OVAL Corporation, headquartered in Japan and manufacturing high-quality Coriolis mass flow meters since 1985, has been at the forefront of hydrogen flow measurement since the late 1990s, addressing the unique challenges of this evolving market with flow measurement solutions specifically designed for hydrogen applications. The company's Super High-Pressure Coriolis Flow Meter, designed to meet the needs of hydrogen applications, offers exceptional pressure handling up to 120 MPa (1,200 bar) making it ideal for high-pressure hydrogen systems, versatility for measuring both liquids and gases, and high accuracy delivering precise readings within plus/minus 0.5% for mass flow rates above 9.6 kg/h and plus/minus 0.125% for lower flow rates, constructed from hydrogen-resistant materials including TPXM-19 UNS S20910 for wetted parts and SUS304 for the housing to ensure long-lasting durability. OVAL's flow meter is specifically designed for applications including hydrogen filling and loading systems (static and dispensing systems for vehicles and industrial use) and emerging hydrogen economy infrastructure supporting hydrogen-powered vehicles and energy systems, featuring forward and reverse flow measurement, explosion-proof configurations (TIIS, ATEX, IECEx certifications), and a choice of communication protocols perfectly suited for the demands of the hydrogen market. The company's FHA and FHD series (gas flow meters with hydrogen-proof structure modifications) and broader Coriolis, thermal, positive displacement, and vortex flow meter portfolio spanning general industrial gas measurement, complements its dedicated hydrogen product line, with OVAL Corporation continuing to develop precision flow measurement technology essential for hydrogen filling stations, refueling infrastructure, and the broader emerging hydrogen economy worldwide.
