Study on the Tests of Large-Bore Flow Measurement Using FJPE-Type Gauging Pipes

Zhou Guo-xiang, Wang Jing-an, Li Chunhui
  • Abstract:
    Several tests using FJPE-type gauging pipes for improving the accuracy of large-bore flow measurement have been described herein. The measuring test of non-fully developed pipe flow, which is formed in the elbow, is discussed especially, including research processes, part of data-processing result, and flow velocity profiles at the cross-section of pipes. The initial results indicate that, measurement of large-bore flow by varied-bore pipe is of significant flow-rectifying effects, which reduces the length-requirements of straight tubes as well. The gauge constant fluctuated little within the larger Reynolds number range. This kind of research provides a new method for large-bore flow measurement.
