進(jìn)口熱式氣體質(zhì)量流量計(jì)產(chǎn)品用途 Product use進(jìn)口熱式氣體質(zhì)量流量計(jì)是利用流體流過(guò)外熱源加熱的管道時(shí)產(chǎn)生的溫度場(chǎng)變化來(lái)測(cè)量流體質(zhì)量流量，或利用加熱流體時(shí)流體溫度上升某一值所需的能量與流體質(zhì)量之間的關(guān)系來(lái)測(cè)量流體質(zhì)量流量的一種流量?jī)x表。無(wú)須壓力、溫度補(bǔ)償，就能方便地檢測(cè)在管道中流動(dòng)的天然氣、空氣、氫氣、氧氣、氯氣、氮?dú)�、氬氣、氨氣、沼氣、煤氣、煙道氣（除乙炔氣）等氣體的質(zhì)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
