DEC.LEL™

LEL (Lower Explosive Limit) monitoring and automatic recirculation systems play a critical role in ensuring safety and optimizing operational efficiency. Furthermore these systems are a crucial element to be evaluated when you are planning to install a VOC emission control system (e.g. a solvent recovery unit, or a thermal oxidizer).

Increasing energy costs are requesting our customers (flexible packaging and converting industries, using rotogravures, flexo and lamination machines) to explore and evaluate energy saving technologies, in order to increase their competitiveness in the global market.

DEC.LEL™ • what is a LEL detector?

An LEL detector, or LEL meter, is a process analyzer (DEC.ATX™) that quantifies dangerous levels of combustible gases or solvent vapors in the air, expressed as a percentage of the Lower Explosive Limit (LEL). It serves as an essential element within a complete gas detection system.

DEC.LEL™ • measured values (%)

Explosivity is typically measured in %LEL (0-100% LEL), where 100% means the gas concentration has reached the lower explosive limit and became explosive.

DEC.LEL™ • key terms

  • LEL: Lower Explosive Limit: the concentration of a combustible gas or vapor in air below which an explosion or flame cannot occur due to insufficient fuel.
  • UEL: Upper Explosive Limit: the concentration of a combustible gas or vapor in air above which an explosion or flame cannot occur due to insufficient oxygen.
  • Sensitivity: refers to the degree to which a gas detector senses changes in gas concentration.
  • Detection accuracy: refers to the comprehensive performance including the correctness, accuracy, repeatability of the value displayed by the gas detector (or the value indicated by the measurement result).
  • Response time: When the concentration of the test gas changes instantaneously, the time required for its indicated value to be controlled within a specific range of the final value.
