摘　　要：文章采用压电晶体传感器利用卡门涡街原理,设计了一种气体流量测量仪的结构,分别对气体流量测量仪结构的各个部分进行了分析。并对压电晶体产生的电荷信号进行处理,分析和设计各个环节的电路。该流量计所用检测压电元件不接触气体,适于恶劣环境、不易结垢,耐高温、高压、安全防爆,适用于测量封闭管道的气体累计流量和瞬时流量。This passage has designed the constructions-of gas flow measurement instrument. Instrument is developed with the help of piezoelectric crystal unit sensor, based on Carmen vortex street theory. This passage has designed the constructions of gas flow measurement instrument and analyse each parts of the constructions. Charge signals generated by the piezoelectric crystal is disposed and analysed, and the circuit of each parts is also designed, and the piezoelectric crystal can be keep clear of gas and deposited difficultly. The instrument is safe from explosion and fitted to measure gas accumulative flow and instantaneous delivery in closing pipe system.
