Equaly simple and ingenious as Gobius 4 for waste tanks. But here it glows red when the fuel or water tank is becoming empty, and it is time to refill it. Measures from the outside. NOTHING ON THE INSIDE OF THE TANK. For tanks in metal as well in plastic.
The Gobius Measurement System is based on our patented technology that can best be described as "knocking and listening". The same version of our product works for tanks containing water, diesel, gasoline and other fluids.
