Abstract: Unequal phase splitting at branch T pipe junctions, wherein the branch line is of substantially lesser diameter than the main line, is substantially eliminated by structure (either a weir or sump) in the main line which collects at least a portion of the liquid phase and a bypass line which connects the weir or sump to the branch line downstream of a constriction creating a reduced pressure section in the branch pipe.

Abstract: A system by which a supplier of wet steam may allocate and measure the mass flow rate and quality of steam delivered to a demand user and one or more secondary users with the wet steam delivered to each user being measured for purposes of billing. Pressure regulator means between the demand customer and the secondary customers responsive to pressure changes caused by the amount of steam going to the demand customer. The demand customer thus being able to take from 0 to 100% of the steam generator output with the remaining steam being allocated to the secondary customers.

Abstract: A system for automatically controlling the quantity and quality of steam to a plurality of constant demand customers has a steam generating source, and pressure regulator means and steam mass flow measurement means between each constant demand customer and the steam generating source.

Abstract: Separation of wet steam into its liquid and vapor phases is facilitated prior to encountering a junction. The separated phases are recombined as the steam exits the respective arms of the junction.

Abstract: The separation of wet steam into its liquid and vapor phases, prior to encountering a pipe junction, is facilitated. The liquid phase is then recombined by aspiration to effectively behave as a single phase vapor of homogeneous density at the point where the flow stream is divided by the junction.
