GM Flow are experts in measurement of the flow rate of gases, historically natural gas and nitrogen, but now we excel in hydrogen and CO2. Our technology is designed and built in Scotland, with over 100 years of experience within our team. With less than 1 bar pressure-loss, and no moving parts, our latest product Hy-Cone™, is designed specifically for Hydrogen. The low-pressure loss across Hy-Cone™ maximises hydrogen throughput in vehicle fueling applications. For electrolyser applications, these devices monitor hydrogen output rates, maintaining maximum electrolyser efficiency over time.
