Thermal Mass flow meter for Gas measurement

Coriolis and Thermal Flow Meters measure mass flow through how thermal flow meters take measurements is quite different. They use heat conducting properties rather than fluid momentum which is used by Coriolis. Some thermal dispersion flow meter can measure liquid flow although most of them measure gas flow.

Hotwire anemometers which contain heated thin wire were used in turbulence research and velocity profile. They are fragile and small hence they are susceptible to dirt and breakages that is why it is not recommended for industrial use.

 

Various technologies have been used for thermal Flowmeters. This is why some measures temperature difference between ambient flow stream and heated sensors. Others measure the speed of heat added to flow stream disperses. Therefore, Thermal Flow Meters require more than one temperature sensors so that it can measure the fluid temperature at integral points.

 

Just like the other Flowmeters, it has its advantages and disadvantages. Well, it is good for those who are under a tight budget because of the low purchase cost. Additionally, they can measure the flow of low-pressure gases that is what makes it more unique.

 

However, it offers low medium accuracy though there are improvements on this to make it more accurate.
