What are the advantages and disadvantages of thermal gas mass flowmeters?
2022-07-12
Thermal gas mass flowmeter mainly uses the principle of heat dispersion to detect the surface of gas flow, and to detect natural gas, liquefied gas, flare gas, etc. In this case, what are the advantages of thermal gas mass flowmeters? Let me tell you.
1.Thermal gas mass flowmeter response slow Thermal gas mass flowmeter response is slow, the steady state value is generally in 2~5s, the faster is 0.5s, some structural types last more than ten seconds to tens of seconds.
2. The adjustment of the mixture also has an impact on the mass flow measurement of the thermal gas mass flowmeter. There is a large adjustment of the detected gas components due to cp value and thermal conductivity adjustment, the measured value will have a large adjustment of the fault. For a small flow rate, the surface layer will cause appropriate heat to the measured gas. For a thermal distribution system, if the measured gas precipitated in the tube and affected the measured value, it must be cleaned on time.
3. The pipe that is easy to produce liquid collection is not suitable for the hot gas mass flowmeter of the machine, because the measurement principle of the hot gas mass flowmeter is the application of thermal diffusion technology, that is, the size of the detection signal depends on the cooling speed of the gas, so the pipe that is easy to produce liquid collection is not suitable for the hot gas flowmeter of the machine and equipment in some environments, Inevitably, droplets are attached to the sensing technology head, so the sensing technology head should face up to the machine equipment to prevent the concentrated flow of fluid to the sensing technology head.
4. The thin tube surface layer is more easily blocked, which can not be applied under normal circumstances, and the application of pulse flow will be limited, and the application of viscous fluid is also limited.
