Abstract

PURPOSE:To obtain the smooth switchover between operations of an electric governer and a water level regulator by selecting a lower output with priority between outputs of the water level regulator and the electric governer by means of a signal selector. CONSTITUTION:For the operation of water level regulation, the output of an electric governer 7 is used for the signal of full opening operation of a servo motor 10, and a water wheel 11 is operated by the output of a water level regulator 4 through a signal selector 13 which gives priority to a closing signal. For switching over from the operation of water level regulation to the operation of the electric governer, the operation of the electric governer is selected by a switch 5. By this operation, the output of the electric governer is gradually reduced from the signal of full closing operation by means of a signal agreement detector 15 until it is accorded with the output of the water level regulator. Meanwhile, the output of the water level regulator is brought to a little more opening direction than the opening of the servo motor by a limiter 14 without reference to the water level of a tank for obtaining the operation of the electric governer.
