Abstract
The paper describes a high precision gas meter suitable for low rates of flow (< 5 cm3 min-1) which can be interfaced with data acquisition software for continuous on-line measurement. The meter used the highly sensitive pressure transducers currently available, operated with a very small back pressure, and had an accuracy around 0.5%. A frequency to voltage converter was developed and built into the gas meter. This allowed direct connection to a data logger/computer without prior computation.
