摘要： A liquid level sensing system including a housing configured to hold a liquid, a first temperature sensor connected to the housing and configured to output a first signal representing a first temperature measured at the first temperature sensor, a second temperature sensor connected to the housing and configured to output a second signal representing a second temperature measured at the second temperature sensor, and a circuit configured to receive the first and second signals as input and to provide an output signal proportional to the time rate of change of the difference between the first signal and the second signal.
