Measurement of flow rate and volume of fluid and gas by means of standard pressure differential devices". The complex of standards applies to measurement of flow rate and volume of fluids and gases by means of the pressure differential method. The complex of standards defines requirements to the geometrical dimensions and to the conditions of application of a pressure differential device inserted in circular-cross section conduits running full with a single-phase medium at subsonic speed of flow. Part 3 of the complex of standards deals with technical requirements to ISA 1932 nozzles, long radius nozzles and Venturi nozzles. Product Description popup.authors popup.nrat_date 2020-04-02 Close
