Specifies the requirements for combination meters, with nominal flow rates not exceeding 150 kL/h and consisting of one small meter and one large meter in parallel, with a changeover device. These combination meters are intended for installation in water services, to measure within the accuracy of its Class, the volume of cold potable water at working temperatures and pressures not exceeding 30 degrees Celsius and 1400 kPa, respectively. These combination meters shall be capable of operating at working temperatures of at least 50 degrees Celsius and may be fitted with electronic output devices (EOD).

This Standard specifies requirements for combination meters with nominal flow rates not exceeding 150 kL/h and consisting of one small meter and one large meter in parallel, with a changeover device. These combination 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 30C and 1400 kPa, respectively. This Standard is applicable to combination meters which are capable of operating at working temperatures of at least 50C and may be fitted with electronic output devices (EOD), which are self-contained and capable of continuously determining within the accuracy limits of the Class, the volume of cold potable water which has flowed through them, and which are continuously indicating the volume on a cumulative basis. Such volume is equal to either -(a) the sum of the volumes shown on the registers of the small and large meters; or(b) the volume shown on the single register for both the small and large meters.NOTE: Purchasing guidelines are given in Appendix A.
