  • Patent number: 7997149
    Abstract: A method and apparatus for measuring the sound velocity of a flowing fluid includes a cartridge having a hollow interior through which the fluid flows formed by first and second chambers of different diameters that define first and second walls extending toward the cartridge longitudinal axis from which energy transmitted by a single sensor mounted in the cartridge is reflected back to the sensor. An electronic circuit includes a microprocessor that is programmed with the distance between the first and second walls and that measures the round-trip transit time of the signal energy transmitted to and reflected from each of the first and second walls and calculates the sound velocity of flowing fluid using the two measured round trip transit times and the programmed value of the fixed distance between the walls.
