摘要
基于子波变换消噪原理,结合流量测量特定要求,提出了一种适用于涡街流量传感器信号处理的单支重构滤波方法,同时给出了滤波级数的选取方法.这种计数方法能够有效地扩大涡街流量传感器的量程下限.通过对实际信号的分析,证实了方法的有效性.
Based on wavelet denoising theory as well as the particular demand in flux measure, a single branch reconstruction algorithm aiming at vortex flowmeter signal processing is proposed in this paper. The filter level selection criterion is also discussed. The analysis based on practical signal shows that this method is useful to enlarge the lower measure limit of vortex flowmeters.
