In this video I have explained on LEL and UEL concepts practically. Detector used to sense LEL/ UEL. Also is it possible to detect upper level UEL values in multi gas detectors?
Hi , Thank you so much for the explanation about LEL and UEL. Kindly upload the video about Task risk assessment and Risk assessment matrix ? How we can select the severity and probability based on matrix ?
The LEL % seen in the detector display doesn't show that the concentration of a flammabel gas is 5%. If it was so, you would explode when you see the LEL as 5%. That value is the percentage of LEL. Example; you see 10 as %LEL in the screen. It means 10% of 5% (LEL of CH4) which is equal to 0.5% CH4 concentration. Let's give tjhe right information friends.
we call it tankscope brother used to measure inerted tanks which like you said a special measuring device use to read in oxygen deficient atmosphere/tanks.
