Abstract

See full text

Ultrasound tomography arrays and vortex shedding devices are provided which measure average flow velocity through Doppler shift of the fluid as well as cross sectional multiphase fluid composition in pipe or tubing conduits. Multiple tomographic arrays in conjunction with correlation of sensed flow patterns in time provided determination of flow velocity as well as cross sectional multiphase fluid composition. The tomographic arrays may be arranged in a skewed or slanted plane to measure velocity fluctuations downstream of a vortex shedding device where the period and amplitude of the fluctuations is correlated with the mass flow of the fluid. Additionally, the tomographic arrays provide the relative composition of the multiphase fluid. The multiple arrays together with correlation to determine velocity fluctuations downstream of a vortex shedding device where the period and amplitude of the fluctuations is correlated with the mass flow of the fluid. Additionally the tomographic arrays output the relative composition of the multiphase fluid.
