ABSTRACT:
An apparatus for determining the flow rate of a fluid in a pipe. The apparatus includes a device for providing acoustic energy on a diametrical path through the fluid. The diametrical providing device is in contact with the pipe. The apparatus also includes a signal processing device for determining the speed of sound of the fluid in the pipe based on the acoustic energy of the diagonal providing device and the acoustic energy of the diametrical providing device. A method for determining the sound velocity of a fluid in a pipe.
