Patent ID: 8820175

Claim:
A sensor for two-phase flow measurements, comprising: a tube having axially opposed first and second open ends; an annular sensor mount secured about the first end of the tube, the sensor mount having a circular opening formed therethrough aligned and in open communication with the first open end of the tube; first and second annular flanges, the first annular flange being mounted on the tube adjacent the sensor mount and the open first end of the heated tube, the second annular flange being mounted on the tube adjacent the open second end thereof, the first and second annular flanges being adapted for forming a fluid-tight connection between a pair of pipe sections such that a two-phase fluid flowing through the pair of pipe sections continuously flows through the tube and the circular opening of the annular sensor mount; at least one heating element attached to the tube for heating fluid flow therein; a central temperature sensor mounted to the annular sensor mount and suspended centrally within the circular opening thereof for measuring temperature in the center of the two-phase fluid flow; and at least one peripheral temperature sensor mounted on the annular sensor mount such that the at least one peripheral temperature sensor is in direct thermal communication with a peripheral region of the circular opening for measuring temperature at the periphery of the two-phase fluid flow.
