12、tandardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the ri
13、ght to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Internationa
14、l Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as
15、an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

16、 22158 was prepared by Technical Committee ISO/TC 30, Measurement of fluid flow in closed conduits, Subcommittee SC 7, Volume methods including water meters. BS ISO 22158:2011ISO 22158:2011(E) ISO 2011 All rights reserved vIntroduction The need to be able to communicate with metered systems has beco
17、me apparent. This International Standard seeks to address the issues associated with water meters, but can be used in conjunction with other metered systems such as gas and electricity supply that utilize common interfaces and protocols. During recent years, an increasing number of electronic device
18、s have been introduced into water meters, e.g.: pulse output systems; absolute encoded systems; bidirectional addressable bus systems. Currently, there is no clear definition of either hardware interfaces or the protocols of such systems and this International Standard attempts to solve the problems
19、 arising from this. Existing technology for water meter communications can be split into three distinct groups, which are defined as follows: pulse output water meters referred to in this International Standard as type A; non-addressable water meters referred to in this International Standard as typ
20、e B; addressable water meters referred to in this International Standard as type C. This International Standard describes the general requirements of the protocols and electronic interfaces for water meters. It is intended to provide the necessary guidance for designers of meter registers and readin
21、g equipment. The provisions have been determined by analysing applications currently in use and by consultation within the water industry. However, the list of applications is not exhaustive.

This International Standard onl
