Sentronics is the global leader in portable ultrasonic fluid flow monitoring technology, delivering highly accurate real-time fuel consumption measurement solutions tailored to the demanding requirements of the UAV industry.
Unmanned Systems Technology (UST) is pleased to announce the addition of Sentronics to our global supplier ecosystem. As a Silver Supplier, the company is showcasing its advanced ultrasonic flow measurement technology, developed to provide UAV manufacturers and operators with highly accurate fuel monitoring and engine performance data.
Originally homologated for use in world-leading motorsport championships, Sentronics’ technology has been specifically adapted for unmanned aerial vehicle applications, enabling commercial and defense drone platforms to dynamically calculate range and endurance with exceptional precision. By delivering real-time fuel consumption rate and total consumed fuel mass/volume data with ultra-low latency, the company’s solutions help operators optimize mission planning, improve fleet efficiency, and predict maintenance requirements through long-term engine performance analysis.
Key features and benefits of Sentronics’ UAV fuel flow monitoring technology include:
High-Accuracy Measurement – Industry-leading precision with accuracies better than ±0.75% of reading, ensuring dependable mission-critical data.
Compact & Lightweight Design – Low-SWaP sensors weighing typically less than 150g minimize impact on payload capacity and platform performance.
True Multi-Fuel Capability – Consistent, high-precision operation across gasoline, kerosene, diesel, Jet-A1, and JP fuels without recalibration.
Zero Pressure Drop – Non-intrusive ultrasonic sensing eliminates flow restriction and maintains engine efficiency.
Advanced Connectivity & Diagnostics – Support for CAN, DroneCAN, and TTL protocols alongside integrated data logging, remote bootloading, and sensor health monitoring.
Ruggedized Construction – Designed to MIL-STD-461G, DEF-STAN 59-41, and RTCA-DO-160G standards with IP67 protection for reliable operation in harsh environments.
Sentronics’ flagship RealFlow® D-Series ultrasonic flow meters have been engineered specifically for UAV and unmanned systems integration. Featuring an innovative inline architecture and patented anti-aliasing technology, the sensors accurately quantify even highly dynamic fuel flows while integrating seamlessly into a broad range of airframes.
Available in multiple configurations, including models for 4.5 and 6mm bore internal diameters, the RealFlow® D-Series supports a wide range of fuel flow requirements for platforms ranging from small tactical drones to heavy-lift cargo UAVs. The rugged sensors also feature standard aviation fittings and extensive onboard diagnostics, making them ideal for demanding operational deployments.
