Abstract
A two-wire type water level controller of the utility model comprises a pipe and a control-driven component arranged at one end in the pipe. Both ends in the pipe are provided with an upper water level spring-tube and a lower water level spring-tube. The outboard of the pipe and the corresponding position of the upper water level spring-tube and the lower water level spring-tube are also provided with an upper water level backstop device and a lower water level backstop device. A bob with a permanent magnet is arranged between the upper water level backstop device and the lower water level backstop device. The utility model makes the upper water level spring-tube or the lower water level spring-tube be turned on or turned off to detect the information of the water level by the floatation of the bob with the permanent magnet up and down. The control-driven component is directly connected with an alternating current contactor and drives the alternating current contactor to simplify the structure of the water level controller and the connection of the periphery up to the hilt. The two-wire type water level controller fully solves the problems that the installation of the common water level controller is difficult and complicated, the maintenance is difficult, the lifetime is short and the use is inconvenient.
