制御される。The flow rate of pipe B is determined by valve (11), operating mechanism (country, controller +1).
31, and the target value is given to the flow of the pipe O by decreasing the value of 4 to 4 through the ratio setting device α. At this time, the flow rate of conduit B is controlled to be equal to the flow rate of conduit C.
