Abstract
A system and method of sensing fluid in a wellbore, where fluid along a range of radial locations in the wellbore is diverted along a flow path that runs adjacent a fluid sensor. Diverting the fluid from the range of radial locations provides a representative sample of the fluid flowing in the wellbore. Further, the diverted fluid forms a continuous volumetric flow past the fluid sensor to avoid fluid stagnation adjacent the fluid sensor. Diverting the fluid flow can be accomplished by elongate diverter wings attached at discrete circumferential locations around an outer surface of a fluid sensor and that project at oblique angles to the direction of flow. Elongate members can be used for diverting flow, where the distal ends of the elongate members attach to a downhole tool, and vane members span across selected adjacent members for directing flow to the sensor.
