The invention relates to the technical field of measurement, in particular to an in-orbit propellant surplus measuring method for an aerospace metal diaphragm storage tank, which is suitable for measuring the propellant surplus of a metal diaphragm storage tank, namely a pressurized gas and liquid propellant separation structure storage tank, the measuring device is simple in arrangement, the measuring process is convenient, and the measuring accuracy is high. The residual volume of the propellant can be calculated by comparing with a metal diaphragm vertex displacement-liquid cavity residual volume model obtained by a ground test according to the discharge efficiency of the propellant of the metal diaphragm storage tank, so that the high-precision measurement of the residual propellant in the in-orbit full working process of the spaceflight metal diaphragm storage tank is met.
