Abstract
A method of determining flowrates of individual constituent phases of a flowing multiphase medium includes digitizing electrical output signals from multiple sensors which produce signals in response to fluctuating high frequency hydrodynamic and physical property characteristics of the flowing medium. The nethod also includes deriving from the signals a plurality of stochastic features in amplitude and frequency domains such as a standard deviation, a coefficient of skewness, a coefficient of kurtosis, and linear prediction coefficients. Feature vectors are compared with a corresponding calibration map stored in a memory as a database relating feature vectors uniquely to flowrates of the component phases of the medium. Using a pattern recognition technique a unique match is determined as a measure of the flowrates of the component phases of the medium.
