GB/T 11826-2002 specifies the rotor flow velocity meter. The standard clarifies the terms and definitions of the rotor flow velocity meter and defines its application scenarios. In terms of technical requirements, strict indicators are proposed for the key performance of the instrument measurement Flow velocity range, accuracy, start-up Flow velocity, etc., to ensure accurate measurement results. Detail the structural design of the instrument, the technical standards of the rotor and Sensors and other components. The standard specifies comprehensive test methods, covering laboratory calibrated testing, on-site actual measurement testing and other processes. At the same time, inspection rules are formulated, including factory inspection and type inspection. This standard provides a basis for the production, testing and use of the rotor type Flow velocity meter to ensure its accurate measurement of water flow velocity in hydrological monitoring, hydraulic engineering and other fields.
