Solid-state electronics measure the time it takes from transmitted sound to return of the echo. With reference to the speed of sound in air, the exact distance of the liquid surface from the sensor can be calculated with high accuracy (±0.2% of maximum range). Level/Distance measurements are automatically temperature-compensated throughout the operating temperature range of the sensor.
