Abstract

PURPOSE: To enable excellent selection, by commonly using the cascade type regulator and continuously using the output, so that the operating end can not be disturbed in the selection between the flow control loop and the opening control loop.
CONSTITUTION: In the flow and opening control unit by use with the telemeter TM, the selection circuit is selected to the position b in case of flow control, and the flow set value is used as the operation measurement input em of the cascade type regulator FIC. In case of opening control, the selection circuit is selected to the position a, the value eo being the result of operation of the cascade type regulator is fed back, and the input set value of cascade and the output eo of regulator can be kept to an equal value at all times with the equilibrium state. Thus, the flow set value can be the opening set value as it is, the regulator FIC can commonly be used and the output can continuously be used, allowing to avoid the disturbance of the operating terminal in case of selection between the flow and opening control loops and to perform selection in excellent manner.
