Reventec is at the forefront of developing advanced sensing solutions for the unmanned sector, with a strong focus on reliability and adaptability.
In this Q&A, Senior Engineer at Reventec, Jack Birmingham, discusses the latest advancements in the company’s capacitive fuel level sensor technology, including the integration of DroneCAN for streamlined system compatibility, enhanced customization for complex fuel tank designs, and robust performance in high-vibration environments.
Ahead of their participation at DSEI 2025, Reventec also highlights upcoming innovations, customer support initiatives, and the vital role the event plays in connecting with UAV and VTOL developers worldwide.
Can you tell us about the latest advancements in Reventec’s capacitive fuel level sensor technology for UAVs and VTOL unmanned helicopters?
We’ve seen significant advancements in our capacitive fuel level sensor technology, particularly in response to the evolving needs of the UAV market. A key development is the integration of the DroneCAN protocol which we will be formally launching at DSEI.
This is a game-changer for many of our customers, as it provides a robust, reliable, and standardised communication interface that simplifies integration with flight controllers and other onboard systems. We’ve also enhanced the customisation options available, allowing us to tailor sensor designs to the unique and often complex geometries of UAV fuel tanks. This includes custom probe lengths, mounting configurations, and connector types.
Your sensors are designed for harsh and high-vibration environments. How do you address the unique challenges presented by VTOL platforms and long-endurance UAVs?
Our capacitive liquid level sensors employ solid-state technology, which is fundamental to their real-time, reliable performance under harsh conditions. The absence of any moving parts means they are inherently immune to the high-frequency vibrations and shock loads typical of UAV and VTOL platforms.
For long-endurance UAVs, where reliability over thousands of flight hours is critical, this solid-state design is a major advantage. Our sensors are also fully sealed and constructed from durable materials including robust aluminium and lightweight carbon fibre, providing excellent resistance to fuel contamination, corrosion, and pressure changes. In addition to our sensors being EMC certified, we continuously conduct rigorous in-house vibration and environmental testing to ensure our products meet the demanding standards of the defence sector.
How does Reventec support developers and integrators during the implementation of your fuel sensors?
Our primary goal is to make the integration process as seamless as possible. Our sensors are designed for plug-and-play functionality. A key part of this is our factory calibration process. We conduct fluid calibration of all our liquid level sensors in our factory using the intended liquid (e.g., AVGAS, Jet A-1, Diesel). This means our customers receive their sensors ready to install, pre-calibrated for their specific application, eliminating the need for complex and time-consuming on-site calibration. We also provide comprehensive technical documentation, CAD models, and direct engineering support to assist with everything from initial design integration to post-installation queries.
What can visitors at DSEI 2025 expect to see from Reventec in terms of new or enhanced solutions for the unmanned sector?
We are excited to be returning to DSEI this year. We will be launching a new technology that will be an excellent accompaniment to our capacitive liquid level sensors for UAV applications. This new product is designed to further enhance fuel system monitoring and efficiency. While I can’t reveal all the details just yet, I can say that it will provide a new layer of data and insight for flight operators.
Stay tuned for an official announcement and global product launch at DSEI. We believe this new offering will be a significant step forward for the unmanned sector.
How important is DSEI for your engagement with defense and aerospace OEMs in the unmanned systems space?
DSEI is an important event for us as it provides a great backdrop to meet with long-standing customers, strengthen our relationships, and discuss new project requirements. Simultaneously, it allows us to significantly increase the visibility of our versatile products to other airframe manufacturers, engine developers, and ground vehicle component engineers.
The unmanned systems space is a key focus area for us, and DSEI provides an unparalleled opportunity to showcase how our robust, reliable, and highly customisable sensors can solve some of the most challenging fuel and fluid management problems in this sector. Visit us at stand N5-155 to discover our new products and chat through your sensor requirements with one of our engineers.
Thank you for your time, it’s always great to talk to Reventec and we look forward to providing more coverage on your liquid level, position and flow sensors.
