What is DMA (District Metered Area) and how does it help water utilities reduce leakage and non-revenue water?

DMA divides pipe networks into independent metering zones. Flowmeters + RTUs monitor Minimum Night Flow to rapidly pinpoint leaks. NRW drops 5-15%, per-point cost as low as 30-50% of traditional solutions.

DMA (District Metered Area) is a water network management strategy that divides the supply network into discrete monitoring zones. By precisely metering inflow and outflow at each zone boundary, utilities can rapidly locate leaks and proactively manage water loss.

How it works: Electromagnetic flowmeters are installed at DMA zone inlets/outlets. EC32 RTUs transmit real-time flow data to the cloud. The platform automatically calculates Minimum Night Flow (MNF) — when nighttime consumption spikes abnormally, a leak alert is triggered.

Benefits: 1) Leak localization shifts from "citywide blind search" to "targeted zone investigation" — 10x more efficient. 2) Non-Revenue Water (NRW) can drop 5-15 percentage points. 3) Per-point cost as low as 30-50% of conventional solutions using LGF flowmeter + EC32 RTU + NB-IoT direct-to-cloud.

Applications: Municipal water networks, industrial park supply, large campuses (universities/hospitals).
