Ultrasonic uses the sound waves, and Radar uses radio waves. Ultrasonics, typically refers to piezoelectric transducers or capacitive transducers. Ultrasonic level transmitter has no moving parts, and it can measure level without making physical contact with the object. Systems typically use a transducer which generates sound waves in the ultrasonic range, above 18 kHz, by turning electrical energy into sound, then upon receiving the echo turn the sound waves into electrical energy which can be measured and displayed. Ultrasound can be used for measuring wind speed and direction (anemometer), tank or channel fluid level, and speed through air or water. This technique is known as Sonomicrometry where the transit-time of the ultrasound signal is measured electronically (ie digitally) and converted mathematically to the distance between transducers assuming the speed of sound of the medium between the transducers is known. The chip operates by transmitting a burst of oscillations with a transducer, then using the same transducer to listen for a return echo.
