Organization: CEI
Publication Date: 1 August 2015
Status: active
Page Count: 70
ICS Code (Water supply systems): 91.140.60
scope:

The part of ISO 4064 specifies technical characteristics and pressure los 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 MPA 1) [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 applies 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 optional. However, national or international regulations may made some ancillary devices mandatory in relation to the utilization of the water meter.
