ABSTRACT:
A liquid level sensor comprising a thermistor probe and a power source connected to the thermistor probe to heat the thermistor probe. A cover encases the thermistor probe and includes openings allowing liquid to enter and exit an interior of the cover and contact the thermistor probe. A detector detects a liquid level in response to a voltage at the thermistor probe.
