Say goodbye to unreliable tank gauges and messy internal senders with the Gobius C Wireless Micro Radar Tank Level Sensor (GST-970530). Using cutting-edge micro-radar technology, this innovative sensor measures fluid levels from the outside of your tank, completely eliminating the need for internal probes, drilling into plastic tanks, or risking leaks. Featuring stepless 2 mm measurement resolution, intelligent wave-dampening software, and seamless Bluetooth connectivity to smartphones and Victron GX devices, the Gobius C delivers exact real-time tank volumes in percentages, litres, or gallons.

External Non-Contact Mounting: Attaches to the outside of plastic and fiberglass tanks without drilling holes or contacting fluid, eliminating leak risks and sensor fouling. Stepless Micro-Radar Accuracy: Provides continuous, high-precision level tracking down to 2 mm resolution across tank depths ranging from 200 mm to 4500 mm. Intelligent Wave-Dampening: Features proprietary software that stabilizes readings against wave sloshing and road vibrations for steady, reliable data while underway. Universal Fluid Compatibility: Accurately measures all liquids—including fresh water, grey water, black water, diesel, gasoline, and oil—without sensor degradation. Seamless Bluetooth & System Integration: Wirelessly streams real-time tank data to the Gobius smartphone app, Victron Cerbo GX / Ekrano GX displays, and NMEA 2000 networks.

Product Details
Take the guesswork out of your onboard fluid management with the Gobius C Micro Radar Tank Level Sensor. Whether you are monitoring fresh water, grey water, black water, diesel, or gasoline on a boat, RV, or off-grid cabin, traditional internal senders often foul, corrode, or give false readings. The Gobius C solves this by measuring fluid levels directly through the tank wall from the outside.
Non-Contact Micro-Radar Precision
Unlike ultrasonic sensors that require internal access or mechanical floats that clog over time, the Gobius C mounts externally to polyethylene, fiberglass, or glass tanks using heavy-duty pre-installed adhesive tape. Its advanced micro-radar pulse penetrates the tank wall to deliver stepless, continuous fluid level readings with 2 mm accuracy. Because it never contacts the liquid, it is completely immune to foam, vapor, pressure, temperature shifts, and corrosive waste fluids.
Smart Wave-Dampening & True Geometry Volume
Fluid sloshing inside a moving vessel or vehicle can cause conventional gauges to jump wildly. Gobius C features proprietary Wave-Damp software that automatically filters out wave motion at sea or road vibration on bumpy routes to present a smooth, accurate reading. Paired with the free Gobius View app, the system calculates true volume based on your tank's exact shape - whether rectangular, tapered, or irregular - so you see exact volume in liters or gallons rather than misleading height percentages.
Bluetooth & System Integration
Integration into your vehicle or marine electrical system is clean and wireless. Built-in Bluetooth Smart connects directly to your smartphone for instant viewing, setup, and custom high/low level alarms. For integrated displays, the Gobius C communicates natively via Bluetooth with Victron Cerbo GX and Ekrano GX systems, as well as supporting NMEA 2000 and standard analog output protocols for full dashboard integration.
