VERIFIEDCorrelating Noise Logger (radio)
Radio-based correlating noise logger and long-standing flagship of the ZONESCAN fixed network family. Loggers record synchronised night-time noise and correlate in pairs for precise leak pinpointing; data is collected via repeater network or drive-by. Deployed at scale in projects such as the 5,500-logger AMI-integrated network in Grand Lyon, France that helped reduce NRW from 21% to below 15%.
