Provided is a sensing device used for sensing the level of the liquid in a liquid storage system. The sensing device according to the invention is a non contact type and uses a float comprising a sensing device and a magnet. According to the level of liquid, the float assembly moves upwards or downwards and creates variation in air gap between the sensing element and a ferromagnetic member thereby obtaining output variations which is used to update the level of the fluid in the liquid storage from time to time. |
