WebMethane Answer / Solution The LEL of a gas is the lowest concentration of that gas which can combust. A reading in %LEL measures the percentage of that LEL value. For example, for methane, the LEL is 5% by volume. 50% LEL is half of that value, or 2.5% by volume. WebMay 1, 2014 · This is particularly important for methane detection when calibrating with a gas other than methane. Periodic exposure of a known concentration of methane gas to …
