time of flight, and calculates the range using the calibrated propagation velocity (see Propagation Factor (2.8.3.) for values). There are three options: ● Center ● Hybrid ● CLEF (Constrained Leading Edge Fit) Center Uses center of the echo. Hybrid Uses the Center algorithm for the top part of the vessel, and the CLEF algorithm for the part nearest the vessel bottom, according to the setting for CLEF range. CLEF (Constrained Leading Edge Fit) ● Uses the leading edge of the echo. ● Is used mainly to process the echo from materials with a low dK value. In an almost empty flat-bottomed vessel, a low dK material may reflect an echo weaker than the echo from the vessel bottom. The echo profile shows these echoes merging. The device may then report a material level equal to or lower than empty. The CLEF algorithm enables the device to report the level correctly. Example: CLEF off: Position set to Hybrid Vessel height: 1.5 m; CLEF range set to 0 (Center algorithm gives the same result.)

Appendix A: Technical reference A.2 Echo Processing SITRANS LR250 (mA/HART) 258 Operating Instructions, 08/2014, A5E32220602-AC A.2.3 CLEF Range CLEF Range (2.8.4.4.) is referenced from Low Calibration Point (process empty level ). When the Hybrid algorithm is selected in Position Detect (2.8.4.2.), the CLEF algorithm will be applied up to the limit of CLEF Range. Above this limit the Center algorithm will be applied. ① CLEF Range ② (Center algorithm applied) ③ High Calibration Point (process full level) ④ Sensor reference point ⑤ Low Calibration Point (process empty level ) A.2.4 Echo Threshold Confidence (2.8.6.1.) describes the quality of an echo. Higher values represent higher quality. Echo Threshold (2.8.4.3.) defines the minimum confidence value required for an echo to be accepted as valid and evaluated. A.2.5 Echo Lock If the echo selected by Algorithm is within the Echo Lock window, the window is centered about the echo, which is used to derive the measurement. In radar applications, two measurement verification options are used with Echo Lock (2.8.5.1.): Lock Off SITRANS LR250 responds immediately to a new selected echo (within the restrictions set by the Maximum Fill / Empty Rate), but measurement reliability is affected. Material Agitator A new measurement outside the Echo Lock Window must meet the sampling criteria before the window will move to include it. The other available options, Maximum Verification and Total Lock are not recommended for radar.
Appendix A: Technical reference A.2 Echo Processing SITRANS LR250 (mA/HART) Operating Instructions, 08/2014, A5E32220602-AC 259 A.2.6 Auto False Echo Suppression Note • For detailed instructions on using this feature via PDM see Auto False Echo Suppression (Page 92). • For detailed instructions on using this feature via the handheld programmer see Auto False Echo Suppression (2.8.7.1.). Auto False Echo Suppression is designed to learn a specific environment (for example, a particular vessel with known obstructions), and in conjunction with Auto False Echo Suppression Range to remove false echoes appearing in front of the material echo. The material level should be below all known obstructions at the moment when Auto False Echo Suppression learns the echo profile. Ideally the vessel should be empty or almost empty, and if an agitator is present, it should be running. The device learns the echo profile over the whole measurement range and the TVT is shaped around all echoes present at that moment. Auto False Echo Suppression Range (2.8.7.2.) Auto False Echo Suppression Range specifies the range within which the learned TVT is applied. Default TVT is applied over the remainder of the range. The learned TVT screens out the false echoes caused by obstructions. The default TVT allows the material echo to rise above it. Auto False Echo Suppression Range must be set to a distance shorter than the distance to the material level when the environment was learned, to avoid the material echo being screened out.

