标准摘要
[中文适用范围]： 本文件规定了基于差压原理的流量计量装置所依据的测试与报告程序。该程序旨在为行业提供一套可比性描述，用于说明在相似工况下这些装置对单相流体流动的测量能力。本测试程序的目标包括：1. 确保使用任何差压式流量计的用户了解其在适用雷诺数范围或经测试定义的范围内所具有的性能特性；2. 促进对新技术的理解与推广；3. 提供一种标准化手段以验证制造商的性能规格；4. 在标准化测试程序下，提供关于差压计量装置中一次元件相对性能特性的信息；5. 量化测量不确定度。 [外文原描述]： Defines the testing and reporting protocols for flow measurement devices based on the detection of a pressure differential that is created by the device in a flowing stream. This protocol is designed to supply industry with a comparable description of the capabilities of these devices for the measurement of single-phase fluid flow when they are used under similar operating conditions. The objectives of this Testing Protocol are to: 1. Ensure that the user of any differential pressure flow meter knows the performance characteristics of the meter over a range of Reynolds numbers as applicable or defined by tests, 2. Facilitate both the understanding and the introduction of new technologies, 3. Provide a standardized vehicle for validating manufacturer’s performance specifications, 4. Provide information about relative performance characteristics of the primary elements of the differential pressure metering devices under standardized testing protocol, 5. Quantify the uncertainty o
