摘　　要：论述了双旋涡发生体涡街流量计用于蒸汽流量测量遇到的难题及采用的对策。从理论和实践的结合上介绍了采用温度、压力自动补偿方法进行蒸汽流量测量的基本思想。结合实际，对温度变化引起仪表常数变化所造成的测量误差进行了分析，指出了修正方法，并就有关蒸汽测量中的一些具体问题提出了讨论。To make an approach to the difficult problems occurring in measuring the steam by use of the vortex street flowmeter with double vortex generators and the countermeasures taken. In combination of theory and practice, the basic concept on using the temperature and pressure auto compensation for the measurement of steam flowrate is introduced. In practical applications, the instrument factor modification formula is presented and proven. In addition, some concrete problems on the steam measurement are discussed.
