Study on Using Correlation to Detect Phase Difference in Coriolis Flow Meter

YANG Jun~*,WU Qi-sheng,SUN Hong-qi(Dept of Information Engineering,Chang'an University,Xi'an 710064,China)  
An improved algorithm of using correlation to detect phase difference in Coriolis flow meter is described.It is based on the traditional way of using correlation to detect the phase difference in Coriolis flow meter.The new algorithm can overcome the frequency varying in Coriolis flow meter and reduce the error induced from non-period sampling.
