APPARATUS, SYSTEM, AND METHOD FOR DIFFERENTIAL PRESSURE MEASUREMENT ACROSS A CONDUIT FLOW AREA CHANGE

摘要

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 106, a differential pressure sensor 120, and a fluid conduit size change 102, 104, downstream of the particulate filter 106. The apparatus may include a tube 118 configured to place the downstream differential pressure sensor 120 port in fluid contact with a uniform flow region 116 of the fluid conduit 104 downstream of the particulate filter 106. 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.
