The insertion gas mass flow meter uses standard precision wind tunnel calibration and adopts the King's law of thermal dissipation (cooling) effect based on the constant temperature principle. It can simultaneously display flow rate (flow), and temperature. It is sensitive to low flow rates and achieves high accuracy at high flow rates. Even at high temperatures, it can achieve good constant temperature difference and good stability.
It can measure various gases, directly outputting mass flow rate without temperature and pressure compensation. It is available in intrinsically safe and explosion-proof types, with two output options. Suitable for large-diameter, low-flow measurements, with multiple installation methods available.
Measured media: Air, natural gas, biogas, coal gas, dry chlorine, oxygen, carbon monoxide auxiliary fuel, flue gas, torch gas, hydrogen, argon and other dry gases.
