- 23 Aug 2010
TL;DR: A mass flow controller comprises a flow rate measuring part that measures the flow rate of a fluid flowing in a flow channel and outputs a measured flow rate value, a control valve, a valve control part that controls an opening degree of the control valve based on an entirely-close command to entirely close the valve compulsorily or a set flow rate values set as a target value.
