External Fluid Level Sensor Masters Varied Tank Shapes

Gobius C from Albin Group Marine

Feb 7, 2023

From cone to cube, the Gobius C from Albin Group Marine precisely measures the exact volume and fluid level in tanks of virtually any shape, no matter the number of sides or angles, or composition. Taking only 15 minutes to install and configure, the maintenance-free device mounts externally.


What separates the Gobius C from traditional internal mechanical sensors is the ability to provide stepless 1-100% measurements without the annoying needle jumping that boat owners are so used to. It’s also more precise, providing readings within 3mm.
This is accomplished by an innovative micro radar built into each device. The sensor transmits electromagnetic waves through the metal, plastic or fiberglass tank wall, measures the reflected vibrations, then delivers a signal to the integrated processor that in turn sends to the display device.

Because the Gobius C is external, it’s unaffected by the solids and slurries common in black water tanks that impede internal mechanical sensors. Nor do excessive temperatures, pressure and foam interfere with readings, all of which play havoc with an ultrasonic sensor. Plus, as contents move due to vessel motion, the processor automatically eliminates variances and displays an even reading.

The Gobius C measures 2.16″ H x 3.74″ dia. and requires no drilling, so it’s simple to mount onto a preinstalled tank with the included 3M tape. It works on containers that are greater than 7.8″ H, but less than 78″ H. Consuming only 10mA, the device runs on 9–28V DC and has digital IP44 female 8-pin output connectors and an integrated 3.3′ cable. A built-in LED glows to indicate it’s running.

Once the Gobius C is installed, it’s simple to monitor readings using the companion Android or iOS app or PC interface. The Globius C is available across Canada at US$390.

While Canadians may have been slower to warm to pontoon boats than our southern neighbours, that’s definitely changed as we see more of them gracing our waters every year. The latest data shows pontoon boats now represent around 30% of all new boats sold in Canada and it’s easy to understand why – with their interior space and tremendous versatility, pontoons are near-perfect family runabouts.

Cruising Georgian Bay’s 30,000 Islands: Canada’s Freshwater Paradise for Boaters

The Plan

It’s a beautiful morning as we perform our pre-departure checklist, fire up the engines and prepare to release our lines. And if the long-range forecast of very low winds coupled with plenty of sunshine holds, that’s exactly what we need for the areas we plan to explore on this trip! 

We are departing Midland for a week of visiting some of the islands and anchorages within Georgian Bay’s “30,000 Islands” – specifically those along the western edge. These are the less protected islands which face toward wide-open Georgian Bay, where boaters often have to depart the small craft route and work a little harder at setting the hook but are then rewarded with magnificent western views, stunning sunsets, and so much to explore!
