Abstract
Detecting a leak, or the like, with high accuracy on the basis of pressure and a flow volume acquired during use of fluid is made possible. A volume of gas flowing through a flow path 102 is measured by a flow volume measurement unit 106, and pressure is measured by a pressure measurement unit 108. Measured flow data and measured pressure data are input to an analysis unit 112, to thus analyze following of a pressure change by a flow volume change. A determination showing that a following flow volume change is present, that a following flow volume change is not present, or that a following flow volume change is uncertain is made according to a magnitude correlation between an amount of pressure change of a predetermined level or more and an amount of flow volume change.
