科氏質(zhì)量流量計信號處理方法探究
摘要：科氏質(zhì)量流量計因能實現(xiàn)高精度的直接質(zhì)量流量測量，成為目前國內(nèi)外發(fā)展最為迅速的流量計之一。文章首先介紹了科氏質(zhì)量流量計的基本原理與性能，隨后綜述了國內(nèi)外關(guān)于科氏質(zhì)量流量計的信號處理方法，并在此基礎(chǔ)上對其發(fā)展趨勢進行了展望。

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
