Scope

This document specifies the test conditions, flow measurement devices, and their on-site installation and commissioning, as well as the technical requirements for flow measurement of hydroelectric turbines, storage pumps, and pump-turbines using the ultrasonic propagation time method. This document is applicable to the on-site flow measurement of hydroelectric turbines, storage pumps, and pump-turbines with a pressure-bearing circular cross-section and a flow channel diameter of not less than 0.8 m, which use either internally mounted or externally inserted transducers. For rectangular cross-sectional flow channels, the requirements can be referenced for implementation.
