Compared with other available instruments the velometer has the advantages of highly automatic operation, rapid response, flexibility and relatively much lower cost. 2 Sequential flow is the most important function of a step gating system. Till now the studies about it have given little information.

针对以往关于阶梯浇注系统研究中，对各层内浇口分层注入功能研究不够，缺乏定量测量结果的不足，本文工作中采用微计算机化的光电非浸入式流速测量仪，首次实现了对几种典型的阶梯式浇注系统各层内浇口流速在浇注过程中变化情况的动态测量。

Because of the indispensability of such dynamic measurement in simulating investigations of step gating systems, first of all, the paper describes an innovation-a computerized photoelectric non-invading velometer.
