Abstract
A concentration detector is disclosed, which is adapted to detect a concentration of a liquid fuel in a container. The concentration detector includes a rotating means positioned underneath a level of a liquid fuel and rotatable at an angle θ on a X-Y plane. The rotating means includes at least three floating objects connected with each other. Each floating object has a specific gravity less than a specific gravity of the liquid fuel ρ. The floating objects are balanced according to a torque equation, F(θ,ρ)=0, such that the rotating means is still under the level of the liquid fuel. While a concentration of the liquid fuel is changed and the angle θ of the rotating means is detected, the specific gravity of the liquid fuel ρ is obtained from the torque equation, F(θ,ρ)=0, and thereby computing the concentration of the liquid fuel.
