WebOct 1, 2010 · Flame emissivity is an important parameter for characterizing an open pool fire. Flame emissivity is measured using two methodologies: emissivity inferred from mass burning rate, emissivity measured using infrared thermography. Mass burning rate is measured for gasoline pool fires (0.3 m, 0.5 m, 0.7 m and 1.0 m). WebUsing a Fluke infrared camera, it's important to understand the relevance of emissivity to temperature measurement calculation. All objects radiate infrared energy. The quantity of energy radiated is based on the actual surface temperature and the surface emissivity of the object. The imager senses the infrared energy from the surface of the ...
