摘要： A gas supply facility includes a plurality of pressure type flow controllers connected in parallel, and a first controller to control operation of the plurality of pressure type flow controllers so as to supply a desired gas exhausted by a vacuum pump to a chamber while controlling its flow rate, one of the pressure type flow controllers operates as a second controller to control the gas flow rate range up to 10% of the maximum flow rate supplied to the chamber, while the remaining pressure type flow controllers are made to be ones that control the rest of the gas flow rate range. Furthermore, pressure inside the chamber is controlled by installing a pressure detector in the chamber, inputting the value detected by the detector to the controller, and by adjusting a control signal to the pressure type flow controllers.

摘要： A fluid flow rate control method is provided that uses a flow rate range variable type pressure type flow rate control device provided with at least two or more parallel fluid passages disposed between the downstream side of a control valve of the control device and a fluid supply pipe passage, and orifices having different fluid flow rate characteristics are respectively interposed in parallel fluid passages to pass fluid in a first flow rate region through one orifice for flow rate control, and to pass fluid in a second flow rate region through at least another orifice for flow rate control. Flow rate characteristics of the respective orifices are selected so that a maximum controllable flow rate of fluid in the first flow rate region at low flow rate is smaller than 10% of a maximum controllable flow rate in the second flow rate region at high flow rate.
