The invention relates to an automatic trifluoromethanesulfonic acid filling system and method, and belongs to the technical field of product filling. The feeding port of a filling barrel is connectedwith a normally open port of an automatic three-way valve; the other two ports of the automatic three-way valve are respectively connected with a feeding pipeline and a discharging pipeline, and the two ports are opposite in opening and closing state when the automatic three-way valve is used; a filling pipe is led out from the bottom of an acid storage tank from bottom to top and then connected with the feeding pipeline, the outlet at one end of a balance tank is connected with the discharging pipeline through a pipeline, and the outlet at the other end of the balance tank is connected with an air suction port of a vacuum pump through a vacuum pipe; a control module controls the port connected with the feeding pipeline in the automatic three-way valve to be communicated with the normallyopen port for filling; in
