Description
LNL-1 is an acoustic data logger system designed for detecting and monitoring leakage on water pipelines.
- Loggers, equipped with high sensitivity sensors are deployed on pipe fittings such as valves, fire hydrants. The loggers record “minimum noise level Eat the points on the pipeline.
- 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 software identifies each logger and visualizes it on the map. The results of Minimum Noise Level are indicated in each area or blocks. The results are displayed as graph. Momentary change of sound is also displayed.
