At a time when fuel prices fluctuates and actual consumption becomes a critical indicator, it is essential for professionals to check the fuel level in each tank. Whether it’s a vehiclea storage tankor an isolated site, an incorrect gauge reading or a lack ofreliable information can lead to breakdownsfailures delaysor even hidden costs costs.

Thanks to connected monitoring systemsit is now possible to take an accurate precise fuel level measurementautomate monitoring and detect any anomaly: leakage, theftor sensor failure. The aim of this article is to introduce you to the most frequent problemsproblems existing solutionsand concrete benefits of a remote monitoring product for fuel.

For a company managing a fleet of vehicles, fuel represents a significant proportion of the logistics budget. In some sectors, such as road haulage or agriculture, this item can climb even higher, having a direct impact on the profitability of operations.

Fuel losses come from several sources:

• Leaks due to wear and tear or tank failure
• Manual siphoning or automated theft during parking
• Over-consumption due to poor engine maintenance or inefficient driving
• Human errors in reading or entering measured levels

The absence of a reliable level monitoring system makes it difficult to detect these discrepancies. The result: expenses that go undetected, volumes consumed that are poorly accounted for, and inadequate control of fuel costs.

The fuel theft is a well-known phenomenon in industrial, agricultural and construction environments. Methods range from the simple hose siphoning to direct handling of the level sensor. Most often, this happens on building sites, in isolated areas or in unguarded parking lots.

Conventional solutions, such as lockable plugs or manual inspections, are no longer sufficient. They are time-consuming, unreliable and, above all, reactive rather than preventive.

Conversely, a solution with an on-board sensor enables :

• A follow-up regularly of the level of each reservoir or tank
• From automatic alerts in the event of an abnormal drop or manipulation
• Data logging (historical readings) for proof or post-incident analysis
• Position tracking for equipment with GPS trackers

These measures help to protect resourcesbut also empower drivers and and operators in the field.

In addition to the economic aspects, poor fuel management fuel poses a environmental problem. Undetected leaks, overconsumption due to engine faults or overfilling can lead to serious damage. unnecessary CO₂ emissions and risks of soil pollution (particularly in the event of tank overflow).

In addition, certain regulations encourage (or require) companies to measure and reduce their carbon footprint. This is particularly the case in industrial sectors subject to standards such as :

• ISO 14001 environmental management
• SEQE-EU (European system of carbon quotas)
• Local tax incentives for energy monitoring technologies

By automating precise measurement of fuel volumecompanies can not only limit lossesbut also enhance their environmental commitment.

An efficient fuel fuel level monitoring system depends above all on the choice of sensor adapted. Each technology has its own advantages in terms of precisionand costand volume and installation conditionsinstallation.

Every level sensor is selected according to the type of reservoirthe type of fuel (diesel, gasoline, water) and use (mobile or stationary).

Once the data has been measured, it must be transmitted to the monitoring platform. This is done via low-speed IoT networksnetworks, chosen according to location, network network coverage and energy consumption consumption.

The choice of network has a impact on system reliabilityparticularly in isolated areas or dense industrial environments.

An up-to-date coverage map of IoT operators is recommended to validate the most suitable technology for your installation site.

✅ Good to know : Four Data provides a free tool to test network coverage (LoRa, Sigfox, LPWAN) directly on your operating site.

👉 Test your site’s network coverage

All the data transmitted is centralized in a software interface accessible remotely. This tool is the heart of the system management.

Key features include:

• Visualization of level of each tank or reservoir
• Measurement historytrend curves, multi-site comparison
• Automated alerts in the event of a rapid drop or critical threshold
• Download activity or or anomaly reports
• Links with other connected equipment or business software

Example: a logistics manager can receive an SMS alert when a tank falls below 15% volume, enabling an immediate immediate reaction.

Install a remote fuel level fuel level monitoring system enables immediate rationalization supplies. With reliable, real-time dataLogistics managers can avoid :

• Unnecessary deliveries (tanks still full)
• Supply disruptions
• More costly emergency interventions

Typical customer feedback shows savings of between 10% and 20%. on the fuel budget from the very first year. These gains can be explained by better filling planning and a reduce wasted volumes.

Thanks to the integration of an automated automated monitoring systemmany previously manual tasks are now handled by the solution:

• Automatic generation of consumption reports
• Detection and notification of critical levels
• Replenishment forecasts based on historical data
• Multi-site monitoring from a single point of entry

This frees up operator time and eliminates the human errors associated with manual readings. manual readings or approximate entries.

📈 Suggested simplified workflow :

1. Sensor detects low level
2. The alert is sent automatically
3. The software proposes an optimized filling date
4. The driver is informed via the mobile application

Have a clear dashboard has become essential for resource management. A good remote fuel monitoring tool offers views adapted to different profiles:

• Supervisors : overview of remaining volumes
• Finance : vision by site, with aggregation of volumes consumed by liquid type
• Technical : history of sensor failures and anomalies

Example of a dashboard :

• Current levels per tank
• Daily consumption history
• Alerts triggered during the month
• Performance comparison by vehicle or machine

In industrial environments, accurate fuel level management is crucial to ensure continuity of operations and avoid costly interruptions. Our monitoring solutions enable real-time measurement of the volume of fuel in tanks, facilitating supply planning and rapid detection of anomalies.

In oil depots, for example, the integration of connected level sensors has reduced losses due to leaks and overfilling, while optimizing refueling rounds.

In the agricultural sector, farms are often located in rural areas with limited connectivity. Our fuel level monitoring solutions are designed to operate autonomously, with low power consumption, ensuring reliability even in the most remote areas.

The right sensor is not the one that offers the highest absolute accuracy, but the one that is adapted to your environment and your constraints: type of tank, type of fluid (fuel, water), accessibility, available power supply.

The Four Data solution is designed to integrate easily into your existing business tools, thanks to :

• A API for data transmission (level, alert, volume consumed)
• Compatibility with ERP solutions ( iCopitole and PTV group ) info : Four Data general presentation .pdf
• Secure connection mode (HTTPS, authentication token)
