Measurement of fluid flow by means of pressure-differential devices. Guidelines for the specification of orifice plates, nozzles and Venturi tubes beyond the scope of ISO 5167. | Status: Superseded, Withdrawn

1 Scope This document describes the geometry and method of use for conical-entrance orifice plates, quarter-circle orifice plates, eccentric orifice plates and Venturi tubes with 10,5° convergent angles. Recommendations are also given for square-edged orifice plates and nozzles under conditions outside the scope of ISO 5167.

NOTE The data on which this document is based are limited in some cases.
