The mathematic model is studied to measure horizontal gas liquid two phase bubble flow with turbine flowmeter The index number of virtual velocity profile of mixed fluid in the horizontal annulus pipe is presented The influence for bubble of mixed fluid to blade by the drag force is analyzed The curve between the index number of virtual velocity profile and gas volume fraction are obtained On the two phase flow facility, the validity of the mathematic model is verified by experimental results.
