Hydraulic Automatic Flood Barrier
How It Works
- Automatic Mode (Primary Operation)
- Barrier activates automatically via water level sensor when floodwater reaches preset height
- Built-in buzzer sounds 8-second warning before deployment
- No human intervention required—ideal for rapid-onset flooding
- Semi-Automatic Mode
- Manual trigger via control panel “Up”/“Down” buttons
- 8-second audible warning before movement
- Used for scheduled testing or pre-flood deployment
- Remote Control Operation
- Wireless remote control for barrier raising/lowering
- Enables operation from a safe distance or control room
- Manual Override
- Fully mechanical operation via hand pump and manual rod
- Ensures functionality even during total power/system failure

Faq
How does automatic activation work?
A water level sensor triggers deployment when flooding reaches a preset height (typically 5–15 cm). The system is fully autonomous.
What happens during a power cut?
The integrated battery backup supports at least 10 full raise/lower cycles, ensuring operation during extended outages.
Can the barrier be integrated with existing flood alarms?
Yes, the system can be wired into SCADA, BMS, or telemetry systems for centralized monitoring and control.
Is it suitable for saltwater environments?
Yes, with marine-grade stainless steel and sealed components, it is designed for coastal and tidal locations.
What maintenance is required?
Monthly visual checks and an annual professional service. Battery replacement every 3 years.
How long does installation take?
Typically 3–5 days for embedded systems, 1–2 days for surface mount, depending on site conditions.
Automatic When Needed. Manual When Required. Reliable Always.
