QatrahMade in Amman
Every drop counted.
Eight parts. One small sensor that sits on your rooftop tank and tells your phone how much water is left.
Inside
Built for a hot roof.
A sealed enclosure, a waterproof ultrasonic transducer facing the water, and a long-range radio that reaches the gateway inside your home.
No Wi-Fi on the roof. The sensor talks LoRa; the gateway handles the internet.
Assembled
One sensor.
It never touches the water. It measures how far the surface is and works out the rest.
How it measures
Listen for the echo.
A pulse goes down, bounces off the water and comes back. That echo tells us exactly how much is left.
Day and night
Clear as water.
The sensor checks every few minutes, so nobody has to climb to the roof to look inside the tank again.
The app
Your tank, in your pocket.
Every tank in the house on one screen: how full it is, whether water is being used right now, and how long it will last.
Forecast
Days, not guesses.
Qatrah learns how your home uses water and turns the level into a forecast, so you know you have about 12 days before the next refill.
Alerts
Warned before it's empty.
When the tank drops below your threshold, your phone tells you. Leaks, overflows and a sensor that stops reporting raise an alert too.
Refills
Every refill, logged.
Mains, tanker or pump: Qatrah spots each refill on its own and records how much came in, so you can check what you paid for.
