摘要
在介绍了孔板流量计的历史状况和新的进展的基础上指出,自从引入微机技术以后,孔板流量计的技术水平得到了提高,表现在大幅度提高了精度和引入完善的修正技术,使该产品的测量范围扩大到10:1.文中还列举了设计示例.
On the basis of the introduction of the historical status and the development of the orifice flowmeter, it is stated that the technical level of the orifice flowmeter has been enhanced since the microprocessor technology involved. The enhancement includes the highly increased accuracy and the comprehensive correction thehnology. Thus the measuring range has been expanded to 10:1. The design examples are also given.
