适用范围：This part of ISO 5167 defines terms and symbols and establishes the general principles for methods ofmeasurement and computation of the flowrate of fluid flowing in a conduit by means of pressure differentialdevices (orifice plates, nozzles and Venturi tubes) when they are inserted into a circular cross-section conduitrunning full. This part of ISO 5167 also specifies the general requirements for methods of measurement,installation and determination of the uncertainty of the measurement of flowrate. It also defines the generalspecified limits of pipe size and Reynolds number for which these pressure differential devices are to be used.ISO 5167 (all parts) is applicable only to flow that remains subsonic throughout the measuring section andwhere the fluid can be considered as single-phase. It is not applicable to the measurement of pulsating flow.
