進口熱式氣體質量流量計產品用途 Product use進口熱式氣體質量流量計是利用流體流過外熱源加熱的管道時產生的溫度場變化來測量流體質量流量，或利用加熱流體時流體溫度上升某一值所需的能量與流體質量之間的關系來測量流體質量流量的一種流量儀表。無須壓力、溫度補償，就能方便地檢測在管道中流動的天然氣、空氣、氫氣、氧氣、氯氣、氮氣、氬氣、氨氣、沼氣、煤氣、煙道氣（除乙炔氣）等氣體的質量流量retz Thermal gas mass flowmeter is a flow instrument that measures fluid mass flow using the temperature field changes generated when a fluid flows through a pipe heated by an external heat source, or uses the relationship between the energy required for the fluid temperature to rise to a certain value when heating the fluid and the fluid mass to measure fluid mass flow. Without pressure and temperature compensation, it is convenient to detect the mass flow of natural gas, air, hydrogen, oxygen, chlorine, nitrogen, argon, ammonia, biogas, coal gas, flue gas (excluding acetylene), and other gases flowing in the pipeline
