Mass flow instruments play an important role in every CVD application. This paper will describe the basic characteristics of thermal mass flow metering and controlling of gases and liquids. The essential theoretical background will be given as well as information provided by the leading manufacturer in Europe. Also some practical uses of the instruments in CVD applications will be highlighted. With high accuracy and very good reproducibility the instruments are very well suited for the key role of controlling the fluids (gases and liquids) in CVD applications.
