摘要： Embodiments of the present invention provide a phase separation float assembly, a phase separation detection system, and a method for detecting phase separation. One embodiment comprises a first float subassembly comprising a first float adapted for vertical travel along a fuel level probe shaft and a magnet. This embodiment also comprises a second float subassembly comprising a second float adapted for vertical travel along the shaft. The first float has a first density and the second float has a second density greater than the first density. The second float subassembly further comprises at least one stop feature which engages the first float subassembly when the first float subassembly travels vertically a predetermined distance along the fuel level probe shaft. The first float density is selected such that the first float subassembly travels vertically along the shaft to engage the at least one stop feature in the presence of phase separation.

摘要： A pumping apparatus comprises a rotatable shaft coupled to a motor. At least one control structure is mounted on the shaft, and at least one impeller is carried by the shaft. The impeller is adapted to rotate independently of the shaft so as to pump a fluid. The apparatus also comprises a magnetic coupling between the control structure and the impeller. Further, the impeller is adapted to translate axially along the shaft in response to a change in downstream pressure to alter the strength of the magnetic coupling.
