摘要 |
<p>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. An amount of flow volume change responsive to an amount of pressure change of a predetermined level or more is classified into a plurality of ranges by means of a predetermined threshold value, and a following flow value change is determined on the basis of determination conditions of the respective ranges of amounts of flow volume changes.</p> |
