STEAM WETNESS MEASUREMENT DEVICE

摘要

Provided is a measurement system for measuring wetness of the gas phase of a two phase flowing fluid. The measurement system includes a container for containing the fluid flow having an inner surface with an average cross sectional area, a liquid film measurement device adapted to measure a flowrate of a liquid film of the two phase fluid through the container, an Electrical Capacitance Tomography device that has a plurality of electrodes located in the container, and a computer adapted to calculate the flowrate of the liquid film in the container. The measurement system calculates wetness of the gas phase based on a measurement of the Electrical Capacitance Tomography device and the calculated liquid film flowrate.
