An apparatus and method are described for use in the area of equalizing and measuring the quality of steam exiting multiple branches in a two-phase distribution system. The system utilizes fluid level elevational differences to provide a self-correcting mechanism so that the system may be utilized regardless of incoming fluid quality or pressure. The system does not require an inlet seperator. A system having a T-junction with upper and lower manifolds is described. Also described is a system having a differential liquid bypass and vapor branch with flow restrictions. The flow restrictions may be an orifice plate, a venturi, or a control valve.
