SePem® 351 Noise Logger
The SePem® 351 noise logger monitors your water distribution networks. Aiming to reduce water losses, it transmits measurement data via LoRaWAN®.
The SePem® 351 logger is specifically designed for fixed installation. It measures noises in the pipeline network at scheduled intervals. After measurement, the recorded data is evaluated and prepared for transmission.
The logger must be registered with a LoRaWAN® network to enable the measurement data to be sent later to a water utility's control panel. A network information system is required to visualize the results.
Measurement values are transmitted daily by each SePem® 351, allowing new leaks to be detected within a few hours. Utilizing existing LoRaWAN® networks ensures optimal connectivity for the applied technologies.
