Abstract A triple bubbler sensor was developed for use in high temperature molten salt systems used in pyroprocessing to determine the density, surface tension, and depth of the molten salt. Preliminary bubbler testing was performed in aqueous solutions to calibrate and validate the bubbler sensor. Independently determined fluid property values and depths were compared to the calculated values and the percent differences were less than 0.16%, 3.38%, and 0.31% for density, surface tension, and depth, respectively. In addition, uncertainties were within 0.04%, 1.25%, and 0.15% for density, surface tension, and depth, respectively.

使用三重鼓泡器系统准确测定密度、表面张力和容器深度

摘要 开发了一种三鼓泡传感器，用于高温熔盐系统的高温处理，以确定熔盐的密度、表面张力和深度。在水溶液中进行初步起泡器测试以校准和验证起泡器传感器。将独立确定的流体特性值和深度与计算值进行比较，密度、表面张力和深度的百分比差异分别小于 0.16%、3.38% 和 0.31%。此外，密度、表面张力和深度的不确定性分别在 0.04%、1.25% 和 0.15% 以内。
