  1. Be sure that the fuel rate is corrected for temperature, see table below.

Fuel Temperature
Correction for Flow Rate
Less than 7°C [45°F]
Flow meter is not accurate
7 to 13°C [45 to 55° F]
Subtract 2 percent from flow rate reading
13 to 20°C [55 to 68°F]
Subtract 1 percent from flow rate reading
20 to 29°C [68 to 85°F]
No Correction
29 to 42°C [85 to 108°F]
Add 1 percent to flow rate reading
42 to 56°C [108 to 132°F]
Add 2 percent to flow rate reading
56°C [132°F] above
Flowmeter not accurate

Pressure Conversions
1 in H20 = 0.074 in Hg = 0.036 psi
1 in Hg = 13.600 in H20 = 0.491 psi
1 psi = 2.036 in Hg = 27.680 in H20
