Abstract
A method for detecting a leak in a closed-volume liquid system comprises circulating a fluid through a closed-loop with a pump having a reservoir and that is driven by an electric motor. The method also comprises sensing a pressure in the closed-loop, sensing current draw by the motor and sensing fluid level in the reservoir. The method further comprises determining a presence of a leak of fluid from the closed-loop based upon two of the sensed signals using a first leak detection logic, and determining the presence of a leak of fluid from the closed-loop based upon at least one of the sensed signals using a second leak detection logic.
