3.5.2 Conversion Factor for Imperial Gas Flow Meters
英制燃气流量表的换算因子
Required Data: Pressure of gas at meter in “wg
Required gas flow in ft³/min
所需数据:
在流量计处的燃气压力,单位
“wg
所需燃气流量,单位:立方英尺
/
分钟
Calculations: Correction factor = (pressure of gas at meter x 0.00228 ) + 0.948
计算:
校正系数
= (
在流量计处的燃气压力
x 0.00228) + 0.948
Reading on gas meter = required gas flow / correction factor
燃气表读数
=
所需燃气流量
/
校正系数
Example: Pressure of gas at meter = 58” wg
例子:
在流量计处的燃气压力
= 58” wg
Required gas flow = 95 ft³/min
所需燃气流量
= 95
立方英尺
/
分钟
Conversion factor = (58 x 0.00228) + 0.948 = 1.08
换算因子
= (58 x 0.00228) + 0.948 = 1.08
Reading on Meter = 95 / 1.08 = 88 ft³/min
燃气表读数
= 95 / 1.08 = 88 ft³/min
3.5.3 Correction Factor for Burners Significantly Above Sea Level
较高海拔处燃烧器运行的校正系数
Note:
Above sea level i.e. >200m (1ft = 0.3048m)

Height above sea level in meters, Calculation for correction factor: =
海拔高度(米),校正系数的计算:
=
