How should the gas flow rate of the thermal mass flow meter be calculated? What are the calculation methods? Generally, when ordering a thermal gas mass flow controller, you will confirm the specific flow rate and specific parameters such as which gas to use. There are many ways to express the mass flow of gas, which can be converted by mass, density, volume, etc. The value measured by a general thermal gas mass flow controller/mass flow meter is the mass flow, and the user does not need to do any conversion. , The measured value does not need to be converted for temperature and pressure compensation.

 

The thermal mass flow controller/mass flow meter adopts professional technology to ensure the consistency and reliability of the instrument through the analysis of the two principles. The meter has two sensors, one is the heat source and the other measures the temperature of the medium. When the fluid flows, the molecular weight of the fluid flowing through the two sensors is proportional to the heat loss of the heat source. Therefore, we can calculate the fluid flow rate through the electronic module.

 

Because of its unique advantages, thermal gas flow meters are suitable for various working conditions in various industries. It can be applied from vacuum to high pressure working environment, and the flow rate is not affected by temperature and pressure.
