The transducer in ultrasonic level meter sends out high frequency ultrasonic pulses. When a pulse hits liquid surface, it is reflected back. The reflected ultrasonic wave is received by the transducer and converted into an electronic signal. The time interval between transmitted ultrasonic pulse and received ultrasonic pulse is directly proportional to the distance between transducer and liquid surface.
