基于小波变换的三相流测量技术的研究

The Study of the Technique for Three Component Flow Measurement with Wavelet Transformation

以电容传感器在线检测输油管道中油／水／气流体信号为基础，分析了测量原理．提出了基于小波变换的三相流流体信号的后处理的原理及方法。

The wavelet transformation is used to analyzing signal for its good time frequency characteristics,the signal is obtained on line from the transducer whose operating principle is based on the detection of changes in capacitance of a three component oil/water/gas flow.Its feasibility is proved by the analyzing result.
