The design and operation are reported of a laboratory-type continuous monitoring system for use in studies of mass flow rates in operating rocket motors. The system consists of a radioactive gamma source and a scintillator detection system using an activated sodium iodate crystal. The factors affecting the performance as related to the data obtained by such a system are discussed. Experimental data are presented in which propellant mass has been plotted against time for a continuously burning rocket motor. Author
