建立了滴流床反应器内液体分布的测量系统。该系统可以用29个面积为10 × 10 mm（2）的测量单元的直线阵列准同时测量液体流量的径向分布，或者用单个单元动态测量液体流量。根据电导率法测定每个池中的液体流速。精心设计的校准系统保证测量的标准偏差低于2%。
A measurement system was developed to study the small scale liquid distribution in a trickle bed reactor. The system can measure the radial profile of liquid flow rate quasi-simultaneously with a rectilinear array of 29 measuring cells with 10x10 mm(2) area, or the liquid flow rate with a single cell dynamically. The liquid flow rate in each cell was determined according to an electric conductivity method. A carefully devised system of calibration guarantees the standard deviation of measurement below 2%.
