Solid Velocity Measurement of Using Spatial Filter and Wavelet Transform

摘要

The essential method for processing two phase flow signals is described based on spatial filter and wavelet transform. Firstly, spatial filtering effect of capacitance sensors is studied .Secondly, the relationship in solid velocity and band width is found .Thirdly, the capacitance sensors width of pass-band is gained by using the nature of wavelet transform filtering. Furthermore solid velocity is obtained. Finally, we give processing results of practical measured signals.
