ActiveMeasurement of fluid flow by means of pressure differential devices inserted in circular cross-section conduits running full - Part 4: Venturi tubes
用安装在圆形截面管道中的差压装置测量满管流体流量 第4部分：文丘里管
Application Summary AI generated
This standard specifies the geometry, installation requirements, and calculation methods for Venturi tubes used to measure fluid flow in circular pipes under full-flow conditions. It is applied in industrial process control, water supply systems, and natural gas metering where accurate differential pressure-based flow measurement is required. The standard ensures consistent performance across testing and operational environments by defining the Venturi tube's dimensions and pressure tap locations.
