摘要
分析了影响流量测量仪表扩展量程比的主要因素,并结合大量程比微机流量计的研制,就扩展量程比的技术方案作了论证,经用文中所介绍的方案扩展后,量程比由3:1提高到了10:1。
The main factors affecting the expanding the range ratio of flow measuring instruments are analyzed. Combining the development of microprocessorbased flowmeter with wide range ratio, the technical scheme of expanding the range ratio is expounded, By using the method stated in this paper, the range ratio has been expanded from 3: 1 to 10: 1
