Apparatus for determining characteristics and for stabilizing and conditioning fluid flow and processes for stabilizing and conditioning fluid flow and for measuring the mass of a fluid flowing through a conduit
Highly reliable measurements of the fluid and/or fluid flow in a conduit are obtained by insertion within the conduit, upstream of a fluid measuring or sampling device, of a fluid flow straigntening and displacement apparatus which serves to stabilize, homogenize and condition the fluid flow and form at the device a uniform, axially centered, axially symmetrical, well defined and accurately measurable flow profile of large means flow diameter. The flow straightening and fluid displacement apparatus comprises, in sequence in the direction of fluid flow, a first swirl mitigating and flow straightening device, a fluid displacement member comprised of two oppositely facing frustums jointed at their larger ends and mounted coaxially within the conduit, and a second flow straightening device. Advantageous combinations of the flow straightening and fluid displacement apparatus with known measuring and sampling devices are provided.
