摘　　要：介绍采用相关法试制的带微处理机控制的电容式颗粒速度测量装置.该装置不仅能连续监测气固两相流中的颗粒流动瞬时特征,而且能对数据进行分析,瞬时值及统计平均值用数显方式显示,系统还具有过程报警、调节、外接打印等多功能.The capacitance measuring device for velocity of granular media which is adopting correlation and based on microcomputer control is introduced. The device not only monitors the instantaneous characteristics of the granular media in dual phase flow but also analyses the data and displays the instantaneous values, statistic average values in digits. The system also features process alarm, regulation and external printout.
