Page 233 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.
Page 234 Appendix A: Technical reference A.2 Echo processing 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.
Page 235 Appendix A: Technical reference A.2 Echo processing 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 (2.5.7.1.) The true echo is selected based on the setting for the Echo selection algorithm.

Page 239 Appendix A: Technical reference A.2 Echo processing 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. Example before Auto False Echo Suppression ①...
Page 240 Appendix A: Technical reference A.2 Echo processing A.2.8 Measurement Range Near Range (2.5.1.) 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.
Page 241 Appendix A: Technical reference A.3 Maximum Process Temperature Chart 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 faulty power supply: Upon receiving a reliable echo, the loss of echo condition is aborted, the Service Required icon and error message are cleared, and the reading returns to the current level.
