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 leveland 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 andand avoid disruptions.
Our solution offers automated managementmanagement personalized alerts and a real-time visibility for smoother, greener and more profitable logistics.
Why adopt a connected gauge for your biofuel tanks?
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:
- Continuous fuel level monitoring in each tank, without physical displacement or approximation.
- Customizable automatic alerts according to defined critical thresholds (e.g. < 30% of volume), allowing you to anticipate replenishment before stock-outs occur.
- Reduced risk of running out of fuelwhich can lead to loss of business or immobilize a fleet.
- Remote visibility for professionals managing several geographically dispersed tanks.
- Case 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.


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.
- Fewer unnecessary journeysless fuel, less wear and tear on vehicles and less time spent on the road.
- Intelligent grouping of deliveries based on actual stock levels, not estimates.
- Direct 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.
Remote monitoring
Thanks to integrated connectivity (NB-IoT, LTE-M), each sensor installed on a tank automatically sends its data to a secure web interfaceaccessible from a computer or smartphone.
- Real-time visualization of the level of each tank, regardless of its location.
- Intuitive dashboardsCustomizable filters (by site, by fuel type, by threshold).
- Multi-user accessibility for logistics, purchasing or maintenance teams.
- Secure data hosting, with traceability of consumption.

Customer feedback
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,
- Precise monitoring of each tank’s level, accessible 24 hours a day,
- Save operational time and reduce unplanned interventions.
