Xie Dailiang, Liang Guowei, Wang Fang
Abstract:
A multi-loop flowmeter is designed for the flowrate measurement of the gas-liquid two-phase flow. The differential pressure signals can be collected from the multiloop sensor at different positions. The total flowrate measurement model is established according to the average differential pressure value obtained from the optimal position. The time serial of the signals is obtained by using the high speed data capture device. A non-dimensional characteristic value related to the root-mean-square of the dynamical differential pressure signals is obtained. The relationship between this value and the volume void fraction is established. The online measurement of the volumetric void fraction of gas-liquid two-phase is realized and the flowrate of the gas phase and the liquid phase are measured. The experiments showed that the results were satifactory.
