Jack Birmingham, Senior Engineer at Reventec, recently engaged with UnmannedSystemstechnology.com to explore the significance of fuel level sensing in UAVs and highlight the unique features of Reventec’s sensors.
A range of UAV capacitive liquid level sensors.
What are the primary benefits of integrating fuel level sensing in UAVs?
The foremost benefit of incorporating a fuel level sensor in unmanned aerial vehicles (UAVs) and other uncrewed platforms is the ability to accurately gauge the amount of fuel available. This precise knowlege empowers UAV operators to make informed decisions and allows manufacturers to design UAVs with enhanced range capabilities.
As the applications for advanced UAVs expand—ranging from surveillance and reconnaissance to agricultural monitoring and defense—the need for accurate fuel level assessment in fuel-powered UAVs is increasingly critical.
Why are capacitive liquid level sensors superior for UAV applications?
LMS100-MICRO Liquid Level Sensor.
Selecting the appropriate liquid level sensing technology is crucial for optimal request performance. We assert that capacitive liquid level sensors are the most suitable choice for most UAV applications due to their solid-state design, resistance to vibration and shock, and high measurement accuracy, which ensures reliability.
Our capacitive sensors can be installed at any angle, making them ideal for hard-to-reach fuel tanks, as they are not affected by physical orientation. In contrast,traditional float switch sensors,frequently enough used in industrial settings,have moving components that require maintenance and may lose accuracy in dynamic environments where liquid movement occurs.Reventec’s capacitive sensors are lightweight, robust, and proven to perform reliably in extreme conditions.
What distinguishes Reventec from other liquid level sensor manufacturers?
Reventec specializes in creating customized, high-performance sensing solutions. Unlike some competitors who provide generic products that require customers to adapt their fuel tank designs to fit sensor dimensions, we understand the importance of tailored sensors for low-volume and specialized projects. Our collaborative approach allows us to manufacture sensors that meet specific length, shape, and mounting requirements for each application.
The LSM500-CONTOUR features a custom contour design.
Our UK-based manufacturing facility is co-located with our design and growth office, enabling us to create bespoke capacitive liquid level sensors like the ultra-lightweight LSM100-MICRO and the LSM500-CONTOUR. The LSM500-CONTOUR, for instance, was designed to match the contour of an existing oil dipstick, providing a seamless replacement for a defense client. This upgrade to a smart oil level sensor that monitors levels in real-time has streamlined vehicle inspections, reducing the need for daily manual checks and ensuring readiness for rapid deployment.
Whether clients require sensors designed to fit unique spatial constraints, measure irregularly shaped tanks, or access fuel tanks in arduous locations, Reventec develops measurement devices that can be installed in any orientation for convenient placement and accessibility.
additionally, all our capacitive liquid level sensors are calibrated in the specific fluid they will measure, rather than just water. This tailored calibration enhances precision, achieving an accuracy of ±0.5% of the reading.
Our technology also adheres to various MIL-STD-461F and RCTA DO160F EMC standards, ensuring compliance with military specifications and suitability for a wide range of defense applications.
Can you share any notable case studies with our audience?
The LS200 Fuel Level Sensor installed in the Alpha 900 fuel tank.
Due to the sensitive nature of many projects, we cannot disclose all the platforms we support. however, we are proud to mention that Alpha Unmanned Systems utilizes our 2-bolt fuel level sensor in their Alpha 900, a compact military-grade uncrewed helicopter. The Alpha 900 was showcased at DSEI this year, demonstrating the integration of our liquid level sensors.
We continue to supply several defense UAV platforms, including Shield AI’s V-BAT (formerly known as Martin UAV). more details can be found in our case study: Advanced Fuel Measurement Technology Used on V-BAT Tactical UAS.
what is the future of this technology?
We are continually advancing our technologies based on customer feedback and emerging market demands. Our capacitive liquid level sensing technology is highly adaptable,and we are consistently enhancing the features we offer.
In our product development roadmap, we plan to introduce additional output options, including configurable Pulse Width Modulation (PWM) outputs, and we are working on the DRONECAN protocol, which will be available to customers in the coming months.
