Various multi-phase flow system is commonly used in industrial process, and it isnecessary to measure and control the flow velocity for optimizing the performance of the process. But traditional flow measurement technique by turbines, pressure gauges, voltex detection,and so on cannot be used in the multi-phase flow system. In this study, some experiments werecarried out to optimize flow measurement technique based on the cross-correlation function withtwo sealed gamma sources for multi-phase flow system. Some air was inserted in the lab-scaleflow system for making the liquid-air two-phase flow system, and the reference flow velocity wasmeasured by radiotracer technique to compare to the results of the cross-correlation technique. The first result shows that the shorter the distance between two detectors is, the better resultthe technique provide because the distribution of second particle in the flow could be changedbetween the detectors. The second result shows that the wider width of collimator holes which isperpendicular to the flow direction provide the more accurate velocity.
