Allengra's Hydrogen Flow Meter is designed to support emerging UAV platforms that utilize hydrogen fuel cell propulsion systems, providing accurate measurement of hydrogen flow for monitoring and analysis. By tracking flow rates and hydrogen consumption during flight, the sensor enables developers and operators to optimize system performance, evaluate efficiency and support operational planning for fuel cell-powered unmanned aircraft. Utilizing ultrasonic measurement technology, it delivers reliable flow sensing without moving parts.
The sensor features a robust stainless steel 316L construction and integrates temperature, pressure and humidity sensing into a single compact unit. This multi-parameter approach allows multiple operating conditions to be monitored simultaneously while reducing overall system complexity. CANbus and Modbus interfaces provide straightforward integration with onboard electronics and control systems, enabling hydrogen flow data to be incorporated into vehicle monitoring and telemetry.
