핵심적인 기술적 이점
-
Fiscal Hydrogen Accuracy: The FLOWSIC610 is among the few ultrasonic meters globally certified to meet Accuracy Class 1 standards for hydrogen custody transfer. This ensures that financial transactions between producers and grid operators are based on legally compliant, high-precision data.
-
Real-Time Purity Monitoring: A unique feature of the FLOWSIC610 is the integrated hydrogen purity indicator. By continuously monitoring the speed of sound, the device can detect contamination or changes in gas composition instantly, offering a layer of process control without expensive external analyzers.
-
High-Velocity Performance: Hydrogen applications often require high flow rates to maintain throughput. The FLOWSIC610 is proven to maintain its fiscal accuracy at gas velocities up to 60 m/s (200 ft/s), allowing operators to maximize pipeline capacity.
-
Energy Efficiency (Zero Pressure Drop): The ultrasonic transducers are mounted outside the flow stream, creating a completely unobstructed full-bore design. Unlike orifice plates or turbine meters, it creates no pressure loss, significantly reducing the energy costs associated with gas compression.
-
Extreme Turndown Ratio: With a turndown ratio of 1:160, the meter handles the highly variable output characteristic of green hydrogen electrolyzers, which often fluctuate based on the availability of renewable energy sources.
-
Future-Proof for Clean Energy: The device is designed to handle pure hydrogen as well as hydrogen blends, making it a versatile asset for existing natural gas grids transitioning to “H2-ready” status.
