Remote Fuel Tank monitoring
NivelWatcher monitors the fuel oil level in your customers' tanks in real time, from a single dashboard. You know when they will need a refill before they call you. No urgent call-outs. No improvised routes. Real data from minute one.
Stay ahead of demand and build customer loyalty like never before
The biggest problem for fuel oil distributors is not the price. It is managing without visibility.
They don't know what is left in their clients' tanks until they ring with an empty one. By then, it is too late.
Every emergency delivery destroys the margin. Every improvised route drives up costs.
And it's a problem with a solution: a level sensor connected to our platform or yours, telling you exactly what's in each tank, at all times.
That's exactly what changes with NivelWatcher.

Main questions about NivelWatcher
The sensor continuously measures the level of the tank (using ultrasound or radar, depending on the installation) and sends the data to the platform via Sigfox, LoRa, or NB-IoT connectivity. The installation takes less than a minute and requires no construction: you place the sensor and start seeing the level of each tank from the very first moment. This way, you know what is left in each tank without relying on the customer to notify you.
Both measure the level without contact with the liquid. The ultrasonic works well in most diesel tanks and standard distribution. The radar offers greater accuracy in more demanding conditions (surfaces with foam, vapours, complex geometries, or industrial tanks). In a prior diagnosis, we define which one fits best with your tank fleet.
Yes. The platform analyses the actual consumption of each customer and predicts when they will need a refill, allowing for automatic order generation and prioritised route planning instead of reacting to calls for empty tanks. The result is fewer urgent deliveries, fuller routes, and lower cost per litre delivered.
You can work with our platform or integrate the sensor data into your own management software or ERP. The logic is to adapt the technology to your operations, not the other way around. It is common to start with a pilot on your own tanks and scale from there.
Do you want to stop reacting and start anticipating?
The first step is easy: a no-obligation diagnosis. From there, we set up a pilot on your own tanks.
