根据国家水表检定规程要求 ,在检定水表示值误差时 ,应在“公称流量”、“分界流量”、“最小流量”、“始动流量”４个流量点进行检测。不同口径水表的各个流量点 ,都有各自相应的流量和用水量 ,因此水表在检定示值误差时都有各自相应的理论耗时。如果在检定中某流量点检定不
According to the requirements of the national meter verification procedures, when verifying the indication error of water, it should be tested at four flow points of “nominal flow rate”, “demarcation flow rate”, “minimum flow rate” and “initial flow rate”. Different caliber water meter of each flow point, has its own corresponding flow and water consumption, so the meter when testing the indication error has its own corresponding theoretical time-consuming. If the check in a certain flow point test is not
