    • A system and method for using a probe-based guided-wave radar sensor to measure fluid level in a container in a non-contact mode are provided. The system and method of the current invention replaces a wall section of the fluid container, such as a steel slurry tub with a panel of radar-transparent material, such as plastic. The level probe is mounted external to the container, adjacent to the radar-transparent panel. By avoiding contact between the sensor probe and the fluid, whether the fluid be cement slurry or another fluid prone to probe degradation, it is possible to eliminate the possibility of contamination, build-up, caking and/or damage to the probe along with the associated degradation in sensor performance.
    • 提供了一种使用基于探针的导波雷达传感器以非接触模式测量容器中的液位的系统和方法。 本发明的系统和方法用诸如塑料的雷达透明材料面板代替流体容器的壁部分,例如钢浆桶。 水平探头安装在容器的外部,靠近雷达透明面板。 通过避免传感器探针和流体之间的接触,流体是否是水泥浆料或容易发生探针降解的另一种流体,可以消除探头的污染,积聚,结块和/或损坏的可能性以及 相关的传感器性能退化。
