Ultrasonic pulses are emitted by the transducer to the surface of measured medium, reflected there, partly received by the transducer and converted into electronic signal. The pulses travel at the speed of sound - the elapsed time from emission to reception of the signals is directly proportional to the distance from transducer to the medium surface. The relationship among distance S, sound speed C and transmission time T is: S=C×T/2
