Flow-through Measurement System Based on Virtual Instrument for Granular Material Transporting in Tee Branch Pipes

摘要

This paper introduces the flow-through measure system for gas-powdery mixture granular material transporting in tee branch pipes based on virtual instrument techniques, including the techniques of dual-energy gamma ray attenuation and cross-correlation velocity measure technology. The structure of the system is present. According to the principle of the cross-correlation velocity measurement, the arithmetic with graphics program is described in the paper. The experiment processes for the flow-through measure system and experiment results are described in this article.
