2,647 km per kilogram of hydrogen are no coincidence

Precision that makes efficiency measurable

At the Shell Eco-Marathon 2025, the Ecogenium team’s hydrogen prototype vehicle Hydraix II achieved an outstanding range of 2,647 km per kilogram of hydrogen, securing second place worldwide.

✅ A key contributor to this success: precise and reliable flow measurement.

The red-y smart series mass flow meter was integrated directly into the hydrogen supply system, delivering high-quality real-time measurement data—even under the most demanding conditions.

What makes the difference?
The red-y smart series is designed for applications where extremely low flow rates, rapid load changes, and limited installation space are the norm rather than the exception:
▶️ Reliable measurement even at very low flow rates
▶️ Fast response times for dynamic processes
▶️ Stable, drift-free measurement results, even at elevated temperatures
▶️ Compact design for easy system integration

Thanks to consistently high data quality, consumption, control strategy, and driving profile could be specifically optimized. Flow measurement thus evolved from a simple measurement point into a strategic optimization tool.

The red-y smart series demonstrates what is possible when measurement technology is uncompromisingly focused on performance.

For developers and system integrators, this means: greater efficiencygreater control, and measurable results—even in highly dynamic hydrogen applications.
