Title
The Application of Frequency Domain and Time Domain Analysis on Vortex Flowmeter Signal Processing.
Abstract
The vortex flowmeter is widely used because of its many advantages. However, it is easily influenced by the noises caused by pipe vibrations and fluid turbulence. The digital processing methods can complement the drawbacks of the traditional methods. This paper adopted a frequency domain and time domain analysis method to the vortex flowmeter signal processing. In the paper, the basic principles of wavelet transformation and the signal processing based on the discrete wavelet transformation are given, the adjusting methods of center frequency of filter are studied, and the processing procedure and simulation result are carried out. A design method of the poly phase IIR filter banks is studied. The result shows that the wavelet transformation can reduce the noise effectively, and it's an effective method on vortex flowmeter signal processing.
