Connected tank – Monitor your levels in real time
The connected tank transforms the way you manage your stocks of fuel, water or chemicals. Thanks to an intelligent gauge equipped with a high-precision sensor, you have real-time access to the exact level of your liquids. No more time-consuming manual checks: data is automatically transmitted via a secure IoT network (Sigfox, LoRa, NB-IoT, LTE-M). Alerts, customized thresholds and an intuitive interface guarantee optimized management, controlled consumption and scheduled deliveries at the right time.
What is a connected tank?
Definition and operating principle
A connected tank is a reservoir equipped with a smart gauge and a high-precision sensor (ultrasonic, pressure or radar) that continuously measures the liquid level (fuel, water, oil, chemicals). The data is automatically transmitted via a IoT network networks (Sigfox, LoRa, NB-IoT, LTE-M) to a software platform.
On this interface, the client can consult its information at any time: remaining volume, daily consumption, thresholds reached. In the event of an anomaly or specific requirement, a alert is triggered automatically (SMS, e-mail, notification).
The limits of traditional tanks
- Time-consuming, error-prone manual measurement.
- High risk of rupture or overstock due to lack of accurate tracking.
- No automatic alerts → need to physically check each tank.
- Dispersed management: no centralized data or multi-site vision.
Why adopt a connected tank?
Adopting a connected tank means transforming management into a reliable, automated and secure process:
👉 Time-saving No more manual readings – everything is just a few clicks away.
👉 Information reliability Data is continuously updated, with no risk of human error.
👉 Peace of mind thanks to automatic alerts and configurable thresholds, you can anticipate needs and plan your deliveries without stress.
How does a connected tank work?
Intelligent sensors (ultrasound, pressure, radar, etc.)
Each connected tank is equipped with a intelligent probe adapted to the type of liquid to be monitored:
Sensor type | Preferred use | Advantages | Limitations |
---|---|---|---|
Ultrasonic | Fuel, water, standard products | Non-contact measurement, reliable outdoors | Sensitive to foam or deposits |
Pressure | Oil, dense liquids | High precision, suitable for underground tanks | Requires periodic maintenance |
Radar | Chemicals, hydrocarbons | Very high accuracy, insensitive to temperature | higher cost |
👉 The choice of sensor depends on the customer requirements nature of the liquid, environment (outdoor/indoor) and accuracy required.


Data transmission via IoT (Sigfox, LoRa, NB-IoT, LTE-M)
Once the measurement has been taken, the sensor transmits the level data to the platform via a secure IoT network:
- Sigfox / LoRa ideal for rural areas and isolated sites, thanks to their low energy consumption.
- NB-IoT / LTE-M ideal for urban and industrial environments, with higher throughput and 4G/5G coverage.

This flexibility guarantees continuous operation even in white zones. Visit battery for many years of maintenance-free operation.
Visualization and alerts via mobile and web applications
The data is centralized in a management software software:
Clear dashboard with level inconsumption history by day and trends.
Configurable alerts by threshold (e.g. low fuel level) sent by SMS, e-mail or notification.
Multi-tank and multi-site monitoring from a single interface, accessible via mobile or PC.
👉 Inspired by the above example, theintuitive interface interface makes it easy to manage your supplies and orders, while providing a consolidated view of all your tanks.

The concrete benefits of a connected tank
Anticipating disruptions and securing supply
Thanks to real-time monitoring and configurable alerts, you are warned before the level reaches a critical threshold. This enables you to anticipate deliveries and avoid business interruptions.
📊 Up to 35% reduction in breakage observed among users equipped with smart probes.
Optimize inventory management and reduce costs
A connected tank helps you better plan your replenishment and delivery rounds:
Before :
- Scattered manual controls.
- More unnecessary journeys.
- Incorrectly sized stocks.
After :
- Tours optimized according to actual levels.
- Reduce unnecessary travel.
- Less fuel consumption and logistics costs.
👉 The result: direct savings and smoother day-to-day organization.

Improving safety and reliability
Precise level monitoring reduces the risk of overflow, leakage or mishandling. Centralized data guarantee better traceability, reassuring both your teams and your customers.
Connected tank applications
Sector | Liquids concerned | Key benefits |
---|---|---|
Agriculture | Fuel oil, water, liquid fertilizers | Avoid machine breakdowns, manage irrigation, optimize use of resources |
Industry | Oils, lubricants, solvents, chemicals | Strict traceability, safety compliance, incident reduction |
Transport & logistics | Fuels, depots, stations, fleets | Delivery planning, multi-site monitoring, business continuity |
Residential | Oil, water, domestic heating | Assured comfort, low threshold alerts, everyday peace of mind |
