Gobius 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 digital 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 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

  • Internet.
    But there is someting wrong in the NMEA2000 protocol, the sensor is sending out.
    Instance number is not transmitted, but type number for liquid type is coming twice. Please see the standart for PGN127505.

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) 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
