るボイラー用水位制御装置。[Scope of Claim for Utility Model Registration] The boiler 1 is equipped with a water level detector 2 for detecting the water level in the can, and the water supply is controlled based on the signal from the water level detector to maintain the water level in the can within a predetermined control range. A water level control device that controls ON/OFF of the pump 3 includes a pressure detector 4 for detecting the pressure inside the can of the boiler 1, a can water concentration detector 5 for detecting the concentration of water inside the can, A feed water temperature detector 6 is provided for detecting the temperature of water supplied into the can, and a comparator 7 is provided for determining an optimum water level control range based on signals from these detectors. Turn on the water supply pump 3 to maintain it within the control range.
A water level control device for a boiler, comprising a controller 8 that performs OFF control.
