2,Introduction

3,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).
