  • Rotary meter having flow conditioning chambers for pressure pulse reduction
    Patent number: 5970791
    Abstract: An improved rotary fluid meter is provided having expansion chambers for conditioning pressure pulses that may occur in the flow of fluids. The pressure pulses, which inhibit the meter's ability to accurately measure, may originate from within a metering device or from without it. The pressure pulses may be generated upstream of the meter. Fluid flows into the meter through a fluid flow conduit. At least one flow conditioning chamber which is of such a volume and a shape as to enable it to substantially dampen pressure pulses so as to improve the accuracy of the rotary meter is provided along the fluid flow conduit.
