Provides requirements for volumetric chamber and turbine meters with permanent flow rates not exceeding 6.5 kL/h and which may be fitted with electronic output devices (EOD), incorporating two independent non-return valves, (Dual CVs) for low hazard protection of potable water.

This Standard specifies requirements for volumetric, multi-jet, and single-jet meters incorporating two independent non-return valves (dual CVs) for low hazard protection of potable water supply. Water meters with integral dual check valves are intended for installation in water services to measure, within the accuracy limits of the class, the volume of cold potable water at working temperatures in the ranges of 0.3°C to 30°C and pressures not exceeding 1400 kPa, respectively. This Standard is applicable to meters that are self-contained and capable of continuously determining, within the accuracy limits of the class, the volume of cold potable water that has flowed through them, and that are continuously indicating the volume on a cumulative basis. Means for demonstrating compliance with this Standard are given in Appendix A NOTE: Purchasing guidelines are given in AS 3565.1.
