First of all, we should understand the principle of gas mass flowmeter:
Thermal gas mass flowmeter is an instrument for measuring flow based on heat conduction principle. The instrument adopts constant temperature difference method to accurately measure gas mass flow. The sensor part consists of two reference platinum resistance temperature sensors. Using a bridge loop, one sensor measures the fluid temperature, and the other sensor maintains a constant temperature difference higher than the fluid temperature.
It can be seen that the influence of heating is very important for accurate measurement of flow.
In practical production and application, the medium we measure often contains water and water molecules, which will directly affect the heating effect. Therefore, the factors affecting the gas mass flowmeter are determined by the humidity of the medium.
I recommend you to know about the gas mass flowmeter produced by Jiangsu Dongxiang Instrument, which can effectively prevent water molecules from clustering on the sensor, and the chip in the sensor can effectively deal with the phenomenon of water molecules clustering. Therefore, the gas mass flowmeter produced by this factory can measure wet media.
The other is the installation factor. If installed, it needs straight pipe sections before and after, with the first ten and the last five.
Then there is the quality problem of the manufacturer, so I won't say much about it.
