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.

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.

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.

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.
