1. A method comprising:
- coupling a torque meter between an electric motor and a pump;
submersing the torque meter, electric motor, and pump in water, and during periods of time when the torque meter, electric motor and pump are submerged in the water;
operating the pump and the electric motor;
providing a flow of fluid through the vessel, the fluid different than the water in which the vessel is submerged;
measuring pump performance; and
simultaneouslymeasuring electric motor performance.

16. 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; a fluid storage container disposed above a surface of the water, the fluid storage container defines an interior volume containing a fluid, and the interior volume fluidly coupled to an interior volume of the sealed vessel; a fluid level indicator in operational relationship to the fluid storage container, the fluid level indicator configured to indicate level of the fluid within the interior volume of the fluid storage container; and a fluid contamination indicator in operational relationship to the fluid storage container, the fluid contamination indicator configured to indicate invasion of water into the sealed vessel. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
