Abstract
This invention discloses an apparatus and method of determining the temperature of the core of an inductive coil sensor so that the effective inductance of the coil sensor can be temperature compensated to thereby provide an accurate measure of the level of fuel in a tank. The method comprises energizing the sensor with a prescribed voltage, de-energizing the sensor, measuring the resultant voltage across the sensor, and determining the core temperature from the measured resultant voltage across the sensor.
