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. Information is also given for square-edged orifice plates
and nozzles under conditions outside the scope of ISO 5167 series.
