Abstract
ABSTRACTIn aviation, petroleum and chemical industries and other special areas of production, since the liquid in containers mostly are flammable, explosive, volatile, and corrosive mixtures, the accurate measurement of the liquid level is essential to the real‐time control and production process. In this study, an approximation algorithm based on echo pressure model for measuring the liquid level in special field is proposed in this paper. According to the model, a complete lateral incident ultrasonic measurement system is constructed for the inductive liquid level detection technology in special applications, an algorithm model of the echo pressure is established, which provides the determination of the liquid level relying on the characteristic curve of the echo pressure. The model in this study converts complex interaction problems of sound fields into the echo pressure calculation, which quickly determines performance parameters of sound fields, and a virtual reflection method is used to calculate the sound pressure of the receiving transducer in different states, which reduces computational complexity, finally, through the simulation and experiment, the algorithm is validated. The results are consistent with expectations, and the algorithm can be further applied in practice.
