Cryogenic Meter Provers for LNG Service
Product Temperatures Down to -320oF (-195oC)
Flow Management Devices is advancing LNG custody transfer measurement with their LNG cryogenic meter proving technology. FMD offers a complete line of small volume provers which incorporate our cutting-edge prover and material technology to ensure optimal performance in the extreme low temperatures characteristic of LNG environments. FMD small volume meter provers can be customized with options specifically designed to prove flow meters in liquified natural gas (LNG) process conditions. Our LNG line of provers operates seamlessly down to -320°F (-195°C), a temperature commonly encountered during LNG ship loading and offloading.
FMD meter provers significantly reduce measurement uncertainty compared to traditional LNG verification methods. Discover the future of precise LNG measurement with FMD’s comprehensive line of meter provers.
