摘　　要：槽道式流量计从设计上满足了运动学相似。经过优化的纺锤体节流件是良好的流线体,避免了流动分离,阻力小,流动十分稳定。实验室标定结果和实际使用证明,槽道流量计具有极好的精确度和极强的适应性。文章就槽道式流量计工作原理、解决的相似性问题、尾流的流态、实流校准的结果等做一阐述与介绍,为槽道式流量计应用与天然气流量测量提供基础性的研究参考。The channel-type flowmeter meets the kinematic similarity in design.The optimized spindle-shaped throttling element is a well-streamlined body,which avoids flow separation,has low resistance,and ensures a very stable flow.The laboratory calibration results and practical applications prove that the channel flowmeter has excellent accuracy and strong adaptability.This paper elaborates and introduces the working principle of the channel-type flowmeter,the similarity problems it solves,the flow pattern of the wake,and the results of the actual flow calibration,providing a basic research reference for the application of the channel-type flowmeter and natural gas flow measurement.
