ABSTRACT:
A temperature compensated, self-heating, resistance thermal detector in a sensor circuit for determining fluid level or fluid flow. A resistor in shunt with the detector provides the temperature compensation. The resistor and the thermal detector are connected between electrical input and output lines. Alternative embodiments include a speed enhancing lead network and a fully automated circuit under microprocessor control.
