Liquid level sender device

摘要

A liquid level sender device 14 is mounted in the fuel tank 10 of a motor vehicle, and has a float 20 at an end of a float arm 22 and a contact 28 which travels along a first electrical resistance track 30. The device also has a foot 25 at an end of a compensation arm 24 biassed to rest against the tank bottom and a contact 29 which travels along a second electrical resistance track 32. The electrical resistances of each track 30 and 32 correspond to the positions of the respective arms 22 and 24 and are connected electrically in parallel, so that the compensation arm 24 corrects the indicated volume of fuel 33 having regard to changes in the position of the bottom wall 26 of the fuel tank 10. <IMAGE>
