It applies to water meters that can withstand maximum admissible working pressures (MAP) W 1 MPa1) (0,6 MPa for meters for use with pipe nominal diameters, DN W 500 mm) and a maximum admissible temperature, MAT, for cold potable water meters of 30 ºC and for hot water meters up to 180 ºC, depending on class. ; ; 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 actual volume flow of cold potable water and hot water. It also applies to electronic ancillary devices. Generally ancillary devices are optional. ; ; The specifications 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 them. ; ; NOTE National regulations may apply in the country of use.
