。 In a feed water heater that heats the feed water to a steam generator by heat exchange with steam, the water level of the steam condensate drain in the feed water heater is determined by the flow rate provided in each of multiple drain discharge pipes with different drain destinations. In a feedwater heater water level control device controlled by a control valve, a water level detector, a drain pressure detector, and a temperature detector are provided at the drain outlet of the feedwater heater, and the A water level controller is provided that calculates the opening degree of the flow rate regulating valve, and this water level controller calculates the opening of the preceding valve based on the deviation signal between the output signal from the water level detector and a preset standard water level and high water level signal. The void ratio at the drain outlet of the feed water heater is calculated based on the output signals from the drain pressure detector and the temperature sensor, and the void ratio is calculated based on the required valve opening function. A feed water heater water level control device comprising: an additional signal generating section that outputs an additional signal for valve opening degree correction to the preceding signal generating section.
