The microprocessor sent an electronic pulse, then the transducer converts it into an acoustic pulse. The pulse travels to the level that is being measured and reflected back to the transducer. The transducer then converts its energy back into an electronic signal and stops the counter in the microprocessor. Knowing the speed of sound through the air, then it can accurately determine the distance.
