The Gobius C (NMEA 2000) Tank Monitor is a revolutionary, non-invasive liquid level sensor designed to integrate seamlessly into your vessel's onboard network.Unlike traditional in-tank sensors that are prone to fouling, clogging, and corrosion, the Gobius C mounts securely to the outside top of your tank using pre-applied 3M adhesive tape—completely eliminating the need to drill holes or risk leaks.Utilizing advanced micro-radar technology, it silently and continuously measures fluid levels with extreme 2–3 mm accuracy, working perfectly through polyethylene, fiberglass, and glass tanks up to 2 meters deep.Equipped with plug-and-play NMEA 2000 connectivity, it feeds real-time volume and level data directly to your multifunction chartplotter, while built-in Bluetooth 5.0 and the Gobius C mobile app make calibration, tank geometry calculations, and remote phone monitoring incredibly simple.Highly versatile, it is compatible with all fluid types—including water, fuel, grey water, and black water—offering an effortless, maintenance-free upgrade for modern boaters.
