Analysis of advantages and disadvantages of thermal gas mass flowmeter

Advantage:
1. It can be used to measure the small flow rate at low flow rate. The immersion type can also measure the medium high flow rate. The plug-in thermal gas mass flow meter can also measure the flow rate of large diameter.
2, no moving parts, simple installation, no obstruction, small pressure loss, and no need to compensate for temperature and pressure can directly measure the mass flow of the fluid. The most prominent is the wide range, high precision, and easy operation, which reduces a lot of unnecessary troubles in the process of use.
3, the use of relatively reliable performance, compared with other types of mass flowmeters, does not require temperature sensors, pressure sensors and computing units, its composition is relatively simple, easy to operate, stable, and high accuracy.
insufficient:
1. When using a thermal gas mass flow meter to measure small flows in an application, the meter will bring considerable heat to the gas being measured, which makes the meter less accurate in measurement.
2, split type thermal gas mass flowmeter, if the measured gas affects the measured value in the fouling layer of the pipe wall, it must be cleaned regularly; the pipe type is easy to appear when the pipe is in use, in practical application it Generally it cannot be used.
When using a thermal gas mass flow meter, people should make full use of its characteristics, and at the same time be good at circumventing its deficiencies, so that it will receive better results in practical applications.
