Abstract： The Coriolis mass flowmeter has become one of the fastest developing flowmeters both domestically and internationally due to its ability to achieve high-precision direct mass flow measurement. The article first introduces the basic principle and performance of Coriolis mass flow meters， then summarizes the signal processing methods of Coriolis mass flow meters at home and abroad， and based on this， looks forward to its development trends.

Key words： coriolis mass flow meter; signal processing; discrete fourier transform; relevant laws; hilbert transform
