Hydrogen Flow Meter micro Hy-Orifice™ LP (12mm)
- Built entirely from 316L SS, micro Hy-Orifice provides a tough, accurate, corrosion and erosion-resistant flow measurement technique, which is easy and safe to operate, even by inexperienced personnel.
- Utilises NPT Threaded end connections and offers a flow range which is changeable by offering 4 to 8 mm orifice sizes.
- Hy-OrificeTM offers a quick, easy, and compact installation with a flow computer, differential and flowing pressure, and temperature transmitters already included as options, ready to measure any flow rate within the ranges quoted.
- Hydrogen flow meter micro Hy-Orifice includes differential pressure flowing pressure ports, built into the meter body.
- By varying the orifice size, differential pressure, and flowing pressure transmitter ranges, micro Hy-Orifice™ HP can measure from as low as 0.18 g/sec (@ 5 Bar) up to 80 g/sec of Hydrogen (@ 340 bar). micro Hy-Orifice™ complements our micro Hy-Cone™ and Integra-Cone™ flow meters by providing a very low flow range device for medium pressure applications.

GM Flow Measurement Services
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.
