Endothermic Hydrocarbon Fuel-Tianjin University (EHF-TU) is one advanced propellant and fractionated from RP-3 extensively used in China. The density of propellant EHFTU at supercritical pressures is measured using flow conservation method. The measurement covers the temperature from (303 to 765) K and pressure of (3 to 7) MPa using three tubes with different sizes, and density varies from (759 to 134) kg*m-3. The n-decane is used for calibration and the relative uncertainty of density measurement is 1.1 %. A series of measures were adopted to improve the measurement accuracy including flexible sizes of test tubes, the lumped parameter method and advanced data process. The results indicate that density decreases with the decline of temperature and pressure. Dramatic variation of density occurs in the pseudo-critical region at 3 MPa pressure. Density data is fitted using polynomials and the average absolute deviation (AAD) between the experimental data and fitted data is 0.7%. Additionally, the volumetric thermal expansion coefficient of EHF-TU is calculated using the polynomials.
