The Standards Australia Committee CE-24 recently issued a suite of draft AS ISO Flow Measurement Standards for public comment. ISO standard 5167 has seven parts and covers the measurement of fluid flow by means of pressure differential devices inserted in circulation cross section conduits running full.
The various pressure differential devices covered include nozzles and venturi nozzles, orifice plates, venturi tubes, cone meters, and wedge meters. These AS ISO 5167 standards are expected to be published within the next two months and will be direct adoptions of the current ISO standards.
For the record, in the past an Australian Standard that was a direct adoption of an ISO standard was known by a separate AS number, the ISO number was secondary. ISO 5167 is included in the bibliography of the pump test standard AS ISO9906:2018 and the fire pump standard AS2941-2013.
