| titleOfInvention | Apparatus for detecting water leakage |
| abstract | PURPOSE:To detect water leakage at an early stage in high reliability, by deciding the presence of water leakage by calculating whether the total number of times of the change ratio in hydrogen concn. exceeding a set change ratio are a set ratio or more. CONSTITUTION:The output 14 of hydrogen concn. due to reaction of metal Na and water calculated by a vacuum meter is taken n-times at a constant cycle within a predetermined time DELTAT by a hydrogen concn. calculation circuit 18 and the average concn. C1-Cn during the time DELTAT. The change ratio C1-Cn of the hydrogen concn. at a predetermined time interval aDELTAT by a hydrogen concn. change ratio calculation circuit 19. A water leakage decision circuit 20 decides whether the hydrogen conc. change ratio C1-Cn exceeds a set change ratio or not and the water leakage is decided by calculating whether the total number of times exceeding the set change ratio within a predetermined time are a set ratio or more. By this method, water leakage is detected at an early stage in high reliability. |
