An apparatus, system, and method are disclosed for differential pressure measurement across a fluid conduit flow area change. The apparatus may include a particulate filter, a differential pressure sensor, and a fluid conduit size change downstream of the particulate filter. The apparatus may include a tube configured to place the downstream differential pressure sensor port in fluid contact with a uniform flow region of the fluid conduit downstream of the particulate filter. An apparatus is thereby provided to measure differential pressure across a fluid conduit flow area change such that the differential pressure measurement is minimally affected by the change in flow characteristics induced by the change in cross-sectional flow area.

Connector tubing is provided by a pair of nested corrugated spiral flex tubes twistable relative to each other about an axis at a flex tube joint to provide torsion relief.
