Product Overview
9ER-800S thermal gas mass flow meter is the principle of measuring thermal conductivity of gas mass flow meters, different from other gas flow, pressure and temperature correction does not require a direct measurement of gas mass flow. Wide range of applications: oxygen, nitrogen, hydrogen, chlorine, and multi-component gases （excluding acetylene）, blast furnace gas, coke oven gas, flue gas, methane, water treatment aeration and chlorine, compressed air, natural gas, liquefied gas, flare gas, wind power plants at a blast furnace, secondary air, the mine ventilation or exhaust system flow measurement.
