摘要

本文讨论了超声波流量计中数字信号处理方法效率的研究。利用数字信号处理可以提高超声波信号的传播时间差测量的精度，这是超声波流量计的主要信息参数，并减少测量误差。得到了探测信号参数和数字信号处理相关方法参数对其在超声波流量计中应用效果影响的解析表达式。这些研究是为"流体和气体流量测量"课程开发的实验室工作准备方法学材料的一部分。

Applications of Digital Signal Processing Methods in Ultrasonic Flowmeters

The article discusses the investigation of the digital signal processing methods efficiency in ultrasonic flowmeters. Using digital signal processing allows to increase the accuracy in the propagation times difference measuring of ultrasonic signals-the main informative parameter of an ultrasonic flowmeter and to reduce the measurement error. Analytic expressions are obtained that allow one to evaluate the effect of the probing signals parameters and the digital signal processing correlation methods parameters on the effectiveness of their application in ultrasonic flowmeter. The studies were carried out as part of the preparation of methodological materials for developed laboratory work on the course “Fluid and gas flow measurement”.
