摘　　要：文章依据用能单位能源计量器具配备和管理通则相关标准,利用误差合成法,对钢铁企业计量装置准确度等级的下限进行理论推导。以便于更直观的判别计量装置的选用是否满足规范配置对计量器具的准确度要求,同时避免过度配置设备精度。文章还对误差合成法进行简要的介绍。In this paper,the lower limit of the accuracy level of metering devices in iron and steel enterprises is theoretically derived by using error synthesis method according to the relevant standards of general rules for the equipment and management of energy metering devices in energy using units.In order to more intuitively determine whether the selection of measuring device meets the accuracy requirements of the standard configuration for measuring instruments,and avoid over-configuration of equipment accuracy.The error synthesis method is also briefly introduced.

关 键 词：钢铁企业 流量相关计量装置 准确度等级 误差合成
