Scope: This part of GB/T 2624 defines terms and symbols, and determines the general principles and calculation methods for measuring full pipe fluid flow with differential pressure devices (orifice plates, nozzles and Venturi tubes) installed in circular cross-section pipes. This standard also specifies the general requirements for measurement, installation and methods for determining the uncertainty of flow measurement. This section also defines the range of pipe sizes and Reynolds numbers for which these differential pressure devices are applicable. GB/T 2624 (all parts) applies only to single-phase flow that maintains subsonic velocity throughout the measurement section. It is not suitable for the measurement of pulsating flow.
