Quensus flow-based devices accommodate pipe sizes up to 8″, so a single monitoring approach can cover mains supplies across commercial, industrial, and multi-occupancy buildings without forcing a downgrade in measurement quality.
Why it matters: estates often mix pipe diameters between plant rooms, risers, and tenant supplies. A platform that scales with pipe size reduces bespoke engineering, speeds specification, and keeps leak thresholds meaningful on high-volume lines where small percentage losses still mean large volumes of water.
Available on LeakNet Gen2, LeakNet Gen1, Flow Sensors & Meters, LeakNet LP Data Logger, SiteNet for Construction, and Valves. The same capability supports everything from permanent building installs to temporary site protection.
Quensus devices integrate with existing Building Management Systems (BMS), feeding alarms and status into the platform facilities teams already monitor.
Why it matters: duplicate dashboards get ignored. BMS integration puts water events alongside HVAC, access, and fire signals, improving escalation paths and supporting estates that require centralised alarm management, even when cloud connectivity is limited.
Supported on LeakNet Gen2, Flow Sensors & Meters, SiteNet for Construction, and Valves.
Flow-based leak detection identifies abnormal usage and can automatically shut off the water supply to contain damage.
Why it matters: the cost of escape-of-water claims is driven by duration, not just volume. Automatic shut-off turns a potentially catastrophic overnight leak into a contained event, protecting stock, finishes, and neighbouring units while insurers and FM teams regain control.
Core to LeakNet Gen2, LeakNet Gen1, Flow Sensors & Meters, and Valves when paired with Quensus monitoring.
Valves can be opened or closed remotely through FlowReporter, giving authorised users control without a site visit.
Why it matters: when a leak is confirmed out of hours, minutes matter. Remote isolation limits damage, avoids waiting for a plumber to reach site, and supports planned maintenance such as pre-freeze shut-offs or temporary isolation during void periods.
Supported on LeakNet Gen2, LeakNet Gen1, and Valves within the Quensus ecosystem.
