The FullUP oil gauge with input from Sirris

Smart oil tanks: Sirris is involved in designing the ultrasound measurement sensor for the new FullUP gauges.

The new smart gauge developed by Namur-based start-up FullUP makes it possible to track your oil consumption on your smartphone and receive an alert before the oil runs out. With the application you can order your oil with a single click and enjoy a bundled purchase price. At the heart of the system is a high-performance measuring gauge developed in collaboration with Sirris.

 

  • The FullUP concept involves a smart gauge measuring your oil level and sending the information to your smartphone.
  • The main challenge is to increase the reliability of the ultrasound measurement system chosen by FullUP.
  • In this light, Sirris developed a customized sensor whose parabolic transmission cone focuses the ultrasound on the surface of the oil, improving the reliability of the measurements.

FullUP offers individuals, institutions and businesses alike a smart solution to measure the level of their oil tank and communicate the relevant information via smartphone. Active since mid 2016, this Namur-based start-up has already fitted out a hundred tanks in Belgium and is rolling out in few European countries.

"Ultrasound naturally scatters in all directions. By focusing it on the oil surface, we get more reliable measurements.

Room for improvement

The smart-sensor concept developed by FullUP is a straightforward one: the sensor is fitted to the oil tank like a plug. Its sensor detects the oil level using ultrasound, and a transmitter connected to the Wi-Fi network sends  the information and any alerts to your smartphone. However, the measurements carried out by the standard sensor that was originally used when developing the product were unreliable. Also, it was not unheard of for the housing to crack when the device was fitted. In this light, there was a need to develop a more robust and efficient sensor.

Customized sensor

FullUP gave Sirris the task of developing its own sensor. The Sirris team has developed a robust housing, building in for example a parabolic ultrasound transmission cone. Specially designed to focus the transmission of ultrasound to the surface of the oil, it enables more accurate and reliable measurements. Building in a temperature sensor also makes it possible to make measurement corrections depending on fluctuations in the climate. 

Commercial production

For the manufacturing of the sensor, Sirris chose materials meeting the tightness specifications and ATEX standards. It also ensured their moldability and ease of assembly, with a view to minimizing manufacturing costs. A prototype using additive manufacturing was produced in spring 2016. The precision and resistance tests were resounding success, and so commercial production started in the months after that.
