ABSTRACT:
A method is disclosed for determining the composition of a two-phase fluid, such as saturated steam. In that method, the transit times of sound are measured within the two-phase fluid, the speed of sound of the two-phase fluid is calculated from the measured transit times, and the composition of the two-phase fluid is calculated from the calculated speed of sound. From the calculated linear velocity and the calculated composition, one can calculate at least one fluid property of the two-phase fluid, such as mass flow rate or energy flow rate. All of these calculations can be performed by a microprocessor.
