A steam quality meter includes a pipe with an inlet and an outlet. A rod is located within the pipe between the inlet and the outlet. The rod defines an annular flow passage between an outer wall of the rod and an inner wall of the pipe. A mixing device is located within the pipe between the inlet and an upstream end of the rod. Spaced sensors are located within the annular flow passage. Each sensor is configured to sense capacitance and/or impedance of steam flowing through the annular flow passage.

Methods and systems are disclosed for interpreting multi-phase fluid flow in a conduit, such as a pipe in a wellbore. The method involves curve fitting holdup data sets and velocity data sets together wherein the second curve comprises a shape mutual to the first curve with an independent gain and an independent offset, and determining flow rates through the pipe.

A device for detecting a non-condensable gas including a tube having an open end and a closed end, the tube and the closed end being closed with respect to a fluid, the open end open to allow the fluid to move into and out of the tube, and the tube configured to allow a condensed portion of the fluid to be removed from the tube by gravitation. The device includes a heat sink configured to extract heat from the tube at the closed end. The device further includes a heat source configured to supply heat to the open end of the tube and at least one thermometer configured to measure a temperature at a specific portion of the device or the fluid inside the tube.

A turbine engine assembly includes a core engine that generates an exhaust gas flow, a condenser where water is extracted from the exhaust gas flow, an evaporator where heat is input into the water that is extracted by the condenser to generate a first steam flow, a first steam turbine where the first steam flow is expanded and cooled to generate a first cooled flow, a bypass passage that defines a path for the first steam flow around the first steam turbine, and a superheater where at least one of the first steam flow and the first cooled flow is reheated to generate a second steam flow.
