* Be sure that the fuel rate is corrected for temperature.
Fuel TemperatureCorrection for Flow Rate
Less than 7°C [45°F]Flow meter not accurate
7 to 13°C [45 to 55°F]Subtract 2% from flow rate reading
13.0 to 20.0°C [55 to 68°F]Subtract 1% from flow rate reading
20.0 to 29°C [68 to 85°F]No Correction
29 to 42°C [85 to 108°F]Add 1% to flow rate reading
42 to 56°C [108 to 132°F]Add 2% to flow rate reading
56°C above [132°F]Flow meter not accurate
Pressure Conversions
1 in. H 2 0 = 0.074 in. Hg = 0.036 psi
1 in. Hg = 13.514 in. H 2 0 = 0.491 psi
1 psi = 2.036 in. Hg = 27.7 in. H 2 0
