ISO 5167-3:2022 is an international standard that provides guidelines for using nozzles and Venturi nozzles to measure fluid flow in pipes. It specifies the geometry, installation, and operating conditions of these devices for determining the flowrate of fluids in a fully-filled conduit. The standard is applicable to subsonic, single-phase fluid flows within defined limits of pipe size and Reynolds number.
