摘要
煤气计量的本质是对其干部分进行计量。由于煤气温度变化时,其水蒸气含量会有变化,水蒸气的扣除量相应变化。不仅如此,由于组份变化,混合物的密度也相应变化,所以,只有进行全补偿才能保证测量精确度。
The fundamental of coal gas measurement is to measure its dry part. The steam content in gas will change with the change of gas temperature, thus, the reduction of the steam should be also changed. Moreover, the density of the gas will change due to the change of composition. Therefore, only whole compensation is carried out, can the required measurement precision be obtained.
