Abstract: A vacuum mass flow control apparatus and a control method thereof. The apparatus includes: a housing; a first flow channel disposed in the housing and having a first starting end and a first terminating end; a first sensor for collecting a signal of fluid in the first flow channel; a second flow channel disposed in the housing and having a second starting end and a second terminating end; a second sensor for collecting a vacuum flow rate in the second flow channel; a venturi tube having an inlet end, an outlet end and a negative pressure suction port; a regulating valve for regulating a flow-through cross-sectional area of the first flow channel; and a controller electrically connected to the regulating valve, the first sensor and the second sensor. The present disclosure improves structural integration, greatly reduces structural volume, and realizes real-time precise regulation in terms of control.
