Oil Gaz · Connected gauge for biofuels
Connected gauge for biofuels monitor your levels remotely, avoid breakdowns
A connected gauge is an intelligent sensor installed on a tank or reservoir, enabling remote measurement of the fuel level and optimize fuel storage storage and refueling operations.
In a context of energy transition, biofuels biofuels such as HVO100 or B100 play a key role. To maximize their environmental impact, it is essential to secure their availability and and avoid disruptions.
Our solution offers automated management management personalized alerts and a real-time visibility for smoother, greener and more profitable logistics.

Improve supply reliability and efficiency
Why adopt a connected gauge for your biofuel tanks?

Stay ahead of replenishment needs
Optimize inventory management and avoid stock-outs
The use of a connected gauge on a biofuel tank enables eVMI (Electronic Vendor Managed Inventory) management, transforming a simple tank into an intelligent intelligent monitoring system. The benefits are immediate:
- 1Continuous fuel level monitoring in each tank, without physical displacement or approximation.
- 2Customizable automatic alerts according to defined critical thresholds (e.g. < 30% of volume), allowing you to anticipate replenishment before stock-outs occur.
- 3Reduced risk of running out of fuel which can lead to loss of business or immobilize a fleet.
- 4Remote visibility for professionals managing several geographically dispersed tanks.
- 5Case in point: a service station dispensing HVO100 can avoid unscheduled shutdowns thanks to accurate and frequent data feedback.
This connected approach is part of a drive for reliability, automation and a reduction in emergency interventions, while ensuring business continuity.

Smarter deliveries, lower costs
Reduce logistics costs and improve planning
By connecting your tanks to a tracking platform, delivery planning becomes data-driven routes are optimized according to actual needs.
- 1Fewer unnecessary journeys less fuel, less wear and tear on vehicles and less time spent on the road.
- 2Intelligent grouping of deliveries based on actual stock levels, not estimates.
- 3Direct improvement in carbon footprint:
– Up to -18% reduction in kilometers traveled
– That’s -12% CO₂ per ton delivered
– With an ROI < 9 months on equipment and installation.
These figures show that the connected gauge is not just a tracking tool, but a logistics logistics performance solution solution for companies.

Customer feedback

A successful deployment example
Case study : Oleo100, 100% French rapeseed biofuel
Background
The Group Avril wanted to increase the reliability of its supply of Oleo100, a biofuel produced from French rapeseed, while simplifying the management of tanks spread over different customer sites.
The issue
With growing demand for this alternative fuel, delivery coordination was becoming critical. Teams were faced with a lack of visibility on stock levels, leading to early replenishments, or conversely, risks of stock-outs.
Our solution
Four Data has deployed a set of ultrasonic sensors connected to customer tanks. All consumption data is uploaded in real time to our IoT platform. Thanks to an intelligent alert system, logistics teams are automatically informed of filling requirements.
The results
- Automated control via the eVMI interface,
