通过理论分析对金属兰在强迫热交换下，建立了测量气体流量数学模型；设计了温度补偿电路，通过实验数据对其性能作出了评价，使恒温热线式气体流量传感器具有灵敏度高、响应速度快、测量范围宽等特点．此测量方法可广泛应用于各种可燃气体流量的测量。
Through the theoretical analysis, a mathematical model of measuring gas flow rate is established for metal Lan in forced heat exchange. A temperature compensation circuit is designed and its performance is evaluated through experimental data. The thermosensitive hot gas flow sensor has high sensitivity and fast response , Wide measuring range and so on. This measurement method can be widely used in a variety of combustible gas flow measurement.
