LNL-1 is an acoustic data logger system designed for detecting and moniroring leakage on water pipelines.
LOGGERS, equipped with high sensitivity sensors are deployed on pipe fitting such as valves, fire hydrants. The loggers record "minimum noise level" at the points on the pipelne.
ANALYSER, the recorded data are downloaded by radio communication by the Analyser. And the Analyser shows 3 levels of leak possibilities at given thresholds.
SOFTWARE, the PC softaware identifies each logger and visualize it on the map. The results of Minimum Noise Level are indicated in each area or blocs. The results are displayed as graph. Momentary change of sound is also displayed.
