Abstract

PURPOSE: To obtain stable fluid without overshooting and also to perform a process of high quality in safety by resetting a shutoff method after setting the flow of a flow controller to zero and then by setting the flow of fluid to a desired value.
CONSTITUTION: A flow value external controller 11 has commanded is set to register 14 and converted by digital-analog converter 15 into a voltage, which is inputted to comparator 16. The quantity of flowing fluid at that time, on the other hand, is measured by detector 12, amplified by amplifier 13 and compared with the above-mentioned value by conparator 16, thereby driving control valve 5 via driver circuit 17. In the beginning, a flow value of "O" is set to register 14 and valve 2 is open. Setting is repeated so as to increase the set value of register 14 gradually up to the desired value, so that the fluid will increase in the quantity of the flow at an extremely-slow speed, causing no overshoot. The stable process can therefore be performed in safety.
