What is LEL? Crowcon Detection Instruments Ltd

The Lower Explosive Limit (LEL) is the lowest concentration of a gas or vapour that will burn in air. The Lower Explosive Limit (LEL) varies from gas to gas, but for most flammable gases it is less than 5% by volume. This means that it takes a relatively low concentration of gas or vapour to produce a …

Why LEL important in Gas Detection? Inst Tools

Typical safety standards require that a gas detection unit give warnings at 10 – 20% of the LEL. Do not confuse the alarm level with the volume of gas required to reach the LEL. For example: Methane has an LEL of 5% by volume in air. For a gas detector to give an alarm at 10% of the LEL…

Definition of LEL Lower Explosive Limit

In gas detection systems the amount of gas present is specified as a percentage (%) of LEL. Zero percent Lower Explosive Limit (0% LEL) denotes a combustible gasfree atmosphere. One hundred percent lower explosive limit (100% LEL) denotes an atmosphere in which gas …

CORRECTION FACTORS FOR COMBUSTIBLE GAS (LEL) …

“corrected” span gas concentration when prompted for this value. For example, to read in isopropanol LEL units, apply 20% LEL Methane but enter 20 x = 52 for the span gas concentration. Oxygen Requirement and Matrix Effects LEL sensors require oxygen for combustion and cannot be used in environments that contain less than 10 vol% oxygen.
