ELLI is an innovative, portable laser measuring device that can be easily monitor difficult or impossible to reach areas and hazardous areas from adistance.
By the TDLAS (Tunable Diode Laser Absorption Spectroscopy) detection technology, it is possible for the user to determine methane safe from a distance. For this purpose, the laser beam must be directed only to the post to be checked. This detection technology therefore provides a high added value for the user who does not have to enter a potential hazardous area for the inspection of pipelines. Only in the event of a gas leak properly trained staff must be employed by an Identified leak check and seal. Previously it was very difficult and especially time-consuming and costly to detect gas leaks using conventional flame ionization or semiconductor gas detectors. By this significantly reduced verification effort the review of gas leading systems or pipelines is very cost effective compared to conventional verification methods.



Typical areas of application:
  • Checking of gas lines, for example Pipeline inspection, checking of lines at great heights
  • Review of hazardous areas, for example Biogas plants, gas pressure regulating stations
  • Recognition of higher methane concentrations in buildings through windows
  • Remote check of enclosed gas plants
  • Unscheduled testing of underground pipelines


Functionality:
For the inspection of gas lines or fittings the laser beam has to be directed to the inspection area. In this case, the device measures the methane concentration using the difference between the emitted and the received (reflected) infrared laser bea. The wavelength of the laser beam used ensures selective measurement of methane.
The measured value is the product of the density of methane between the detector and the targeting point as well as the path length through the cloud of gas. The measured value would be indicated in ppm x m and is a measure of the so-called concentration length.
