摘　　要：介绍了新型质量流量计的结构、测量原理,采用FLUENT软件对该质量流量计进行仿真模拟。模拟分析了适用于该质量流量计的流体流速范围、环境温度范围。适用于该质量流量计的流体流速范围为0.2～1.6m/s。当流体流速为1m/s、温度为60℃时,适用于该质量流量计的环境温度范围为-20～120℃。当环境与流体温差小于20℃时,不建议采用该质量流量计。The structure and measurement principle of a new type mass flowmeter are introduced. This mass flowmeter is simulated by Fluent software. The range of flow rate and the range of ambient tem- perature suitable for this mass flowmeter are analyzed. The flow rate suitable for this mass flowmeter is 0.2 to 1.6 m/s. When the flow rate is 1 m/s, and the temperature is 60 ℃, the temperature range suitable for this mass flowmeter is -20 to 120 ℃. When the difference between ambient temperature and fluid temperature is less than 20 ℃, it is not suggested to use this mass flowmeter.
