| The definition of a “no flow” condition is that the pressure on the inlet side of the MFC is equal to the pressure on the outlet side of the MFC control valve. Whether the MFC is at atmospheric pressure, vacuum pressure, or process pressure, the zero should not be initiated until the pressure differential across the MFC is zero. | The definition of a “no flow” condition is that the pressure on the inlet side of the MFC is equal to the pressure on the outlet side of the MFC control valve.
