Introduction
The Ultrasonic sensor uses sound waves to do non-contact and wear-free detection on target subjects. It can be used to detect either transparent or colored objects, metal objects or non-metallic objects, as well as solid, liquid or powdered substance. Ambient conditions such as environmental smoke, dust, environment or rain have very small affect on the detection performance of ultrasonic sensors.
Principle
Transmitting ultrasonic transducer emits ultrasonic pulses propagated to the measured media through communication media, through reflection and then return to the receiving transducer through the acoustic medium, the measured ultrasonic pulse propagates from the transmitter to the receiver in the acoustic medium of time. Then according to the speed of sound in the acoustic medium, it can be considered from the transducer to the media surface distance. To determine the liquid level. Therefore, we can calculate the distance from the probe to the reflecting surface D = C * t / 2 (divided by 2 is because the sound waves from the transmitter to the receiver is actually a round, D is the distance, C is the speed of sound, t is the time).
