Core features
Accurate water & gas metering
Real consumption in real time with long-life internal sensors.
Integrated motorised valve
Open, close or partially close remotely — billing control, safety, emergencies.
Ultra-low power
No flow → deep sleep; wakes periodically to send data.
Long battery backup
A built-in battery keeps it alive even without flow.
Future-ready sensors
Room for water-quality sensors (pH, turbidity) in later versions.
How it works
-
STEP 01
Install
Fits on the pipe — water or gas.
-
STEP 02
Power
The built-in hydrogenerator runs on the flow itself.
-
STEP 03
Measure
Sensors record usage and operating data.
-
STEP 04Report
Data goes to the operator dashboard: Grafana or the Tech 404 server.
-
STEP 05Control
Open, close or set the flow remotely.
Use cases
- Municipal water utilities
- Gas distribution networks
- Residential & commercial buildings
- Industrial facilities
- Construction sites
- Remote or off-grid infrastructure
