Wireless Tank Monitoring

Installation

Sensor Technology with Bluetooth

You could say “Knock and listen” but it’s more sophisticated than that. The sensor technology is built on a method of monitoring local, mechanical properties of a fluid tank. A Gobius sensor exerts force onto a tank wall and causes it to vibrate. An accelerometer is part of the sensor and it measures the vibrations caused by the force and transmits the signal to the sensor processor. The processor’s algorithm calculates a vibration value each time the sensor performs a measurement.

The Gobius Pro sensor is mounted on the outside of metal or plastic fluid tanks. No more mounting on the inside of the tank, no more drilling of holes. The sensor can work alone on a tank but also together with several Gobius Pro sensors. The sensor has built-in (BLE) Bluetooth communication for Android and iOS phones. In addition, the sensor has two outputs for integration, for example, in Bus-systems, control relays, lights or buzzers. Useful for all kinds of fluids, like fresh water, fuel, oil, grey/black water and waste water.

Gobius Pro vs. Old Fashioned indicators

Gobius Pro

  • Measures from the outside of the tank (metal and plastic tanks)
  • Reliable, never in contact with the waste water
  • Easy installation with your smart phone (Bluetooth)
  • Easy to integrate with control systems
  • Integrated instant support functions

Old fashioned indicators

  • Measure inside the tank
  • Unreliable, always in contact with the waste water
  • Indicate full even if the tank is empty
  • Drilling holes are needed
  • Always a leakage risk

  • Like the inovative technique and I have 4 ea Gobius Control Boxes and now I have purchased a NMEA2000 Converter to see how I can benefit this system from within my 4 ea MFD Raymarine Axiom System
    all for an upcoming 4-5 year live aboard long sailing.

  • Hello,
    I am happy to report a successful installation of the three sensors!  The acetone wipe seems to have “done the trick”.  I also used some 50-grit sandpaper to create a rough surface. I have now wired up all three sensors and activated them with the app.  Everything is working well.

    Thank you for your excellent customer service after the sale.  I will be posting some pictures and a description of the Gobius Pro product to our user group – American Tug Owners Association.  Who knows, you may receive orders from some of them!

    Happy New Year!  I hope 2021 brings health and happiness to all of us.

    Sincerely, Tom Law

  • “I can tell you that we had chosen it because your product simply suits us very well. Your on ultrasound based measurement system can be easily installed for us. In Addition, it is very reliable and does not tend to fail – which is important for us and our customers. That’s why we chose your product back then and are still very satisfied with it”.

    Best regards,

  • Good day and regards from Croatia,
    “I installed 3 sensors in my sailing boat. 2 of them on a fresh water tank and one on the gray water tank. They should inform me on minimum and maximum levels, reminding me that I need to react. Application is very “user friendly”, both sensors and application are easy to install and easy to follow. Gobius “fishes” are also very practical and easy to spot !
    All together, You have a satisfied customer in Croatia, I am happy with my purchase !”

    Kind regards ! Danko Crncevic

  • ”Köpte denna då givaren i färskvatten gått i sönder. Har tidigare köpt en Gobius 4 för septitanken och blev väldigt nöjd med den så det självklara valet var givetvis ännu en Gobius 4 när givaren till färskvattentanken gick i sönder.”

    Hälsningar, Håkan Andersson.

  • “I Installed two of your sensors on my boat’s stainless steel black waste tank. Works really well; shared details at http://web.millican.info/Home/gobius-pro-tank-sensor and also on the Sealine forum. One suggested improvement for the software: it would be great if we could reorder the sensors on a tank and set their respective levels.
    Thanks for a great product.”

  • Hi Gobius Pro team.
    “Everything’s configured good now. The fish is on the second sensor (top) and the light switches properly. Thanks for help and patience. I want to congratulate you about the genius idea of creating this system.
    It’s really smart and useful.”

    Best regards, Ivo Stornaiuolo sailing in Norway

  • “I unlocked all the sensors and started  the installation from the beginning. Now everything is working fine and I also installed the Blackwatertank just with one sensor on the top. It‘s just great how it works. Thanks Gobius 👍I will positively recomend your product. Wish you all the Best and greatings from Chesapeake Bay.”

    Dominique Gueissaz at SV Prana Cat

  • “First, I’ll start out by saying that overall I am very pleased with the product. It was easy to install and calibrate. Also the support when I needed to order the longer wired sensors was great.
    You have a truly wonderful product.”

    Thank you, Paul Getman


  • “We purchased our Hanse 348 in the fall of 2019 and it came with a Gobius gauge for our black water tank. We are very happy with it and wish that they installed one on for our water tank as well. We have had to replace our water tank gauge already. You have a very good product and I would recommend it highly.”

    Tom Dwyer

  • I have now been able to get to my boat in Croatia and test the unit. And it worked straight away – perfect! Thanks so much for your support. I’ll certainly recommend you to all my boating friends.
