AutoAqua RO/DI Flood Guardian

<h1>RO/DI Flood Guardian</h1> <p><strong>Automatic shut-off protection system for safe and reliable RO/DI water reservoir filling.</strong></p> <h2>Overview</h2> <ul> <li>Automatically shuts off RO/DI systems when the target water level is reached.</li> <li>Prevents accidental overflows and water damage.</li> <li>Simple one-button filling operation.</li> <li>Ideal for saltwater mixing stations, ATO reservoirs, water jugs, and storage containers.</li> <li>No timers, adjustments, or monitoring required.</li> </ul> <h2>Model Information</h2> <ul> <li>Model: ASOV-202V</li> </ul> <h2>Key Features</h2> <h3>One-Press Filling with Automatic Stop</h3> <ul> <li>Start filling with a single button press.</li> <li>Automatically shuts off when water reaches the sensor level.</li> <li>No timer setup or manual supervision required.</li> <li>Electronic shut-off valve responds instantly.</li> </ul> <h3>Dual Optical Water-Level Sensors</h3> <ul> <li>Uses dual optical sensors instead of mechanical float valves.</li> <li>Primary sensor detects water level with precision.</li> <li>Secondary sensor provides built-in overflow protection.</li> <li>Reliable electronic detection with no moving parts.</li> </ul> <h3>Magnetic Sensor Mounting</h3> <ul> <li>Sensor mounts securely using magnets.</li> <li>No drilling or permanent installation required.</li> <li>Easily repositioned between reservoirs.</li> <li>Compatible with most common reservoir walls.</li> </ul> <h3>Plug-and-Play Installation</h3> <ul> <li>Everything required for installation is included.</li> <li>No plumbing modifications or programming necessary.</li> <li>Quick installation in just minutes.</li> <li>Simple tubing and power connections.</li> </ul> <h3>Clear Status Indication</h3> <ul> <li>LED indicators provide quick status confirmation.</li> <li>Audible notification alerts when filling is complete.</li> <li>Easy-to-read operating status at a glance.</li> </ul> <h2>Benefits</h2> <ul> <li>Eliminates the need to monitor filling containers.</li> <li>Prevents floods caused by forgotten RO/DI systems.</li> <li>Safer and more reliable than traditional float valves.</li> <li>Easy to transfer between different containers.</li> <li>Normally-closed solenoid valve design helps prevent flooding in the event of failure.</li> </ul> <h2>Technical Background</h2> <p> Unlike traditional mechanical float valves that can clog, leak, or stick over time, the RO/DI Flood Guardian uses dual optical sensors and an electronically controlled solenoid valve for precise water-level management. The normally-closed valve design adds an additional layer of safety by defaulting to the closed position during power loss or abnormal operation. </p> <h2>What's Included</h2> <ul> <li>RO/DI Flood Guardian Controller</li> <li>Universal Power Adapter</li> <li>DC Solenoid Valve</li> <li>RO Tubing Holder</li> </ul> <h2>Specifications</h2> <table border="1" cellpadding="8" cellspacing="0"> <thead> <tr> <th>Specification</th> <th>Details</th> </tr> </thead> <tbody> <tr> <td>Model</td> <td>ASOV-202V</td> </tr> <tr> <td>Power Input</td> <td>100–240 VAC 50–60 Hz</td> </tr> <tr> <td>Power Output</td> <td>12 VDC / 1A</td> </tr> <tr> <td>Power Cord Length</td> <td>6 feet (180 cm)</td> </tr> <tr> <td>Solenoid Valve Power</td> <td>6W @ 12 VDC</td> </tr> <tr> <td>Solenoid Valve Pressure</td> <td>0.02–0.7 MPA</td> </tr> <tr> <td>RO Tubing Port</td> <td>1/4-inch RO Tubing Connection</td> </tr> <tr> <td>Solenoid Valve Cord Length</td> <td>4 feet (120 cm)</td> </tr> <tr> <td>Maximum Sensor Mount Thickness</td> <td>1/2 inch (12.7 mm)</td> </tr> <tr> <td>Tube Holder Mount Thickness</td> <td>1.2 inches (30.5 mm)</td> </tr> <tr> <td>Sensor Cable Length</td> <td>10 feet (300 cm)</td> </tr> </tbody> </table> <h2>Installation Notes</h2> <ul> <li>Mount the solenoid valve securely in the upright position.</li> <li>Keep the valve away from moisture and water splashes.</li> <li>Follow the directional water flow arrow on the solenoid valve during installation.</li> <li>Designed for easy setup without permanent modifications.</li> </ul> <h2>Additional Information</h2> <p> The RO/DI Flood Guardian allows aquarium hobbyists to safely prepare RO/DI water while performing other maintenance tasks. Simply start filling and let the system automatically stop at the correct water level. </p>
