  • Oil flow sensing
    Patent number: 7000466
    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.
    Type: Grant
    Filed: August 4, 2004
    Date of Patent: February 21, 2006
    Assignee: Ark-Les Corporation
    Inventors: Eric K. Larson, Robert F. Kellicker
