摘要
目前天然气计量己制定了许多相关的国家标准、行业标准和计量检定规程等,但未形成完整体系,与国外相比尚有较大差距。本文着重探讨了天然气孔板流量测量中准确度要求和不确定度,分析了影响测量不确定度的几种因素。
At the current natural gas measurement has a lot of relevant national standards, industry standards and metrology verification regulation, but has not yet formed a complete system, compared with foreign countries there is a big gap. This paper focuses on the natural gas orifice plate flow measurement accuracy requirements and uncertainty, analyzes several factors that effect measurement uncertainty.
