The Hydrogen (H2) ST Series flowmeters deliver exceptional accuracy with a 100:1 turndown ratio, accommodating flow ranges from 0.25 to 1,000 SFPS (0.07 to 305 NMPS). Designed for hydrogen applications, these meters ensure reliable performance in industrial and energy sectors, including fuel cells, refineries, and gas distribution systems.
Flexible Installation and Power Options
With integral or remote transmitter mounting options—extending up to 1,000 feet (305 meters)—the H2 ST Series offers versatile deployment in complex setups. Available in DC- or AC-powered versions, these flowmeters provide seamless integration into diverse operational environments, ensuring compatibility with both stationary and mobile systems.
Advanced User Interface and Communication
Equipped with an LCD touchscreen, the H2 ST Series displays real-time flow rates and totalizer data, enhancing user interaction. Supporting digital bus communications—including HART, Modbus, Foundation Fieldbus, and Profibus—the meters enable seamless data exchange with control systems, facilitating automated monitoring and process optimization.
Rugged Design for Hazardous Environments
Built to withstand harsh conditions, the flowmeters feature NEMA 4X/IP67-rated enclosures in aluminum or 316 stainless steel. Certified for Intrinsically Safe (IS) Division 1/Zone 1 environments, they meet global safety standards, ensuring long-term durability in explosive or corrosive atmospheres.
Reliable Performance for Critical Applications
Combining precision measurement with robust construction, the H2 ST Series is ideal for hydrogen processing, storage, and transportation. Its advanced diagnostics and communication capabilities make it a trusted solution for industries demanding high accuracy, safety, and operational efficiency.
