t2 = Ambient temperature (°C)
p1 = Reference air pressure (hPa)
t1 = Reference temperature (°C)
T = t + 273 °C
1 1
T = t + 273 °C
2 2
Example:
Displayed value 10 L/min, temperature 24 °C, air
pressure 960 hPa
10 L/min (20 °C/1013 hPa) x (24 °C + 273 °C) x
1013 hPa
2 =
960 hPa x (20 °C + 273 °C)
2 = 10.7 L/min (at 960 hPa and 24 °C)
