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 the 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, measuring the vibrations caused by the force and transmitting the signal to the sensor processor. The processor’s algorithm calculates a vibration value each time the sensor measures.
The Gobius Pro sensor is mounted outside metal or plastic fluid tanks—no more mounting on the inside of the tank, no more drilling of holes. The sensor can work alone or with several Gobius Pro sensors on a tank. 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 wastewater.
Gobius Pro vs. Old 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 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

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

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

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

“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.

New add-on products
We have expanded our product family with several products.
With these you can easily connect our tank sensors with analog instruments and NMEA2000 systems.
The app
The Gobius app is used to program the initial settings of the sensor, display measurements, as well as function as a platform for remote support. You can customize the setup for your application, as well as name and group sensors.
Software updates, instructions and support are done via your phone. The languages are English, French, German, Italian, Norwegian and Swedish.
Gobius Pro sensor technology
System integration
The sensor allows integration to operating systems in different ways. 2 digital outputs with on/off signal are included for connecting to external system. A signal can be received at various liquid levels for control of e.g. pumps. The system also supplies relays (12/110/230 Volts) and GSM units for surveillance and reporting of tank level information.
Strenghts:
– Quick and easy installation
– Bluetooth communication
– 2 Digital outputs, on/off signals
– Mounted on the outside of the tank, nothing on the inside
– No drilling of holes
– Easy to retrofit on an already installed tank
– Never in contact with the contents of the tank
– Handles tanks with aggressive and sterile liquids
– No maintenance
– No risk for leakage or odour
– Cost-effective
For all these tank materials, max:
– Stainless steel, 3 mm
– Steel, 3 mm
– Polyethene, 12 mm
– Fibre Glass, 8 mm
