Working on the principals of detecting sound to provide regular and accurate measurements for liquids is the basic functioning of ultrasonic liquid sensors.

They emit a high-frequency pulse of ultrasonic sound which is bounced back with a specific accuracy and hence, the final detection of the pulse tells the level of liquids in the tanks or cylinders. Basically, the time it takes to come back helps these Liquid Level Indicators to identify the levels of liquids. This time is calculated by the speed with which it returns back to the device whereas the principal these ultrasonic devices works upon is basically similar to echolocation used by dolphins and bats.
