Scope
Main technical content: Due to various reasons such as difficulty in disassembling and inability to stop operation during use, it is difficult to send large-diameter electronic water meters to laboratories for verification. Online calibration is the first choice for solving the problem of traceability of electronic water meters. This standard specifies online calibration methods such as the standard meter method and the collection method. Among them, the method of using an external clamp ultrasonic flow meter as a standard meter to conduct online calibration of electronic water meters is currently widely used in the industry
