Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If with gas analysis function
Instruments also analyzing chemical composition go to 9027.
If integrated with automatic flow regulators
Automatic controllers excluded from 9026 by Chapter notes.
If valve flow controller
Principal function as flow control valve classifies in 8481.
