How to Detect so2 Liquefaction System for gis

Atmospheric SO2 is an important indicator for volcanic eruptions and volcanic activity like passive degassing. Space based atmospheric sensors such as GOME-2 on MetOp and OMI on EOS-Aura make it possible to detect the emissions of volcanic SO2 in near-real time (NRT) and monitor volcanic activity and eruptions on a global scale.

  • [An ultraviolet spectroscopy method for rapid partial

    By selecting the appropriate wavelength range (295~305 nm), ultraviolet spectrum can identify SO2 from the complex by-products of SF6. In this paper, firstly, the author reviewed the decomposition mechanism of SF6 under partial discharge, and then verified the rationality of detecting partial discharge by UV, and ultimately achieved the rapid detection of GIS partial discharge and fuzzy judgment of discharge time.

  • How does GIS for Water Leak Detection Work? - The Water

    Water loss is something that can be prevented if the leakage is detected in time and if it is rapidly fixed. The problem with detection is that only bigger leaks get detected, often even they get noticed and reported after the pipe bursts. Satellites can detect leaks as small as 0.5 l/min. As well as being the most precise, they are the fastest.
