MFT-20
Mass flow checker
When there is a suspected problem with a mass flow controller, it is
necessary to check the power source, display unit, settings unit,
cables, and SEC itself for malfunctions, in order to determine
the cause of the problem. The MFT-20 can drive the SEC and monitor
its input and output voltage, while carrying out the necessary control
functions to determine if the SEC is operating properly. This allows
the user to determine if the source of a problem is the SEC itself or
the power source, before detaching the SEC from the equipment
piping. An internal potentiometer enables control of the SEC as well.
sEnables easy checking of the mass flow controller without detaching
the piping connections.
sNo power source required.
sCan open and close the valve.
sAuto-zero function is available (only for the SEC, which features
an auto-zero function).
