Claims

[Scope of utility model registration request]

In a system in which fluid in a delivery tank is transferred to the next process via a plurality of parallel-connected transfer pipes each having a filter inserted therein, the operating output of the level controller of the delivery tank is set as a first cascade setting value, and the above-mentioned Total flow rate controller means for controlling and calculating the deviation between the total flow rate of each transfer pipe line and the measured value, and the operation output of this total flow rate controller means is commonly received as a second cascade setting value, A parallel-connected filter control device comprising a plurality of transfer pipe flow rate controller means for operating a flow rate control valve inserted in each transfer pipe using an operation output obtained by controlling and calculating a deviation from a flow rate measurement value.
