摘　　要：目前在非贸易计量的燃气调压站箱中所使用的流量计成本较高,因此本文提出一种在非精确贸易计量时,采用较廉价的压差传感器取代价格昂贵的涡轮流量计的方法。本文应用MATLAB中系统辨识工具箱对间接流量监测进行建模仿真,通过对不同站箱的数据监测,得出结果:该模型可以在保证一定精度的情况下代替流量计进行流量计量。At present,the cost of the flowmeter used in non-trade measurement gas station or tanks is relatively high,so this paper proposes a method of using a cheaper differential pressure sensor to replace the expensive turbine flowmeter in non-precision trade measurement.In this paper,the system identification toolbox in MATLAB is used to make up modeling experiments on the indirect flow monitoring system,and the data is monitored through different station or tanks.The results show that the model can replace the flow meter with a certain accuracy.
