The water network is responsible for providing the required water source for the power plant and ensuring the normal operation of the power plant equipment. The monitoring device is the key link to ensure the normal operation of the water network system of the power plant, and can timely discover and deal with potential problems of the water network. The existing water network monitoring device of the whole power plant is generally composed of a mounting seat, a pipeline monitoring mechanism, a mounting frame, and a sewage treatment system and a dosing system.
