With conventional float-type fuel level sensors, measurement errors when the vehicle is on an incline or going around corners. Now, a highly-accurate measuring system employing an electrostatic capacity sensor is developed for practical application. This sensor is composed of multiple electrode plates formed along a allows accurate measurement of remaining fuel even in tanks of irregular shapes. Also, since this sensor comes a unit, it is easier to replace. The system furthermore, employs software provided with averaging, memory storage, and permittivity correction functions in order to eliminate the effects of fuel level fluctuations and pressure changes within the tank during driving along with the effect of fuels with different permittivity.
