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.

Systems and methods for skewed basis set fitting may include obtaining measured absorption data indicative of an amount of absorption of light by a sample gas at each of multiple frequencies, determining an absorption dependent cavity time constant indicative of a skew to the measured absorption data caused by light reflections within a cavity in which the sample gas is contained, obtaining reference absorption data including basis sets indicative of reference amounts of light absorbed by each of multiple gases at each of the multiple frequencies, skewing the reference absorption data based on the absorption dependent cavity time constant to generate skewed reference absorption data, and fitting the measured absorption data to the skewed reference absorption data to identify an amount of at least one constituent gas within the sample gas.
