RAS flood sensor

RAS flood sensor

Capacitive water level sensor for the RAS flood alarm system. Installed at the low point of an underpass or tunnel, it detects rising water and signals the RAV/RAS control unit, which then activates the connected warning devices: LED flashers, red traffic lights and the LED message panel showing FLOODED TUNNEL. Drivers are warned before they enter a flooded section. The system can be powered at 230 V or from a photovoltaic kit, and can be integrated with a 4G router to alert the responsible authority.
