1.1 This practice covers flow conditioners that produce a fully developed flow profile for liquid and gas phase fluid flow for circular duct sizes 1to 60-in. (25.4to 1525-mm) diameter and Reynolds Number (Re) ranges from transition (100) to 100 000 000. These flow conditioners can be used for any type of flow meter or development of a fully developed flow profile for other uses. 1.2 The central single-hole configuration that is derived using fundamental screen theory is referenced as the flow conditioner described herein. 1.3 Piping lengths upstream and downstream of a flow conditioner are considered a critical component of a flow conditioner and constitute the complete flow conditioner system. 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

随着通信技术的发展,供水行业引入了无线远传水表系统,在解决入户抄表难、收费难问题的同时,还可以获得较优的抄表效果。但现阶段上海地区还未对无线远传水表系统提出相应的技术规范,这也导致了无线远传水表系统在应用中无法执行统一的标准,使得无线远传水表系统的质量、施工等无法得到保障,成为制约供水行业信息化建设发展的瓶颈之一。制定民用无线远传水表应用技术规范能提高用水抄表效率、数据传输准确度、稳定性,提高安装和使用的可操作性,规范产品供应商的生产应用指标,提高行业管理水平,对供水行业的信息化发展有着重要作用,并能产生极大的经济和社会效益。 本规范从无线远传水表系统的功能、安装与调试、验收、运行维护等方面做出了相应的规范,提高用水数据输送效率、计量的准确率以及安装使用安全,对上海供水行业信息化建设发展和促进有着重要意义。

This document specifies a method for the determination in a closed conduit of the volume rate of flow of a regular flow a) of a fluid of substantially constant density or corresponding to a Mach number not exceeding 0,25, b) with substantially uniform stagnation temperature across the measuring cross-section, c) running full in the conduit, and d) under steady flow conditions. In particular, it deals with the technology and maintenance of Pitot static tubes, with the calculation of local velocities from measured differential pressures and with the computation of the flow rate by velocity integration.
