A fluid transport system includes a housing defining a passageway for fluid to flow through the fluid transport system and a probe extending in the passageway. The probe includes a first end defining a plurality of sensing ports for the fluid to flow into the probe and a second end opposite the first end. The fluid flows through a plurality of conduits and a plurality of tubes. A differential pressure sensor is in fluid communication with the plurality of tubes such that the differential pressure sensor determines a differential pressure of the fluid in the plurality of tubes. A purge system is in fluid communication with the plurality of tubes. The purge system includes a source of purge liquid and is configured to direct the purge liquid through the plurality of tubes.
