LNL-1 is an acoustic data logger system designed for detecting and monitoring leaks 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” at the points on the pipeline.
  • Analyser, the recorded data are downloaded via radio communication by the analyser. The Analyser shows 3 levels of leak possibilities at given thresholds.
  • 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.
