Very easy to retrofit on new and older tanks. No drilling or disassembly of the tank is required. Measures from the outside, never risk of leakage.

Equaly simple and ingenious as Gobius 4 for waste tanks. But here it glows red when the tank is becoming empty, and it is time to refill it. Shows 4 levels, empty, 1/3-, 2/3- and full. 3 sensors mounted (glued) with a 3M adhesive tape on the outside of your tank.

All included: 1 LED panel (display), 1 control unit, 3 sensors (1 m cable), 1 DC cable (1,8 m), 1 panel cable (1,5 m), 1 3M Surface cleaner, 1 extra sensor 3M VHB tape, 1 Velcro band (Control unit) and instructions in English. Version 5.0.
