The work of preparing International Standards is normally

31、carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the wo

32、rk. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the diff

33、erent approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2, www.iso.org/directives.Attention is drawn to the possibility that some of the elements of this document may be

38、 the volume of cold potable water and hot water flowing through a fully charged, closed conduit. These water meters incorporate devices which indicate the integrated volume.This part of ISO 4064 specifies criteria for the selection of single, combination and concentric water meters, associated fitti

39、ngs, installation, special requirements for meters, and the first operation of new or repaired meters to ensure accurate constant measurement and reliable reading of the meter.In addition to meters based on mechanical principles, this part of ISO 4064 also applies to water meters based on electrical

40、 or electronic principles, and to water meters based on mechanical principles incorporating electronic devices, used to measure the volume of cold potable water and hot water. It also applies to electronic ancillary devices. Ancillary devices are optional. However, national or international regulati

41、ons may make some ancillary devices mandatory in relation to the utilization of the water meter.The recommendations of this part of ISO 4064 apply to water meters, irrespective of technology, defined as integrating measuring instruments continuously determining the volume of water flowing through th

Conversion is related to either change of flow pattern, change of flow direction or extension of seat depth.4 Criteria for the selection of water meters4.1 General considerationsThe type, metrological characteristics

48、, and sizes of water meters should be determined according to the operating conditions of the installation and the environmental class(es) demanded, taking into account, particularly, the following: the available supply pressure; the physical and chemical characteristics of the water, including wate

49、r temperature and water quality (suspended particles); the acceptable pressure loss across the meter; the expected flow rates: the flow rates Q1and Q3of the meter (as defined in ISO 4064-1:2014|OIML R 49-1:2013, Clause 3) shall be compatible with the expected flow rate conditions of the installations, including the water flow direction(s); the suitability of the meter type for the intended mechanical, climatic, electrical, and hydraulic conditions, including ambient rel
