Gas turbine flow meters are extensively utilized across diverse industrial sectors for precise measurement of various gaseous or air media. In the petroleum and petrochemical industry, these gas flow meters accurately measure natural gas (primarily methane CH₄), hydrogen (H₂), and carbon dioxide (CO₂) in refineries and processing plants. The power generation sector relies on them for monitoring natural gas (CH₄) and hydrogen (H₂) consumption in turbines and fuel cells.
Chemical manufacturing facilities employ these gas flow sensors for measuring nitrogen (N₂), oxygen (O₂), and various inert gases like argon (Ar) and helium (He) in production processes. The steel and metallurgy industry utilizes them for monitoring oxygen (O₂), nitrogen (N₂), and argon (Ar) flow in furnaces and metal processing applications.
Pharmaceutical and biotechnology companies depend on these meters for precise measurement of nitrogen (N₂), carbon dioxide (CO₂), and compressed air in sterile manufacturing environments. The food and beverage industry uses them for monitoring carbon dioxide (CO₂) and nitrogen (N₂) in packaging and preservation processes.
Environmental monitoring applications include measuring methane (CH₄) emissions from landfills and biogas (CH₄, CO₂, H₂S) from waste treatment facilities. Research laboratories utilize these gas flow meters for controlling flows of specialty gases including hydrogen (H₂), helium (He), and various calibration gas mixtures for analytical gas flow instrumentation and experimental procedures.
