中文摘要：

气液两相流由于其自身的复杂性，流型、流量等流动参数的测量一直是研究的重点和难点。应用多传感器数据融合技术测量气液两相流可以从多角度揭示流体信息，提高流动参数的测量精度。多传感器系统主要由截面信息测量系统和V型内锥式流量计构成，在利用相关技术对截面测量信息与V型内锥式流量计的测量数据进行时间融合的基础上，对水平管气液塞状流经行了分段式的流量测量。测量中将气塞和液塞分开计算，并引入了等效干度的计算，通过对实验结果进行的误差比较，验证了该方法是可行的，而且能一定程度上提高测量精度。

英文摘要：

The measurement of real-time parameter of gas/liquid two-phase flow becomes a difficult issue in the field of engineering and science, because of the complexity and variability. Application of multi-sensor data fusion could reveal more information about the flow process from multiple aspects and increase the accuracy of the measurement. The multi-senor system mainly consists of a cross-section information system and a V-cone flow meter. Measurement of mass flow rate of gas/liquid two-phase flow in a horizontal pipe is carried out based on the time fusion of the experimental data from the cross-section information system and V-cone flow meter. Gas plug and water plug are treated separately and the equivalent quality of gas calculation is put forward in the measurement. The experimental result shows that this method is efficient and able to increase the measurement accuracy to a certain extent. The experimental error is acceptable
