Accordingly, the transmission and reception of data between the host computer and the mass flow controller performed through the optical fiber are not affected by electro-magnetic noise. Further, the mass flow controller can include a correction device responsive to a command from the host computer for correcting the result of a detection, to thereby accurately process the result of the detection because the result of the detection is corrected as required and then transmitted to the host computer as the correct data. | |
