Abstract
Apparatus for the measurement of fluid flow, particularly flow rates for compressible fluids, comprises at least four transducer sources of ultrasonic energy arranged in fluid conduit system and adapted to project a beam of ultrasonic sound to corresponding receivers, the paths defined by the beams being angularly disposed with regard to both the fluid flow and each other, and being arranged in an intersecting but spaced-apart relationship.
