The present invention relates to a water level detecting sensor for measuring a water level, by installing a float in a post pipe formed on an upper end of a controller, comprising a guide pipe additionally installed parallel along the post pipe; and a float cage as a cylindrical case formed by unifying two symmetric semi-cylinders made of screen plate materials, in which, at the time of installing a cylinder, a central semicircle groove for allowing the post pipe to be penetrated, and a lateral semicircle groove for allowing the guide pipe to be penetrated, are formed on both ends of the semi-cylinder, and, in which the float is placed in the semi-cylinder, the central semicircle groove is inserted into the post pipe, the lateral semicircle is inserted into the guide pipe, and then, the semi-cylinders are unified to assemble the cylinder. According to the present invention, a damage of a float portion for directly measuring a level is prevented to increase life stability, and a noise in the water level is prevented to increase measurement accuracy. |
