Abstract
Ultrasonic flow sensor is increasingly widely used in fluid control system, and its measurement accuracy and stability are crucial to industrial automation, energy and management. Aiming at the limitations of traditional flow measurement method, this paper proposes an optimization scheme of ultrasonic flow sensing system based on jet difference method, aiming to improve the measurement accuracy and reduce the interference of environmental factors. Through the comprehensive study of the sensor structure design, signal processing algorithm and temperature compensation mechanism, a complete mathematical model is established, and the finite element analysis method is used to verify the performance of the sensor under different working conditions. The experimental results show that the optimization scheme can effectively reduce the measurement error, and the measurement accuracy reaches ± 0.5% in the range of 0.5-10 m/s, which is more than 30% higher than the traditional method. In addition, by introducing the adaptive filtering algorithm, the anti-interference ability of the system is significantly improved, and the stable operation under complex working conditions is ensured.
