LoRaWAN pulse counters and splitters for existing meters
A pulse counter reads the pulse output of an existing water, gas or electricity meter, where each pulse is a fixed quantity, and sends the count over LoRaWAN. A passive splitter lets the BMS keep the same signal.
Bring meters you already own online without replacing them.
Fitted at the meter, wired to its pulse output
- Water meters
Inline and ultrasonic meters with a volume pulse.
- Electricity meters
Revenue and check meters with a kWh pulse.
- Gas meters
Diaphragm and rotary meters with a volume pulse.
What interval data makes possible
- Baselines
Monthly manual reads become interval data for weather-normalized baselines.
- Bill checks
Metered use is compared with billed use before the invoice is paid.
- Waste events
Out of hours use on any pulse meter is raised against its expected pattern.
Pulse devices and what they report
| Device | Reading | Connection |
|---|---|---|
| Pulse counter | A pulse count, converted in the cloud with the meter's pulse constant into kWh, gallons or cubic feet, plus demand or flow. | LoRaWAN. |
| Pulse splitter | No reading of its own. It passes one pulse output to two systems with no added load. | Wired, passive. |

Common questions
The quantity one pulse represents, such as 1 kWh or 10 gallons. It is printed on the meter or its datasheet and set once in Aqueduct, which then converts each count into consumption. See water meters.
No. The splitter is passive, so the BMS or EMS keeps receiving the same pulses while Aqueduct counts them too. Both systems then see identical consumption. See keeping your BMS.
Most installed utility meters. If the register has a pulse output, whether it counts volume or kWh, a counter can be wired to it, and the datasheet confirms the output type and constant. Meters without one can use a camera reader instead. See cameras.
Interval data. A meter read monthly by hand starts reporting every few minutes, which supports weather-normalized baselines, bill checks and out-of-hours waste alerts in Aqueduct without replacing the meter. See utility bill validation.
See Aqueduct on your own facility.
