| Abstract: | Monitoring system for cryogenic propellant level used in the ground tests of liquid propellant rocket engine was established. The capacitance level sensor and C-V linear capacitance transmission instrument were the main equipments in this system. A LH2/LOX engine test proved that the system can accurately and rapidly obtain and display the real-time liquid level of the cryo- genic propellant containers. It was also demonstrated that the system operated safely and reliably with high precision, fine repeatability and simple operation. |
