3.5.4 Conversion Factor for Imperial Gas Flow Meters
Required Data: Pressure of gas at meter in “wg
Required gas flow in ft³/min
Calculations: Correction factor = (pressure of gas at meter x 0.00228 ) + 0.948
Reading on gas meter = required gas flow / correction factor
Example: Pressure of gas at meter = 58” wg
Required gas flow = 95 ft³/min
Conversion factor = (58 x 0.00228) + 0.948 = 1.08
Reading on Meter = 95 / 1.08 = 88 ft³/min
3.5.5 Correction Factor for Burners Significantly Above Sea Level
Note: Above sea level i.e. >200m (1ft = 0.3048m)
Height above sea level in meters, Calculation for correction factor: =
(Pressure of gas at meter x 0.00228) + (0.948 – (height above sea level x 0.0001075))
Example: As above but 250 m above sea level:
Correction factor = (58x0.00228) + (0.948 – (250 x 0.0001075)) = 1.05
