Leak detection for water networks

Permanent AI-based logger installed on valves and hydrants. Every night neighbouring loggers listen together and correlate, and the cloud reports each leak position to within about a metre — no site visits needed. Successor to ZONESCAN NB-IoT, with more than 50,000 loggers installed.

Radio noise loggers read with the ZONESCAN SMART app on a phone or tablet. Use them "lift & shift" to survey one zone after another, or "drive-by" for periodic monitoring. Correlation between loggers is about 30 times more sensitive than plain noise logging.
