11. A system comprising:
-
a vessel that comprises; a top portion that defines a top aperture; a bottom portion that defines a bottom aperture; a side wall coupled between the top portion and the bottom portion; and an interior volume defined by the top portion, bottom portion, and the side wall; a torque meter comprising a rotatable shaft, a first end of the rotatable shaft protruding through the top aperture, and a second end of the rotatable shaft protruding through the bottom aperture; a first seal coupled between the first end of the rotatable shaft and the top aperture; a second seal coupled between the second end of the rotatable shaft and the bottom aperture; an aperture through the vessel through which electrical conductors protrude, the electrical conductors coupled to the torque meter; and an aperture through the vessel through which a pressurizing fluid flows into the interior volume. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A system comprising:
-
a water pump that defines a rotatable pump shaft and a stationary pump housing, the water pump submersed in water, and the pump shaft in a substantially vertical orientation; an electric motor that defines a rotatable motor shaft and a stationary motor housing, the rotatable motor shaft coupled to the rotatable pump shaft, the electric motor submerged in the water below the water pump, and the rotatable motor shaft in a substantially vertical orientation; a torque meter at least partially disposed within a sealed vessel, the vessel submersed in the water, and the torque meter comprising; a rotatable torque meter shaft; a first end of the torque meter shaft protrudes from the vessel and is coupled to the pump shaft; and a second end of the torque meter shaft protrudes from the vessel and is coupled to the motor shaft such that torque provided by the electric motor is coupled to the pump shaft through the torque meter; wherein the vessel is coupled between the stationary pump housing and the stationary motor housing. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
