You always get the exact level in your tanks, no more guessing.
Gobius C was developed for those who want to know the exact tank level, eliminating guesswork and unpleasant surprises. You may have bitter experiences with sensors inside the tank, which you can never trust.
Precise and straightforward so that you can “C” the level in your tank exactly.
Click on Installation, and you will see how easy the installation process is.
The sensor is mounted with pre-installed 3M tape for plastic and fiberglass tanks.
A hole (min. 50 mm) is required if you have a metal tank. Our new Gobius C adapter fits perfectly for the standard hole (1 1/4″ or SAE 5) used by KUS, Wemas, and similar tank sensors.

Leif (Greve, DK) 1 January, 2026I needed a new tank sensor and decided I wanted something that would give me the status on SignalK. I bought the Gobius C Basic with a metal tank adaptor, and it was very easy to get working. But I will need some help configuring the tank.

A Combination of Gobius Technologies
We are proud of our new software, Wave-Damp. It is automatic correcting the measuring for waves in the ocean.
We have also developed a new tank level/volume calculation software, which takes into account the geometry of the tank to be able to specify the exact level in the tank (% and volume) both visually on your phone and also on external devices.
We also have a new damp feature, making the measurement even more realistic when the Gobius C is mounted in a boat out on the sea in big waves.
By combining these functions together with a micro radar sensor, we now offer an unbeatable product for smaller tanks (up to 2 m high), such as water, fuel, and waste tanks, at an unbeatably low price.
Gobius C vs. Other indicators
Gobius C
- Measures from the outside of the tank (metal and plastic tanks)
- Stepless measurement, 2-3 mm accuracy
- Instant showing the correct level and volume
- Reliable, never in contact with the fluid water
- Smart software to eliminate wave motions
- Built-in tank calculator to provide the exact fluid level
- Easy installation with your smartphone (Bluetooth) or PC
- Easy to integrate with control systems and external devices
- Integrated instant support functions
Other indicators
- Measure inside the tank
- No exact stepless measurement
- Never correct measurement
- No tank shape correction
- No wave correction
- Unreliable, always in contact with aggressive fluids
- Indicate full even if the tank is empty
- Drilling holes are needed
- Always a leakage risk
Micro radar vs. Ultrasonic
Micro radar measurement (Gobius C)
- Measure through plastic, glass, and fiberglass
- Does not measure through metal
- Not affected by temperature
- Not affected by foam, vapors, pressure, and dust
- Measure very fast, more than 1 time/sec.
Ultrasonic measurement
- Measure inside the tank, never from the outside
- No exact steps measurement
- Does not read through plastic and fiberglass
- Does not read through metal
- Affected by temperature
- Affected by foam, vapors, pressure, and dust
- Measure slow, 4-5 seconds each time
- Drilling holes are needed
- Always a leakage risk
- Complicated installation
