Abstract
An electrical current is passed through a thermistor to raise its temperature above the temperature of oil flowing in pulses past the thermistor. A change is measured in the temperature of the thermistor occurring with respect to one or more of the pulses. A level of oil flow is determined corresponding to the measured change in temperature. A signal is issued based on the determined flow level.
