1. Apparatus for determining the mass flow rate and the quality of pressurized steam flowing through a conduit which comprisesa choke member in said conduit having a flow passage of a diameter to constrict the flow of steam in the conduit to critical flow,an orifice plate in said conduit positioned upstream of said choke member to define an intermediate passage, and having an orifice diameter therethrough,means for measuring the pressure differential across said orifice plate,means for measuring the steam pressure in said intermediate passage, andmeans for determining the mean flow rate and the quality of the steam in said conduit in accordance with said pressure differential across the orifice plate and the pressure in said intermediate passage.
