瓦斯抽放管路流量测量的多孔孔板流量计性能
Properties of multi-hole orifice flowmeter measuring gas flow in gas drainage pipline
摘要
Abstract
This paper is an alternative to standard orifice which suffers from a stringent requirement for straight pipe length and higher cost in gas drainage pipeline, by proposing multi-hole orifice to measure gas flow in gas drainage pipeline according to the construction and principle of multi-hole orifice. Experiments prove that the multi-hole orifice boasts the advantages such as a lower requirement for straight pipe length, wider range, higher linearity and easier application in coal mine enterprise.关键词
