Gobius level indicator for water, oil, diesel, gasoline and waste

Gobius is the first and only level indicator in the world that can measure the contents in tanks made of any material, such as plastic, stainless steel, steel, aluminum and fibre glass, from the outside. Since it measures from the outside cleaning the tank or drilling holes is unnecessary.

Smart Patented Technology

Each sensor that is placed onto the tank wall consists of a shaker and an accelerator. When the shaker creates a vibration in the tank wall, the accelerator measures the size of the vibration and passes the data on to the control unit. The control unit then starts to calculate in order to give an exact estimate of whether the fluid level has passed the sensor or not.

Easy to calibrate

No tanks look the same. There are always differences in e.g. size, construction, thickness and age. In order to compensate for these differences you have to calibrate the tank before you start to use your Gobius. However, the calibration only takes a few seconds; all you need to do is to press a button.

Extremely low electricity consumption, less than 40 mA

Gobius is constructed to minimise electricity consumption and is extremely efficient. Gobius sends power to its sensors in impulses instead of a continuous supply, thus saving your craft’s 12-24 Volts battery.
