The invention provides a micro-pressure pipeline delay time measuring system and method, and the system comprises a vacuum environment simulation device, a pressure signal generation device and a control device which are in communication connection, and an FADS pressure measuring pipeline, an acquisition system and a processing system which are in communication connection in sequence. The vacuum environment simulation device is used for simulating environment pressure at different flight heights; the pressure signal generation device is placed in the vacuum environment simulation device and is used for generating dynamic pressure signals with various amplitudes and frequencies under the control of the control device; the FADS pressure measuring pipeline comprises a main pipeline communicated to the surface of an aircraft, a first branch connected with an absolute pressure sensor and a second branch connected with a differential pressure sensor, wherein the first branch and the second branch are communicated with the main pipeline. And the acquisition system is in communication connection with the absolute pressure sensor and the differential pressure sensor. According to the embodiment, the processing system determines the Mach number according to the first branch, selects the corresponding branch according to the range of the Mach number, and determines the delay time.
