石油测量系统.第2部分:管道校准仪的设计、校准和操作

[中文适用范围]： 本文件描述了不同类型的管道检定器（也称为排量检定器），目前在使用中包括球形（球型）检定器和活塞式检定器，在单向和双向形式下运行。适用于以常规、减少体积和小体积模式操作的检定器。 本文件为以下内容提供指南：——各类型管道检定器的设计；——校准方法；——各种类型检定器的安装和使用；——检定器与不同类型的流量计之间的相互作用；——用于导出被测量液体体积（见附录A）的计算；——在量值传递和 custody transfer 应用中预期接受标准，作为管道检定器校准以及用于证明流量计（见附录C）的指南。 本文件适用于原油和轻质烃类产品的使用，这些产品在环境条件下为液体。 所阐述的原则适用于更广泛范围的流体，包括水。所阐述的原则也适用于低蒸汽压、冷却和 cryogenic 产品，然而，使用这些产品可能需要额外的指导。 [外文原描述]： This document provides descriptions of the different types of pipe provers, otherwise known as displacement provers, currently in use. These include sphere (ball) provers and piston provers operating in unidirectional and bidirectional forms. It applies to provers operated in conventional, reduced volume, and small volume modes. This document gives guidelines for: — the design of pipe provers of each type; — the calibration methods; — the installation and use of pipe provers of each type; — the interaction between pipe provers and different types of flowmeters; — the calculations used to derive the volumes of liquid measured (see Annex A); — the expected acceptance criteria for fiscal and custody transfer applications, given as guidance for both the calibration of pipe provers and when proving flowmeters (see Annex C). This document is applicable to the use of pipe provers for crude oils and light hydrocarbon products which are liquid at ambient conditions. The principles apply across applications for a wider range of liquids, including water. The principles also apply for low vapour pressure, chilled and cryogenic products, however use with these products can require additional guidance.
