- This part of ISO 4064 deals with terminology, technical characteristics, metrological characteristics and pressure loss. It applies to water meters of various metrological classes (see clause 5) which can withstand permanent flow-rates from 0.6 m3/h to 4000 m3/h, maximum admissible working pressures (MAP) equal to or greater than 10 bar and a maximum admissible temperature (MAT) of 30 °C. The recommendations of this part of ISO 4064 apply to water meters defined as follows: self-contained integrating measuring instruments continuously determining the volume of water flowing through them, employing a direct mechanical process involving the use of volumetric chambers with mobile walls ("volumetric" water meters) or the action of the velocity of the water on the rotation rate of a moving part ("velocity" meters). Legal requirements take precedence over the recommendations of this part of ISO 4064.
