Characteristic design parameters for fluid dynamics and mass transfer of packed column internals are usually obtained from laboratory or pilot plant experiments. At this scale, results are often affected by liquid maldistribution. Knowledge of liquid distribution is necessary to quantify the influence of maldistribution on mass transfer efficiency and helps to prevent an overdesign of industrial packed columns. The applicability of a minimally invasive wire-mesh sensor for distribution measurements is investigated and a measuring and evaluation method is developed and applied to investigate liquid distribution for the Pall Ring 25, the Raschig Super Ring 0.6 and the Montz Pak B1.250. The results for both, tracer, and integral liquid distribution, show a high reproducibility and are in good agreement with published liquid distribution behavior. The wire-mesh sensor can provide valuable results as a supplement or alternative to liquid collectors with little additional experimental effort in fluid dynamics and mass transfer measurements.

填充柱内部的流体动力学和传质的特征设计参数通常从实验室或中试工厂实验中获得。在这种规模下，结果通常会受到液体分布不均的影响。了解液体分布对于量化分布不均对传质效率的影响是必要的，并有助于防止工业填料塔的过度设计。研究了一种微创金属丝网传感器在分布测量中的适用性，并开发了一种测量和评估方法，并将其用于研究颇尔环25，拉西格超级环0.6和Montz Pak B1.250的液体分布。示踪剂和整体液体分配的结果均显示出较高的重现性，并且与已公布的液体分配行为良好吻合。
