标准摘要
[中文适用范围]: 本文档适用于密度范围为350至688千克/立方米(在60华氏度下相对密度为0.350至0.689)的单相动态液体质量测量系统的选型、设计、安装、运行与维护。本文件涵盖的质量测量系统包括推断式质量测量(将工况下的体积与相近条件下的密度相结合以获得测量质量)以及科里奥利质量测量。密度低于350千克/立方米或高于688千克/立方米(在60华氏度下相对密度低于0.350或高于0.689)的液体以及低温流体(温度低于约零下50华氏度)不属于本文件适用范围,但文中所述原理或可适用于此类介质。文档内容还涵盖采样设备及技术,包括用于确定样品产品成分的分析方法的相关标准。文中涉及的状态方程与关联式用于计算产品密度。 [外文原描述]: This document serves as a reference for the selection, design, installation, operation and maintenance of single-phase dynamic liquid mass measurement systems that operate in the 350 to 688 kg/m3 (0.350 to 0.689 relative density at 60°F) density range. The mass measurement systems within the scope of this document include inferred mass measurement, where volume at flowing conditions is combined with density at similar conditions to result in measured mass, as well as Coriolis mass measurement. Liquids with density below 350 and above 688 kg/m3 (below 0.350 and above 0.689 relative density at 60 °F) and cryogenic fluids (colder than approximately –50 °F) are excluded from the scope of this document, but the principles described herein may apply to such streams. Sampling equipment and techniques are covered including standards for analytical methods used to determine the composition of the sampled product. Equations of state and correlations used to calculate the density of the product
