Specifies the geometry and method of use for orifice plates, nozzles and Venturi tubes for the determination of fluid flow rate in a closed conduit running full. Information for the calculating of a flow rate and its associated uncertainty is included. The Standard applies to conduits with diameters within the range 50 mm to 1200 mm inclusive. It is identical with and has been reproduced from ISO 5167-1:1991.

Measurement of fluid flow in closed conduits, Part 1.1: Pressure differential methods — Measurement using orifice plates, nozzles or Venturi tubes — Conduits with diameters from 50 mm to 1200 mm
