Abstract
A system for measuring a fill level of a tank is provided. The system includes a sensor disposed in the tank and configured to generate echo data. The system further includes a computing device including a memory configured to store a plurality of historical echo lists and a processor coupled in communication with the sensor. The processor is configured to generate an echo curve based on echo data received from the sensor, generate an echo list by identifying, from the generated echo curve, a plurality of echoes, generate a plurality of echo tracks by comparing the generated echo list to the plurality of historical echo lists, identify a top level echo track from the plurality of echo tracks, the top level echo track having shifted by a threshold distance, and record a current fill level based on the identified top level echo track.
