ABSTRACT:
A liquid level sender device for measuring a level of a liquid in a tank having a first wall and a bottom wall includes a bracket mounted to the first wall of the tank, a first potentiometer mounted on the bracket, a float arm movably connected to the bracket and cooperating with the first potentiometer to generate a first variable resistance which varies according to the position relationship between the bracket and the float arm, a float mounted on the float arm which moves according to the level of the liquid in the tank and moves the float arm accordingly, a second potentiometer mounted on the bracket, and a compensation arm biased against the bottom wall of the tank and movably connected to the bracket, where the compensation arm cooperates with the second potentiometer to generate a second variable resistance which varies according to the position relationship between the bracket and the compensation arm. The first and second variable resistances are electrically connected to generate an output resistance which corresponds to the level of the liquid in the tank.
