10 Best auto top off Reviews of 2021
- Compact size - the entire optical sensor unit ONLY 0.8 inches diameter. The unit works on rimmed and rimless tanks, and as well as sump tanks. The dual precision optical sensors are 0.1 cm apart, which enables it to monitor the level fluctuation precisely (less than 0.6cm difference)
- New and Improved Features - Upgraded ETFT (Extra Time Filling Technology), AFT (Anti-fluctuation Technology), and QST 2.0 (Quick Security Technology). With all these new upgrades combined, our ATOs are far superior and safer. ETFT recognizes your tank size after it first initialized. Working alongside the ETFT, the AFT will be able to decide how long it takes to refill your tank without over-filling it when the QST alarm is triggered.
- QST 2.0 provides real-time protection against overfilling and pump dry run. The controller will give a visual alert and stop the pump immediately when it senses a refilling time more than 6 times longer than the time calculated by ETFT. QST can detect a malfunction of the sensor/controller or even an empty reservoir.In version 2.0 we incorporate ETFT feature and not relying on first filling time from version 1. Flooding barely happens when following the instructions carefully.
- Everything you need is included in the package. Powerful magnet supports 15mm thick glass wall. Check valve prevents water from back flowing from the tank. Hose holder allows you easily secure the tubing. Powerful 70gph water pump can lift water up to 2.5 m high.

- Compared to the old ATO, we have upgraded two parts of this ATO. 1. replaced the original submersible pump with a new anti-dry submersible pump. 2. replaced the new sensor, the new ATO uses a more accurate optical level sensor more responsive, which can effectively reduce the generation of faults.
- Please install the sensor correctly (there is a picture illustration in the main picture), ATO may malfunction will not work. The height difference between the refill bucket and the bottom/master cylinder should not exceed 1.5 meters, and the refill bucket level should not be higher than the bottom/master cylinder level as much as possible .
