ISO 5167-1 is a standard issued by the International Organization for Standardization (ISO) that provides guidelines for the measurement of flow rates in closed conduits using orifice plates, nozzles, and venturi tubes. The full title of the standard is “Measurement of fluid flow by means of pressure differential devices inserted in circular cross-section conduits running full – Part 1: General principles and requirements.”
In simple terms, ISO 5167-1 outlines the principles and requirements for using certain types of flow measurement devices (orifice plates, nozzles, and venturi tubes) to measure the flow rate of liquids and gases in pipes or closed conduits. These devices work based on the measurement of pressure differential across a constriction in the flow path. By knowing the geometry of the device and the pressure difference, the flow rate can be determined using the equations and methods specified in the standard.
The ISO 5167-1 standard is widely used in industries where accurate flow measurements are critical, such as oil and gas, chemical processing, water supply, and many others. It ensures consistent and reliable flow measurements when properly implemented according to its guidelines.
