APPLICATION OF MULTI-SENSOR TIME FUSION TO PLUG FLOW MEASUREMENT

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.
