英文摘要:

      In order to reduce the noise level of the Coriolis mass flowmeter,wavelet transform is adopted as pre-filter 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.
