LEL Monitoring

FLAMMABLE GAS DETECTION

Why Do I Need Flammable Gas Detection?

Flammable gas monitors should be considered where combustion is possible. when a chemical reaction between oxygen and another subsatance that results in a rapid release of energy mainly as heat. Therefore O2 monitoring should be also be considered. For more information please see OXYSAFE- oxygen  & GAS SAFE - multi gas systems.


Gas detectors should monitor the limits of flammability. The lower explosive limit (LEL) of a gas is the concentration up to a point where insufficent gas is available to produce an explosion. The upper explosive limit (UEL) of a gas concentration is value that a gas is too rich to ignite.


A flammable gas detector should be selected and calibrated to the gas in use such as methane (CH4), Butane (C4H10), Propane (C3H8), Hydrogen (H2), Ethanol or Heptane (C7H16). Please state this when ordering.
