液态烃 动态测量 容积计量系统的统计控制

[中文适用范围]： 在动态测量系统中，液态碳氢化合物仪表的性能将随着流动条件的变化而变化，即。 流量、粘度、温度、压力、产品密度以及机械磨损。 已准备作为建立和监测此类仪表性能的指南，使用适当的统计控制程序进行中央和在线证明。 这些程序可应用于任何类型的体积或质量计量系统进行的测量。 描述了收集数据所遵循的程序，控制限值是基于这些程序。 [外文原描述]： In dynamic measuring systems the performance of meters for liquid hydrocarbons will vary with changes in flow conditions, viz. flowrate, viscosity, temperature, pressure, density of product, and with mechanical wear. Has been prepared as a guide for establishing and monitoring the performance of such meters, using appropriate statistical control procedures for both central and on-line proving. These procedures may be applied to measurements made by any type of volumetric or mass metering systems. The procedures to be followed for collecting data, on which the control limits are based, are described.
