The system consists of a tank-mounted sensor and a digital management platform, designed for ease of use and broad compatibility. Installation takes less than a minute and the device is suitable for virtually any tank type. Once installed, NivelWatcher captures accurate tank level data and transmits it via Sigfox, LoRa, or Cellular NB-IoT networks to a centralised platform.
From there, distributors can monitor customer fuel levels, receive low-level alerts, and analyse usage patterns. The system enables proactive service, reducing unnecessary trips, minimising overstocking or empty runs, and improving route planning.
The management platform is accessible via mobile, tablet, or desktop and provides features such as demand forecasting, automated order generation, and historical usage analysis. This improves logistics efficiency and flexibility – adjusting deliveries in real time based on actual customer usage – especially important during volatile supply periods.
Celestia TST has a 15-year background in IoT development and digital transformation, and NivelWatcher reflects this with a focus on automation and data-driven decision-making.
Successful pilot
Spanish fuel distributor Propenor, a subsidiary of Cobo Tankers and Services Ltd, adopted the NivelWatcher system following a successful pilot project.
“We started with five sensors and now operate with 50,” said Raúl Blanco, Sales Representative at Propenor. “We previously depended on customer calls and our estimates. Now we have real-time visibility, which improves planning, reduces costs, and enhances customer satisfaction.”
The NivelWatcher system is low maintenance, with low power requirements, and is scalable for fleets of any size. It aims to provide distributors with tools to modernise fuel delivery operations while maintaining reliability and responsiveness to customer needs.
