Flow: Single gas flow

Oxygen, Hydrogen, Carbon dioxide, Nitrogen and Argon are the most commonly measured single gases in industry.

Mass gas flow measurement has a greater advantage over volumentric measurement since it is unaffected by pressure and temperature variations.  Flow monitoring of feed lines can prevent unsafe conditions that may arise when gas supply is insufficient.  It is also usefull when centralized facilities bill the individual plants for gas usage.  Oxygen flow increases combustion temperatures in open hearth and blast furnaces.  Consideration must be given to Hydrogen’s volatility and its greater cooling effect on the sensor compared to other gases. Retractable probe assemblies allow the installation of the instrument in applications which must remain in continuous operation and in different pipe diameters.
