Deals with terminology, technical characteristics, metrological characteristics and pressure loss. Applies to water meters of various metrological classes which can withstand permanent flow-rates from 0,6 m3/h to 4000 m3/h, maximum admissible working pressures equal to or greater than 10 bar and a maximum admissible temperature of 30 °C. Legal requirements take precedence over the recommendations of this part.
