    Abstract - (Show below) - (Hide below)

    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 specified accuracy limits, the volume of cold drinking water at working temperature range of 0.3 degrees Celsius to 30 degrees Celsius and pressure not exceeding 1400 kPa, respectively.

    Scope - (Show below) - (Hide below)

    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 specified accuracy limits, the volume of cold drinking water at working temperature range of 0.3°C to 30°C and pressure not exceeding 1400 kPa, respectively. This Standard is applicable to combination meters that are capable of operating at intermittent temperatures of at least 50°C, which may be fitted with electronic output devices (EOD), are self-contained and capable of continuously determining, within the accuracy limits of the meter the volume of cold drinking water that has flowed through them, and are continuously indicating the volume on a cumulative basis. Such volume being 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. Means for demonstrating compliance with this Standard are given in Appendix A NOTE: Purchasing guidelines are given in Appendix B.
