摘　　要：文中介绍了动态流量计的基本原理、提高稳态精度和动态频宽的设计关键、智能优化设计方案。作者研制的动态流量计是国内流量控制系统中所缺乏和急需的器件，已成功地应用在国产液压电梯流量反馈控制样机上。A new type of dynamic flow sensor is developed. After the description of its basic principle, the critical design methods of increasing the static accuracy and dynamic frequency band width of the sensor are presented. The intelligent optimization design method is also discussed. This type of flow sensor is widely needed in the flow control systems and has been successfully used in the home-produced prototype hydraulic elevator with flow electrical feedback control system.
