摘要：The present invention provides a concentration detection device, which is usedto detect the concentration of liquid fuel within a container. The device comprises: a float,
which is floating on the surface of liquid fuel, wherein the upper portion of the float has afigure of a first reference circle, and the float is just formed as a figure of a firstintersection circle on the surface of liquid fuel; an image capture device with an imagingplane, wherein the imaging plane is configured upon the float; a sunshade, wherein thesunshade is configured between the imaging plane and the float, and the sunshade isconfigured with a hole, so the figures of the first reference circle and the first intersectioncircle could be respectively projected onto the imaging plane through the hole to form asecond reference circle and a second intersection circle; a calculation device, which couldcalculate the concentration of the liquid fuel according to the first and second referencecircles and the first and second intersection circles.
