Contact SupplierBROILTECHÂ Thermal mass flow meter for detection and metering the gas and air. Its work on principal of calorie amount taken away from the heated sensor by a fluid flow is calibrated to the mass of flow,
Â
Thermal mass flow meter use for measuring : air, nitrogen, argon, co2, chlorine, ethane, ethylene, methane, ammonia, helium, hydrogen, bio gas,
 Thermal mass gas flow meter
