Abstract
Abnormalities such as operational malfunction and seat leakage of valves assembled in a fluid supply system using a flow rate control device can be simply, quickly, and accurately checked without removing them from a pile line of the fluid supply system with the use of a function of the flow rate control device having a pressure sensor. In the fluid supply system having the flow rate control device provided with the pressure sensor that has a flow rate setting mechanism, and a flow rate/pressure display mechanism and/or a flow rate self-diagnosis mechanism, an abnormality of the flow rate control device and a control device on the upstream side or downstream side of the flow rate control device is detected using a pressure display value of the flow rate control device and/or a diagnosis value of the flow rate self-diagnosis mechanism.
