Application for Ultrasonic Level Sensors:
Ultrasonic level sensors work by the "time of flight" principle using the speed of sound. The sensor emits a high-frequency pulse, generally in the 20 kHz to 200 kHz range, and then listens for the echo. The pulse is transmitted in a cone, usually about 6° at the apex. The pulse impacts the level surface and is reflected back to the sensor, now acting as a receiver , and then to the transmitter for signal processing.
