Overnight monitoring for intermittent and night-flow leaks.
Some leaks only appear at high system pressure overnight, or pulse intermittently in ways daytime listening misses. Acoustic noise loggers attached to hydrants and fittings record the noise level continuously, identifying the precise hours and locations of consistent leak signature. We deploy these in patrol surveys across utility networks and on large commercial estates. The output is a heat-map and time-series view of where the network is acoustically alive — a leading indicator of unaccounted-for water.
