For example, a production line may currently measure compressed air but later switch to nitrogen. A wastewater treatment plant may need to monitor biogas today and natural gas in the future. Some laboratories even alternate between argon, carbon dioxide, and oxygen during different processes.
Although using a single flow meter for multiple gases seems convenient and cost-effective, the answer is not as simple as “yes” or “no.” The suitability depends on the operating principle of thermal mass flow measurement, the gas properties, and whether the instrument supports multiple gas calibrations.
This guide explains why gas selection matters, when one meter can measure different gases, and how to ensure accurate measurements in multi-gas applications.
