摘　　要：介绍了孔板流量计的历史状况及其发展现状,说明自从引入微机技术以后,孔板流量计的测量精度和对环境影响的修正补偿能力均有了大幅度的提高,如测量范围扩大到10:1。还列举了设计示例。Based on introduction of historical situation and development of orifice flowmeter, this paper expatiated that since the introduction of computer technology, the measuring accuracy of orifice flowmeter and its ability on revising and compensating environment effects increased markedly. For instance, the measuring range expanded to 10：1. Designing demonstrations were also given in the paper.

关 键 词：孔板 流量计 测量范围 差压 精度
