    摘要： Ullage volume of a container containing a fluid is determined by injecting a known quantity of radioactive material into the ullage volume. After the radioactive material has dispersed uniformly throughout the ullage volume the density thereof is measured to provide the ullage volume indication. The system can be utilized to monitor the amount of fuel in the container under either zero G or a gravitational field. The ullage volume indication can be compensated for pressure variations within the volume by utilizing a pressure transducer having an output that is combined with the detected density. A system is provided to compensate for background, radiation noise. The system can also be utilized to detect leakage from the container by noting changes in concentration of the radioactive material. Corrections for temperature variations are also provided. In fixed volumes systems, the device can be utilized to monitor pressure and temperature variations.
