摘要：PURPOSE:To return a water level to a set range precisely and stably, by varying the time of return control according to variation in water volume control time. CONSTITUTION:A water level controller 5 consists of a detector 7 for the water level in a water storage part 2, the 1st controller 8 which performs intermittent control over a water volume regulator 4 by a pulse signal on the basis of water level information showing that the water level goes beyond the set range, and the 2nd controller 9 which performs the return control over the water volume regulator 4. The water level detector 7 is provided with a water level setter 10 for varying and setting a detection range. Then, information from a float type water level detector 11 is inputted to a decision device 12 through the setter 10 to decide on the water level.
