摘要
为了提高科里奥利质量流量计的降噪水平,采用以小波变换作为前置滤波器来抑制噪声干扰。以分析小波变换为基础,阐述了小波变换应用在科氏流量计上的可行性,给出了实现方案,并做了相关的现场实验。通过实验结果表明所研究的方法是可行且有效的。
In order to reduce the noise level of the Coriolis mass flowmeter, wavelet transform is adopted as prefilter to suppress noise jamming. Based on wavelet transform, the feasibility of the wavelet transform on Coriolis mass flowmeter is expounded. The implementation is put forward, and relevant experiment has been done. Results show that the method is feasible and effective.
