Gear: Bluetooth Device Addresses Marine Tank Sensor Problems

Gobius Pro Tank Gauge

Nov 24, 2022

Internal mechanical marine tank sensors are plagued with problems that cause inaccurate readings. Jostling fluid will move the float—even in containers with baffles—and over time, arms and pivot points tend to get sticky. Capacitive sensors can likewise fail once they accumulate calcium, magnesium, phosphorus alloys and other chemicals. The wireless Gobius Pro from Albin Group Marine overcomes these issues. Ideal for refit or OEM use, the innovative device is completely external; it measures from the outside of metal, plastic or fiberglass tanks.

The patented Gobius Pro emits vibrations into the tank that its integrated accelerometer reads, then transmits this data via Bluetooth to the companion mobile app. Featuring dual digital outputs with on/off signals, it also integrates into NMEA 2000 (See last issue’s Ask Andrew column) BUS and other relay systems. It automatically calibrates for the tank material and contents, and works with all marine fluids such as fuel, oil, and fresh, grey and black water. The app will pair with up to nine devices installed throughout the vessel. A video is at www.bit.ly/GobiusPro.

Unlike other sensors that require removing, drilling or cutting the tank, installing the Gobius Pro is a simple 15-minute task. Extremely compact at only 2-3/4″ dia. x 1″ H, it’s easily mounted on a fitted tank with the supplied 3M tape. Because holes aren’t needed, there’s no risk of fluid or vapour leakage. The device supports 12-24V and draws a mere 10mA when idle and 100mA while measuring.

From complex to simple, Albin Group Marine offers other Gobius models for a range of applications. For stepless 0–100% measuring to within 3mm, the Gobius C is ideal, especially for unusually shaped fuel, oil, water or holding tanks. It requires only a single sensor, mounted externally on top, and transmits data via Bluetooth or BUS network.
Alternately, the base level Gobius 1 is a 3/4 level alarm for waste holding tanks. It consists of an external sensor, panel and control unit. It can be wired up to 164′ away with a standard PC network Cat 5 cable.

Available widely across Canada, the Gobius Pro tank sensor retails for US$199. The Gobius C is US$390 and the Gobius 1 costs US$199.

Nimbus 365 Coupe – A real long-stay cruising boat for exploring

By Andy Adams

There is no shortage of fun and exciting new boat designs hitting the market, but for the last few years these have been mainly outboard-powered day boats. Some are day cruisers; some are centre console fishing boats or designed for tow sports. A new live-aboard cabin boat has become a rare item these days.

So when I heard that Pride Marine in Orillia, Ontario, had a Nimbus 365 Coupe in the water, I jumped at the chance to get out on it.

Tahiti—Updates from Paradise

By Zuzana Prochaska

I’ve been to Tahiti seven times—six on charter and once as crew for a couple of yachties. Over the 25 years that I’ve been visiting, it’s changed dramatically. Yet, inexplicably, it has also stayed the same.

Lounging on the flybridge of our Sunsail 454, I had time to think about this dichotomy as I toasted the nighttime skies of Bora Bora and specifically the Southern Cross, a constellation that never fails to hypnotize. As the Crosby, Stills & Nash (1982) tune reminds us:

…you understand now why you came this way.
