Abstract

PURPOSE: To convey liquid in its proper flow rate to any branch pipes in such a way that gate valves are provided on all the branch pipes and the number of rotation of a conveying pump is controlled by opening degree signals from these valves.
CONSTITUTION: With gate valves 14, 15, 16 provided on all the branch pipes 5, 6, 7, valve opening degree signals from the gate valves 14, 15, 16 are input through signal lines 22, 23, 24 to a controller 21, a processing flow passage is judged in the controller 21, proper flow rate values in processors 8, 9, 10 are output to a rotation number controller 19, and the number of rotation in a conveying pump 3 is controlled. Thus, even in case where they are used by changing over the branch pipes which are different in the conditions of flow passage resistances and proper processing flow rates, etc., proper flow rates of liquid can be conveyed into the branch pipes.
