Beschreibung
Zusammenfassung:	A fluid control device 10 comprises a valve device V2 including actuators 22 and 24 for opening and closing a flow path and adjusting a flow rate of a fluid flowing through the flow path, a pressure sensor PT provided upstream of the valve device V2, and a control circuit 12 connected to the valve device V2 and the pressure sensor PT, and the control circuit 12 controls an operation of the actuator based on a pressure measured by the pressure sensor PT and a reference pressure drop curve, while the upstream side of the fluid control device is closed and the valve device is opened using the actuators.
