Specifies requirements for volumetric chamber and turbine meters with nominal flow rates not exceeding 40 kL/h and 250 kL/h, respectively, which may be fitted with electronic output devices (EOD). These meters 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 and pressures not exceeding 30 degrees Celsius and 1400 kPa, respectively.

This Standard specifies requirements for volumetric chamber and turbine meters with nominal flow rates not exceeding 40 kL/h and 250 kL/h, respectively, which may be fitted with electronic output devices (EOD). These meters are intended for installation in water services to measure, within the accuracy limits of the class, thevolume of cold potable water at working temperatures and pressures not exceeding 30C and 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.NOTE: Purchasing guidelines are given in Appendix A.
