ABSTRACT:
A flow rate verification failure diagnosis apparatus is applied to a gas supply pipe system including flow rate control devices and a flow rate verification unit for detecting flow rate abnormality by measuring flow rate of each of the flow rate control devices on the basis of pressure measured by a pressure measurement device. The flow rate verification failure diagnosis apparatus comprises a failure diagnosis device having a mode to diagnose a failure in the pressure measurement device at a time of the flow rate verification unit detecting the flow rate abnormality, thereby the reliability of flow rate verification can be enhanced.
