Gas Flow Controller & Air Mass Flow Meter – Precision Gas Flow Measurement Solutions MN112892

The Gas Flow Controller & Air Mass Flow Meter offers precise measurement and control of gas flow for various applications, including nitrogen, natural gas, argon, CO2, and more. Utilizing thermal mass flow technology, this device measures gas flow by detecting the amount of heat removed by the gas as it passes through the sensor.

With two temperature sensors—one for reference and one as a heating element—the system adjusts energy input to maintain a stable temperature difference, ensuring accurate mass flow readings. The higher the gas flow, the more heat is dissipated, requiring more energy to maintain this temperature difference, providing precise real-time data on the gas flow rate.

Ideal for monitoring gases such as oxygen, nitrogen, hydrogen, chlorine, and mixed gases (e.g., blast furnace gas, flue gas, biogas, compressed air, natural gas), this device is versatile across industrial applications.
