Summary:The utility model relates to a contact type water level measuring device which comprises a shell and a circuit board, the circuit board comprises a circuit board body, a contact and an adhesive layer, and the circuit board body is in a long strip shape. The contacts are arranged on one surface of the circuit board body, and the plurality of contacts are uniformly arranged along the length direction of the circuit board body. The adhesive layer is coated on the surface of the circuit board body, and the contacts penetrate through the adhesive layer. As the surface of the circuit board is coated with a layer of epoxy resin glue, the circuit board and the electronic elements are tightly wrapped, only the stainless steel contacts on the back surface of the circuit board are exposed, and the circuit board is prevented from being damaged possibly due to long-term soaking in water. The circuit board is installed in the shell, silica gel is filled between the shell and the circuit board, sealing treatment is conducte
