摘要： An apparatus 10 is provided that measures the Speed of sound propagating in a multiphase mixture to determine parameters, such as mixture quality, particle size, vapor/mass ratio, liquid/vapor ratio, mass flow rate, enthalpy and volumetric flow rate of the flow in a pipe or unconfined space, for example, using acoustic and/or dynamic pressures. The apparatus includes a pair of ultrasonic transducers disposed axially along the pipe for measuring the transit time of an ultrasonic signal to propagate from one ultrasonic transducer to the other ultrasonic transducer. A signal process, responsive to said transit time signal, provides a signal representative of the speed of sound of the mixture. An SOS processing unit then provides an output signal indicative of at least one Parameter of the mixture flowing through the pipe. The frequency of the ultrasonic signal is sufficiently low to minimize scatter from particle/liquid within the mixture. The frequency based sound speed is determined utilizing a dispersion model to determine the at least one parameter of the fluid flow and/or mixture.

摘要： An apparatus and method for measuring the flow velocity of a fluid flowing through a pipe that includes an array of at least two ultrasonic sensor units (with as many as 16 sensor units) disposed at predetermined locations along the pipe. Each sensor unit includes an ultrasonic transmitter and an ultrasonic receiver. Each sensor unit provides a respective signal indicative of a parameter of the transit time or amplitude of the ultrasonic signal propagating between each respective ultrasonic transmitter and ultrasonic receiver. A signal processor defines a convective ridge in the k-ω plane in response to the ultrasonic signals using an adaptive beamforming algorithm, such as Capon and Music. The signal processor further determines the slope of at least a portion of the convective ridge to determine the flow velocity of the fluid.

摘要： A apparatus (10, 110, 170) is provided that measures the speed of sound and/or vortical disturbances propagating in a single phase fluid flow and/or multiphase mixture to determine parameters, such as mixture quality, particle size, vapor/mass ratio, liquid/vapor ratio, mass flow rate, enthalpy and volumetric flow rate of the flow in a pipe, by measuring acoustic and/or dynamic pressures. The apparatus includes a spatial array of unsteady pressure sensors (15-18) placed at predetermined axial locations x 1 - x N disposed axially along the pipe (14). The pressure sensors (15-18) provide acoustic pressure signals P 1 (t) - P N (t) to a signal processing unit (30) which determines the speed of sound a mix propagating through of the process flow (12) flowing in the pipe (14). The pressure sensors are piezoelectric film sensors that are mounted or clamped onto the outer surface of the pipe at the respective axial location.
