Temperature compensation system and method

摘要

A cooling system includes a cooling loop that includes a reservoir. The reservoir has a level sensor that is configured to provide a level signal indicative of a coolant level within the reservoir. A temperature sensor is in communication with the cooling loop and is configured to provide a temperature signal. A controller is in communication with the level sensor and the temperature sensor. The controller has a coolant density data. The controller is configured to correct the level signal based upon the temperature signal and detect a leakage condition of the cooling system. A method of determining a coolant amount within a cooling system includes the steps of determining an amount of coolant having a temperature-variable density, determining a coolant temperature, correcting the coolant amount based upon the coolant temperature, and comparing the corrected coolant amount to a desired coolant amount to detect a coolant leakage condition.
