Due to growing concerns about environmental issues such as global warming, liquefied natural gas and liquefied hydrogen are being recognized as promising clean energy sources for efficient transportation and storage. While the demand for liquefied gases is expected to increase in the future, facilities for cryogenic fluid flow testing are scarce internationally. This study aims to develop a cryogenic fluid flow test facility using liquid nitrogen, based on a weighing system and differential pressure control. As a result, at a mass flow rate of 14.2 kg/min, the difference in mass flow rate calculated upstream and downstream was 0.08 %.
