摘　　要：靶式流量计是常用的流量测量仪表。为便于制造商和用户之间的交流,促进其更快、更有序的发展,具体介绍了靶式流量计的测量原理,提出分类依据和分类命名。根据结构不同,此类流量计分为轴封膜片式、挠性管式、扭力管式和差压式;根据力转换方式不同,分为力-气压转换型、力-电压转换型和力-差压转换型。详细描述了各种类型的结构,提出差压靶的新理论,分析了传统干校法的不足,设计了一种新干校法装置,并呼吁尽快制定靶式流量计的国家标准。Target flowmeter is one of the commonly used instruments for measuring flow. For providing convenient communications between manufacturers and customers, and fast and orderly accelerating the development of target flowmeter, the measuring principle of target flowmeter is introduced concretely. The basis of sorting and naming of the sorts are put forward. According to the different structure, target flowmeter can be divided into shaft seal diaphragm type, flexibility type, torque tube type and differential pressure type. According to different force conversion, the flowmeter can be divided into force to pneumatic pressure conversion type, force to voltage conversion type and force to differential pressure conversion type. The structures of various types are described and the new theory of differential pressure target is proposed. The inadequacy of the traditional dry calibration method is analyzed and a new dry calibration device is designed. The author appeals to work out national standard of target flowmeter in China as early as possible.
