ABSTRACT:
A device is disclosed for measuring the mass and velocity of a fluid flowing in a conduit, in a flow direction, which comprises a pair of signal transducer arrays each disposed at planes extending through the conduit and spaced in the flow direction. Each transducer of each array is adapted to transmit a signal and receive all signals of all other transducers so that a variety of signal paths are established through the flow both transversely to the flow and in the flow direction. Differences in transit times between arrays are used to measure velocity and attenuation of the signal within an array are used to determine density. The density and velocity measurements are combined to determine mass flow.
