Abstract
A new method for measuring the volumetric flow rate of each phase for two-phase, air and water, flowing upwardly in a vertical tube is developed. This noble device, a Two Turbine Flow Meter System (TTFMS), is composed of two turbine flow meters, a valve, two thermocouples, and two pressure transducers. For a given twophase flow, the rate of rotation of the turbine flow meter is found to depend only upon the volumetric flow rates of gas and liquid at the point of measurement. A calibration model is developed for the turbine flow meter, which provides a simple, general, and accurate relationship between the output signal of a turbine flow meter and the actual two-phase flow rate. The volumetric flow rate of each of the two phases is determined by this model. TTFMS is a simple, durable, and inexpensive two-phase flow measuring device that does not require physical separation of a phase from the two-phase mixture.