Appendix A: Technical reference A.2 Echo Processing SITRANS LR250 (mA/HART) Operating Instructions, 08/2014, A5E32220602-AC 261 A.2.7 Measurement Range Near Range (2.8.1.) Near Range programs SITRANS LR250 to ignore the zone in front of the antenna. The default blanking distance is 50 mm (1.97") from the end of the antenna. Near Range allows you to increase the blanking value from its factory default. But Auto False Echo Suppression (2.8.7.1.) is generally recommended in preference to extending the blanking distance from factory values. Far Range (2.8.2.) Far Range can be used in applications where the base of the vessel is conical or parabolic. A reliable echo may be available below the vessel empty distance, due to an indirect reflection path. Increasing Far Range to 30% or 40% can provide stable empty vessel readings. A.2.8 Measurement Response Note Units are defined in Units (2.2.1.) and are in meters by default. Response Rate (2.4.1.) limits the maximum rate at which the display and output respond to changes in the measurement. There are three preset options: slow, medium, and fast. Once the real process fill/empty rate (m/s by default) is established, a response rate can be selected that is slightly higher than the application rate. Response Rate automatically adjusts the filters that affect the output response rate. Response Rate (2.4.1.) Fill Rate per Minute (2.4.2.)/Empty Rate per Minute (2.4.3.) Damping Filter (2.2.4.) * Slow 0.1 m/min (0.32 ft/min) 10 s Medium 1.0 m/min (3.28 ft.min) 10 s Fast 10.0 m/min (32.8 ft/min) 0 s
Appendix A: Technical reference A.3 Analog Output SITRANS LR250 (mA/HART) 262 Operating Instructions, 08/2014, A5E32220602-AC A.2.9 Damping Damping Filter (2.2.4.) smooths out the response to a sudden change in level. This is an exponential filter and the engineering unit is always in seconds. In 5 time constants the output rises exponentially: from 63.2% of the change in the first time constant, to almost 100% of the change by the end of the 5th time constant. Damping example time constant = 2 seconds input (level) change = 2 m A.3 Analog Output The mA Output (current output) is proportional to material level in the range 4 to 20 mA. 0% and 100% are percentages of the full-scale reading (m, cm, mm, ft, in). Typically mA output is set so that 4 mA equals 0% and 20 mA equals 100%. When SITRANS LR250 is put into PROGRAM mode (for example, by navigating through the menu) it stops updating the output of the device (local user interface and mA Output). It stores the most recent measurement, and holds the associated readings and mA signal output. The device reverts to the parameter last addressed during the previous program session. When the device is returned to Measurement mode, the transceiver resumes operation. The reading and mA output default to the last measurement taken. The reading and associated outputs migrate to the current process level at a rate controlled by Response Rate (2.4.1.). If the device is left in PROGRAM mode for 10 minutes without input, it automatically reverts to Measurement mode.
Appendix A: Technical reference A.3 Analog Output SITRANS LR250 (mA/HART) Operating Instructions, 08/2014, A5E32220602-AC 263 A.3.1 Sensor Mode This parameter controls the input. Depending on the reference point used, the measurement reports either Level, Space, or Distance. By default Sensor Mode is set to Level. Operation Description Reference point NO SERVICE Measurement and associated loop current not being updated. Device defaults to Fail-safe mode a). LEVEL Distance to material surface Low Calibration Point (process empty level) SPACE Distance to material surface High Calibration Point (process full level) DISTANCE Distance to material surface Sensor reference point a) See Fail-safe Mode (Page 265). You also have the option to put the device out of service, in which case the device defaults to Fail-safe mode, and the reported level depends on the device type. A standard device reports the last valid reading, and a NAMUR NE 43-compliant device reports the user-defined value for Material Level (3.58 mA by default). ① Sensor reference point ⑤ 4 mA 0% ② High calibration point ⑥ Distance ③ 20 mA 100% ⑦ Level ④ Space ⑧ Low calibration point
Appendix A: Technical reference A.3 Analog Output SITRANS LR250 (mA/HART) 264 Operating Instructions, 08/2014, A5E32220602-AC A.3.2 Current Output Function Current Output Function (2.6.1.) controls the mA output and applies any relevant scaling. By default it is set to Level. Other options are Space, Distance, and Volume. (The device can carry out a volume calculation only after a vessel shape has been specified.) When a volume application type is chosen, Sensor Mode remains as Level and the mA Output is automatically converted to Volume. To view the mA reading in the secondary region of the LCD, press on the handheld programmer. A.3.3 Loss of Echo (LOE) A loss of echo (LOE) occurs when the calculated measurement is judged to be unreliable because the echo confidence value has dropped below the echo confidence threshold. Confidence (2.8.6.1.) describes the quality of an echo. Higher values represent higher quality. Echo Threshold (2.8.4.3.) defines the minimum confidence value required for an echo to be accepted as valid and evaluated. If the LOE condition persists beyond the time limit set in LOE Timer (2.5.2.) the LCD displays the Service Required icon, and the text region displays the fault code S: 0 and the text LOE. If two faults are present at the same time, the fault code, error text, and error icon for each fault are displayed alternately. For example, Loss of Echo and Fail-safe.
Appendix A: Technical reference A.4 Maximum Process Temperature Chart SITRANS LR250 (mA/HART) Operating Instructions, 08/2014, A5E32220602-AC 265 A.3.4 Fail-safe Mode The purpose of the Fail-safe setting is to put the process into a safe mode of operation in the event of a fault or failure. The value to be reported in the event of a fault is selected so that a loss of power or loss of signal triggers the same response as an unsafe level. LOE Timer (2.5.2.) determines the length of time a Loss of Echo (LOE) condition will persist before a Fail-safe state is activated. The default setting is 100 seconds.
