Gas sub-metering for boilers, kitchens and tenants
Aqueduct reads pulse, camera and bridged Modbus or M-Bus gas meters and reports in cubic feet, CCF, therms or cubic meters, with hourly flow. Each boiler, kitchen or tenant can carry its own meter.
Measure gas where it burns, and judge heating against the weather it ran in.
The loads worth their own meter
- Service entrance
Total consumption and the base for bill validation.
- Boilers and water heaters
The largest loads, where a fault first shows as excess burn.
- Kitchens and tenants
Cooking and tenant use separated from space heating.
What the readings let a team decide
- Boiler inspection
A boiler burning more than its degree day baseline is sent for a check.
- Out of hours burn
Gas use in an empty building is raised as waste.
- Fair allocation
Each tenant pays for measured use instead of a floor area split.
Meter types, readings and connection
| Device | Reading | Connection |
|---|---|---|
| Pulse output meter | Volume from the pulse constant, in ft3, CCF, therms or m3, with flow per hour. | LoRaWAN pulse counter. |
| Camera meter reader | The index on an existing meter face, read by computer vision. | Images to the cloud. |
| Modbus or M-Bus meter | Volume and the meter registers. | Bridge to LoRaWAN. |

Common questions
It can show unexplained consumption, such as burn in an empty building. Aqueduct is not a safety device, so gas detectors and the site safety plan stay in place. See aQ EnergySmart.
Heating load follows outdoor temperature, so Aqueduct compares a cold month against its heating degree days before calling it waste. A boiler burning above that baseline is flagged for inspection. See weather-normalized baselining.
Aqueduct reads pulse output gas meters, camera reads of older dials, and Modbus or M-Bus meters through a bridge. Volume and energy content are both available for each meter. See pulse counters.
Start with boilers and water heaters, the largest loads, then kitchens and tenants. With cooking split out, the boiler meter reflects heating alone, so its degree day comparison in Aqueduct is fair. See utility bill validation.
