Understanding the connected oil tank gauge
What is a connected gauge and how does it work?
A fuel gauge is an smart sensor that provides know in real time the oil level in your tank. It works on a simple principle: the sensor measures the height of the liquid inside the tank converts this information into volume then transmits it via an IoT network network to a mobile interface or a web platform.
Thanks to this technology data accessible at any time: you can track your consumption anticipate your needs, and avoid breakdowns. In Belgium, this type of connected solution is perfectly suited to both domestic and professional installations.
💡 Myth vs. reality
A connected gauge doesn’t just display the level: it analyzes the data to anticipate needs.
Technologies used: ultrasonic, pressure, IoT and ATEX sensors
Our connected gauges adapt to every type of oil tank or vat with a wide choice of measurement technologies and IoT networks.
They are suitable for individuals and professionalsand can be fitted to tanks for fuel oil, GNR, water, gas or biofuels including in ATEX (environments.)

Choosing the right connected gauge for your needs
Essential criteria: tank type, connectivity, autonomy, precision
Before investing in a fuel gaugeit is essential to assess the compatibility of your installation. Visit tank type (underground, overhead, steel or plastic), the available IoT network network (Sigfox, LoRa, NB-IoT), and theautonomy of fuel sensor directly influence the quality of data received.
On average, a Four Data gauge offers a service life years, without complex maintenance.
| Criteria | Detail | Importance |
|---|---|---|
| Tank type | Overhead, underground, plastic, steel | Compatibility to be checked |
| IoT network | Sigfox, LoRa, NB-IoT, LTE-M | Stable connection essential |
| Operating life | 3 to 5 years depending on battery and use | Durability and reliability |
| Accuracy | ±1% depending on sensor | Reliable data for monitoring |
How do you select the solution best suited to your needs (private or professional)?
The right choice depends on user profile and the actual need :
- Individual Prioritize ease of installation, l’mobile application and automatic alerts.
- Professional / operator give priority to multi-tank management management data centralization and long-range long-range connectivity.
- Distributor or supplier: choose a solution compatible with your supervision systems and logistics tracking tools.
