Abstract：

Particle Imaging Velocimetry (PIV) is a set of modern flow field measurement technology integrating flow visualization and full flow field flow parameter quantitative test. To explore the feasibility of application of the device in pipeline gas metering, conducted is quantitative study on effect of flow pattern in gas pipeline on flow meter performance, PetroChina Southwest Oil and Gas Field Company has built a set of PIV test system suitable for closed gas pipeline in DNl00 natural gas pipeline. The PIV system can measure the pipe fluid flow and fluid velocity in different directions. Introduced is application of the PIV system in five kinds of installation conditions for measuring tube cross section flow and relative errors are obtained for standard device flow. Discussed is the possibility that the PIV system is developed into a new type of natural gas flow measurement device.
