    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.

    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.
