摘要
１前言相关流量测量技术是以随机过程的相关理论为基础的一种流动参数检测技术。它在解决两相（气／液、气／固和液／固等）流体以及多相（多组份）流体的流动参数测量问题上具有巨大的潜力。相关流量测量技术的发展已有二十余年的时间了，但距工业生产中的大范围应用仍有...
Based
on correlation theory,this paper presents an intelligent cross correlation flow measurement
system by using Digital Signal Processor (DSP). Different from time domain method such as
polarity correlation, the method of frequency domain is applied to correlation calculation in this
system. Feasibility and latent advantage of this method is also discussed in this paper. This
system has master slave configuration and runs under interrupt mode. The result of experiment
shows that the system has good fuction of real time processing.
