AutoAqua RO/DI Flood Guardian

One-Press Filling with Automatic Stop Start filling with a single button press, or by plugging in your Flood Guardian. When the water reaches the sensor, the electronic valve immediately shuts off the RO/DI water supply. There’s no timer to set and no adjustments required — simply begin filling and let the system handle the rest. Ideal for Saltwater Mixing Station, ATO Reservoirs, Water Jugs and More Perfect for saltwater mixing containers and RO/DI storage reservoirs. Water can be prepared while performing other tasks or tank maintenance, without monitoring the container. The system automatically stops when the water reaches the sensor level. Dual Optical Water-Level Sensors Dual optical sensors electronically detect water level instead of using traditional mechanical floats. The sensors directly detect the water level and control the electronic shut-off valve with precision. The secondary sensor provides a built-in safety backup to prevent overfilling. Reliable and Easy Upgrade over Float Valves Guided by dual optical sensors, the valve responds instantly and shuts off with precision — delivering consistent, dependable control every time you fill. Can be easily installed in a few minutes. No supervision required. Just automatic, accurate water management. Magnetic Sensor Mounting The sensor mounts securely using magnets. Positioning takes only seconds and works on most common reservoir walls. No drilling or permanent installation is required, and the sensor can easily be repositioned when needed. Plug-and-Play Installation Everything needed for installation is included. Simply mount the sensor, connect the RO tubing to the solenoid valve, and power on the controller. No plumbing modification, programming, or additional parts are required. Clear Status Indication The controller includes LED status indicators and an audible notification when filling is complete. You can quickly confirm the operating status at a glance, and the alert lets you know when the reservoir has finished filling.
