Abstract: The method, called pressure stimulation by gas injection, was introduced in detail for the measurement of liquid propellant residue on the national satellite. A technical scheme in practice was given. The conclusion that the measurement accuracy for liquid propellant residue volume attains to 1 % of the total tank volume was obtained with total error analysis and suitable correction.
