Gas mass flowmeter is a device that can simultaneously measure fluid mass flow rate and temperature. Its working principle is quite clever: by detecting the volume flow rate and temperature of the medium flowing through the sensor, and then multiplying these two values, the mass flow rate of the medium can be obtained.

This type of flowmeter has the advantages of high precision, strong stability, and long service life, so it is widely used in fields such as chemical engineering, petroleum, environmental protection, and scientific research.

Gas mass flowmeter measures flow rate at the molecular level. According to the law of conservation of thermodynamic energy, gas molecules passing through the sensor temperature will change, and the mass flow rate of the gas can be calculated based on the temperature change. The signal measured by the heating sensor is then sent to the signal amplifier for amplification. Compare the set voltage with the amplified flow detection voltage. The difference between the two signals is amplified twice and ultimately controls the regulating valve. Finally, the closed-loop control of the flow rate through the channel is equal to the set flow rate, thereby maintaining the gas flow rate steadily at the artificially set flow rate state.
