Abstract: A flow angle probe is provided having (a) a probe flap for contacting a moving fluid within a fluid conduit; (b) a probe body mechanically coupled to the probe flap; (c) a force sensor disposed within the probe body and operationally coupled to the probe flap; and optionally (d) a probe shaft coupled to the probe body. A deflection of the probe flap caused by contact with the moving fluid produces a corresponding force sensor signal output which is minimized by rotation of the probe flap. The angle between this point of minimum deflection and a reference position is taken to be the flow angle of the moving fluid in the vicinity of the probe flap. The novel flow angle probes disclosed herein may be used in a wide variety of turbomachines and fluid processing systems, and applications, including turbomachine design and operational control, and in flow assurance.

Abstract: 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.

Abstract: A flow angle probe is provided comprising: (a) a probe vane configured to contact a moving fluid within a fluid conduit; (b) an optional probe mounting mechanically coupled to the probe vane; (c) a rotary shaft coupled either to the optional probe mounting or the probe vane; (d) a rotary encoder coupled to the rotary shaft; (e) a sensor hermetically isolated from the probe vane and configured to sense a change in position of the rotary encoder; and (f) a probe housing encompassing at least a portion of the rotary shaft, the rotary encoder and the sensor. The novel flow angle probes disclosed herein may be used in a wide variety of turbomachines and fluid processing systems, and applications, including turbomachine design and operational control, as well as in flow assurance.
