Abstract	The development of a liquid oxygen density reference system is used in the measurement of liquid oxygen density. The system consists mainly of liquid oxygen container, special purpose thermostat, pressure control device, buoy, evacuation system, electronic balance measurement system, tracking and commanding system of chip microprocessor, and PC. The analysis of measurement uncertainty for the liquid oxygen density reference system indicates that the system error is /spl plusmn/0.02%. In the light of random error possibly resulting from measurements, the measurement uncertainty of liquid oxygen density for the system is /spl plusmn/0.05%. The measurement of liquid oxygen density will be more correct, reliable and convenient for the liquid oxygen density reference system, when compared with sensor of traditional liquid oxygen density measurement.
