摘要
介绍了测量两相流流速的方法 ,该方法可以提高系统的抗干扰能力、稳定性和性价比 ;讨论了该方法的工作原理 ,并建立了一套模拟实际测量情况的测量系统。试验结果证明 ,基于差动自相关原理的测量方法是完全可行的。
An auto-correlation measurement method that can be used to measure two phase flow rate is introduced. By using this method, the anti-interference capability, stability and cost/performance ratio of the system are enhanced. The basic principle of this method is discussed and a measuring system is established to simulate the practical measuring condition. The results of the experimental analysis verified the feasibility of the method based on differential auto-correlation.
