This paper describes the design and testing of a computer-controlled sensor for the real-time measurement of the density of a liquid or slurry. It is to be deployed at the US Department of Energy's Hanford Site in Richland, WA, to monitor slurry properties during radioactive waste transfers. To demonstrate the sensor performance, tests were carried out using non-radioactive waste simulants and the results will be presented. The sensor is mounted flush with the pipeline wall in a nominal 5-cm (2-in.) pipe spool piece. The design pressure is 2.8 MPa (400 psi). The probe wedge in contact with the slurry was selected to operate up to pH 14, and the probe components were radiation tested at exposures of 1 x 10(6) R. The sensor is applicable for process control of all types of liquids or slurries in pipelines or in vessels.
本文描述了一种用于实时测量液体或浆料密度的计算机控制传感器的设计与测试。该传感器将部署在美国能源部位于华盛顿州里奇兰的汉福德基地，用于在放射性废物转移过程中监测浆料特性。为了展示传感器的性能，使用非放射性废物模拟物进行了测试，并将给出测试结果。该传感器安装在一个标称直径为5厘米（2英寸）的管道短管段中，与管道壁齐平。设计压力为2.8兆帕（400磅力/平方英寸）。与浆料接触的探头楔块选择在pH值高达14的环境下工作，探头部件在1×10⁶伦琴的辐射剂量下进行了辐射测试。该传感器适用于管道或容器中所有类型液体或浆料的过程控制。
