适用范围：1.1 This standard details the recommendations for measurement of fluid flow by means of orifice plate or nozzle placed in a pipe line in the case of in-compressible, non-pulsating, single phase flows. This standard also describes the shape and method of use, of certain of these devices on which direct calibration experiments have been made, sufficientin number and quality to enable coherent systems of use to be based on their results.1.2 The devices introduced in the pipe are called ' primary elements' which term includes the pressure taps, all other instruments or devices required for metering being known as ' secondary devices'. This recommendation covers the pri-mary elements.
