Flow rates are generally categorized into two types: 'volume flow rate' and 'mass flow rate'.
The volume flow rate is affected by environmental factors such as temperature and pressure, causing the flow amount to vary with changes in these conditions.
Consequently, volume flow rate is not suitable for applications requiring precise flow control.
In contrast, mass flow rate remains consistent regardless of environmental changes, making it ideal for accurate flow control.
Due to its reliability and precision, mass flow rate is widely used in semiconductor and display processes, as well as in industries like oil refining, chemicals, iron making, and medical care.
