Never Run Out of Water.
Smart water tank controllers that monitor level, auto‑fill, prevent dry run, and send alerts to your phone. Save water and electricity.
Smart Water Management Made Simple
Smartphone Monitoring
Check water level, pump status, and consumption history from anywhere using our mobile app. Real-time alerts included.
Automatic Fill Control
Pump turns on when water drops below a set level and stops at full – no more overflow or dry running.
Smart Sensor Technology
Ultrasonic or pressure‑based sensors provide accurate level readings without touching the water.
Dry Run Protection
The system automatically cuts off the pump if water source runs dry, preventing damage.
Leak & Overflow Alerts
Get instant push notifications if a leak is detected or if the tank overfills due to sensor failure.
Scheduled Pumping
Set timers to fill tanks during off‑peak electricity hours (e.g., 2 AM – 5 AM) to save costs.
Water Usage Analytics
Track daily/weekly consumption graphs. Identify unusual usage patterns and save water.
