Sentronics' D-Series ultrasonic flow meters for UAVs offer real-time fuel monitoring capabilities with unparalleled accuracy and low latency, featuring a patented anti-aliasing technique that can accurately quantify even the most dynamic of flows. With a low SWaP profile and a non-intrusive inline design, they can be easily integrated into a variety of platforms, from small tactical drones to heavy-lift cargo UAVs.
The robust IP67-rated sensors offer consistent, high-precision measurement across a wide range of fuel types without requiring recalibration or fuel-specific configuration. Designed to conform to MIL-STD-461G, DEF-STAN 59-41 and RTCA-DO-160G, they can interface with a variety of drone flight controllers via standard protocols such as CAN, DroneCAN, and TTL.
The innovative sensors feature integrated data logging, sensor health checking, and advanced diagnostic data output. They are ideal for use with cloud-based fuel management solutions, offering remote operating system uploads and firmware updates.
