WebNov 8, 2024 · Ultrasonic level sensors work by the “time of flight” principle using the speed of sound. The sensor sends pulses toward the surface and receives echoes pulses back. Basically, the transmitter divides the time between the pulse and its echo by two, and that is the distance to the surface of the material. Do ultrasonic sensors make noise? WebA HyperSonic Sound system – or HSS – does not use physical speakers. HSS pulsates quartz crystals at a frequency thousands of times faster than the vibrations in a normal speaker – creating ultrasonic waves at frequencies far beyond human hearing. Unlike lower-frequency sound, these waves travel in a tight path – a beam.
