A concentration detector is adapted to detect the concentration of a liquid fuel in a container. The concentration detector comprises a rotating mechanism positioned underneath the level of the liquid fuel and having a rotational center. A first float having a specific gravity less than the specific gravity of the liquid fuel, a volume equivalent to 'V' and a mass equivalent to 'M'. The distance between the mass center of the first float and the rotational center is &#x201c;L&#x201d;. A second float connected with the first float and having a specific gravity less than the specific gravity of the liquid fuel, a volume equivalent to &#x201c;V&#x201d; and a mass equivalent to &#x201c;r*M&#x201d;. The distance between the mass center of the second float and the rotational center is &#x201c;L. The mass center of the second float, the rotational center and the mass center of the first float constitute an included angle of 120&#xb0;. A third float connected to the first float and the second float and having a specific gravity less than the specific gravity of the liquid fuel, a volume equivalent to &#x201c;V&#x201d; and a mass equivalent to &#x201c;r*M&#x201d;. The distance between the mass center of the third float and the rotational center is &#x201c;L. The mass center of the third float, the rotational center and the mass center of the second float constitute an included angle of 120&#xb0;. Thereby the variation in the concentration of the liquid fuel is acquired by inspecting the change in the rotational direction of the rotating mechanism.

Concentration detector

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 &#x3b8; 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 &#x3c1;. The floating objects are balanced according to a torque equation, F(&#x3b8;,&#x3c1;)=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 &#x3b8; of the rotating means is detected, the specific gravity of the liquid fuel &#x3c1; is obtained from the torque equation, F(&#x3b8;,&#x3c1;)=0, and thereby computing the concentration of the liquid fuel.
