请注意，本标准的翻译版本中可能不包括任何附录或勘误表。本文件概述了校准仪的基本元件，这些元件将仪表脉冲累积为校准仪内的位移元件，并在探测器开关之间移动。它提供了目前使用的位移校准仪类型的设计和安装细节。所讨论的校准仪设计用于在单相液态烃的动态操作条件下验证测量装置。

Please note that any addenda or errata may not be included in translated editions of this standard.This document outlines the essential elements of provers that accumulate meter pulses as a displacing element within the prover travels between detector switches. It provides design and installation details for the types of displacement provers that are currently in use. The provers discussed are designed for proving measurement devices under dynamic operating conditions with single-phase liquid hydrocarbons.
