These water meters in

25、corporate devices which indicate the integrated volume.This part of ISO 4064 specifies technical characteristics and pressure loss requirements for meters for cold potable water and hot water. It applies to water meters which can withstand:a) a maximum admissible pressure (MAP) equal to at least 1 M

26、Pa1)0,6 MPa for meters for use with pipe nominal diameters (DNs) 500 mm;b) a maximum admissible temperature (MAT) for cold potable water meters of 30 C;c) a MAT for hot water meters of up to 180 C, depending on class.In addition to meters based on mechanical principles, this part of ISO 4064 also ap

27、plies to water meters based on electrical or electronic principles, and to water meters based on mechanical principles incorporating electronic devices, used to meter the volume flow of hot water and cold potable water. It also applies to electronic ancillary devices. As a rule ancillary devices are

28、 optional. However, national or international regulations may make some ancillary devices mandatory in relation to the utilization of the water meter.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applicat
