Abstract:
1. An apparatus for measuring differential pressure, the apparatus comprising: a first elongate fluid conduit portion comprising a first minimum cross-sectional area perpendicular to an axis of the first elongate fluid conduit, and a second elongate fluid conduit portion comprising a second minimum cross-sectional area perpendicular to an axis of the second fluid conduit portion, wherein the first minimum cross-sectional area is different than the second minimum cross-sectional area; an aftertreatment component configured with a flow inlet and a flow outlet, wherein the flow inlet accepts flow from the first elongate fluid conduit portion, and wherein the flow outlet emits flow to the second elongate fluid conduit portion; a first sensor port fluidly connected to the first elongate fluid conduit portion; a coupler fluidly connecting a second sensor port to the second elongate fluid conduit at a uniform flow region.
