Abstract	A new instrument, an average BDFT (birectional flow tube), is proposeded to measure the area-averaging single- and two-phase flow rates. This average BDFT is capable of being applicable to the low or bidirectional flow condition. In this study, an advanced flow meter applicable to large diameter piping system was developed using the average BDFT. This flow meter can be used to measure the flow rate of discharged gas having fine floating particles in the stack of a chemical reactor or a large-sized boiler. Also it can be applied to the large-sized industrial piping system having flow of oil without structural instability. As a first step of commercialization, we designed and manufactured the flow meters which are applicable to piping system having diameter of 200mm and 500mm. The calibration test results indicated that this flow meter has linaerity within 0.5% in the Re number range of above 10,000 where is meaningful in terms of application. The flow analyses results using CFX code demonstrate that the flow meter has a good linearity with various design features. Therefore, it is quite reasonable to select the typical design of the average BDFT for a convenience of the experimental conditions and pipe arrangements. The structural analyses results imply that this flow meter is applicable to the various flow rate conditions.
