1. A fluid leak detection system, comprising:

  • a fluid conduit;

    a fluid-cooled device having an inlet and an outlet;

    an inlet flow meter fluidly connected to the fluid conduit, the inlet flow meter monitoring the inlet of the fluid-cooled device for an inlet temperature and an inlet flow rate, the inlet flow meter having an inlet flow meter drift versus process fluid temperature curve;

    an outlet flow meter fluidly connected to the fluid conduit, the outlet flow meter monitoring the outlet of the fluid-cooled device for an outlet temperature and an outlet flow rate, the outlet flow meter having an outlet flow meter drift versus process fluid temperature curve;

    a controller in communication with the inlet flow meter and the outlet flow meter, the controller including a memory having the inlet flow meter drift versus process fluid temperature curve and the outlet flow meter drift versus process fluid temperature curve stored therein, the inlet flow meter drift versus process fluid temperature curve substantially identical to the outlet flow meter drift versus process fluid temperature curve, and a zero flow condition where a fluid flow in the fluid conduit is substantially halted and values of the inlet flow rate and the outlet flow rate are saved in the memory of the controller, the controller including;

    a control logic for monitoring the inlet flow meter for the inlet temperature and the inlet flow rate and the outlet flow meter for the outlet temperature and the outlet flow rate;

    a control logic for determining the difference between the inlet temperature and the outlet temperature, the memory of the controller including a set of data stored therein that indicates a percentage of error in flow rate based on the difference between the inlet temperature and the outlet temperature;

    a control logic for determining the difference between the inlet flow rate and the outlet flow rate;

    a control logic for calculating an actual flow rate difference between the inlet flow rate and the outlet flow rate, the actual flow rate difference based on the percentage of error in flow rate, the difference between the inlet flow rate and the outlet flow rate, and the zero flow condition; and

    a control logic for indicating a leak condition in the fluid leak detection system if the actual flow rate difference is above a threshold value.
