| 摘 要： | 通过与煤矿管道瓦斯抽放中采用的孔板流量计相比较,涡街流量计是煤矿瓦斯抽放管道流量测量的理想仪表。为了解决在小流量测量和管道周围存在周期振动的场合下涡街流量计显示出的不足,提出了一种新的信号处理法。通过大量试验证明,设计出了适合在煤矿瓦斯抽放管路中使用的新型涡街流量计。

| Abstract: | In comparison with the pore plate flowmeter applied in the mine gas drainage pipeline,the vortex gas flowmeter would be the rational instrument to measure the gas flow in the mine gas drainage pipeline.In order to solve the small flow measurement and the display shortage of the vortex flowmeter under conditions of the periodical vibration filed existed in the pipeline surroundings,a new signal processing method was provided.With great tests certified,a new vortex flowmeter suitable for the mine gas drainage... |
