The invention relates to an electronic automatic verification device for soap film flow. The problem that output of an existing verification device is unstable and an original record of detection cannot be automatically generated is effectively solved. According to the technical scheme, the device includes an automatic stabilization gas source system, a pipeline system, a data acquisition and control system, and an upper computer verification software system; the automatic stabilization gas source system includes a gas source, one end of the automatic stabilization gas source system is communicated with a gas-liquid separator, the other end of the gas-liquid separator is communicated with a precise pressure regulating valve, the other end of the precise pressure regulating valve is communicated with a solenoid valve, the other end of the solenoid valve are communicated with three mass flow controllers with different flow ranges respectively, and the three mass flow controllers with different flow ranges refer to the small mass flow controller, the middle mass flow controller and a big mass flow controller. The other ends of the three mass flow controllers are communicated with buffering tanks with different volumes respectively, and the three buffering tanks are communicated with an air outlet. The output of the device is stable and the practicability is high.
