District Metering Areas (DMAs) let you monitor consumption across a water distribution network. In AquaCUE, such networks are defined by zones (see the sample diagram below). A zone is a collection of Supply meters and Demand meters. Supply meters measure water flowing into a zone. Demand meters measure water being consumed within a zone. In addition, Sewer meters measure non-revenue water (NRW), do not belong to zones, and are not included in flow consumption totals.
To enable this feature, contact your Badger Meter representative.
By measuring and comparing Supply meter and Demand meter consumption, you can calculate and identify:
- Total water use across the facility – the sum of consumption from all supply meters plus the consumption from all meters that do not belong to a zone. (Supply meter consumption totals do not include Demand meter totals, eliminating “double counting.”)
- Non-revenue water (NRW) – indicated when the sum of the supply meter consumption is greater than the sum of the demand meter consumption.
- Mis-sized meters – indicated when the sum of the supply meter consumption is less than the sum of the demand meter consumption.
When modeling DMA zones in AquaCUE, any given meter can:
- Belong to zero (0), one (1) or two (2) zones.
- Be either a Supply meter or a Demand meter in a given zone.
- Be a Supply meter in one zone and a Demand meter in another zone.
- Not belong to more than two zones.
- Supply meters cannot supply other Supply meters within a given zone.
- Demand meters cannot supply other Demand meters within a given zone.
If your DMA water distribution network uses daisy-chained zones, configure them as multiple zones.
