This paper introduces some key issues in measurement algorithm of Coriolis Mass Flowmeter (CMF) by means of spectrum analysis on basis of Discrete Flourier Transform (DFT). It also presents several methods of improving the speed and the precision of calculation. In order to remove the noise, FIR filtering is used and Correlation is proposed. The results of simulation have proved the effectiveness of methods discussed in this paper.
