摘要：A device for electrical measurement of the level of a fluid contained in a fueltank of a motor vehicle is disclosed. In addition to a variable resistance float sensor in adip tube, a travel sensor is arranged in the dip tube to determine the distance betweenthe dip tube and the bottom of the tank in order to offset measurement errors causedby tolerances in the manufacture of the tank and resultant differences in the mountingposition of the dip tube in the tank. The travel sensor includes a spring load rodextending to the bottom of the tank and a variable resistance connected to the rod toproduce a calibration value.
