瓦斯抽放管路流量测量的涡街流量计设计
Improvement of vortex flowmeter to measure gas flow in gas drainage pipeline
摘要
Abstract
This paper is an attempt to improve the K-factor of vertex flowmeter which stays constant only in a narrow scope, with a resulting restraint of the measurement range.The paper features the vortex flowmeter improved by adopting a nonlinear modified method of K-factor.Experiments indicate that the improved vortex fiowmeter boasts the measurement range of 6.05 ～497.79 L/h and the linearity of 1.111％.The improved vortex fiowmeter allows the measurement range to be effectively increased, with ensured accuracy and promises to come into use in the mine gas drainage pipeline.关键词
