Abstract
Methods and apparatus are disclosed for adjusting, measuring and controlling the vapor/liquid ratio of wet steam in the output line of a pipe junction in a two phase fluid flow line. The vapor phase and liquid phase of the two phase fluid are separated in the main flow line of the junction and the volume flow rate of each phase measured. The two phases are recombined at the plane of symmetry of the output line of the junction and the liquid flow rate is controlled and varied through an adjustable valve in a liquid phase bypass flow line.
