Abstract
The use of an orifice plate in series with a critical flow choke provides a method of measurement for both steam quality and mass flowrate. Neither the orifice plate or the choke alone can be used to measure steam quality and mass flowrate. However, an expression for steam quality through both devices is obtained by solving an independent mass flowrate equation for each device--an equation for wet steam through the critical flow choke and an equation for wet steam through a sharp edged orifice plate.
