Abstract  With the near infrared spectral analysis technology, the relationship between the near-infrared spectral absorption characteristics and water phase volume containing rate is studied. First, according to the Lambert-Beer’s law, the static test was analysied of and obtain a function of the relationship between the measured voltage value and the water layer thickness by origin fitting was obtained. Then, the pipeline model was analysied and the relationship between the water layer thickness and water phase volume fraction was get. The water layer thickness is an intermediate amount, through the online experiment of vertical pipe slug flow and bubbly flow, the real-time measurements of varieties of different water phase volume ratio were achieved. Eventually the mathematical relationship between the near infrared spectral absorption characteristic and water volume fraction can be gained.
