  • 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.

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of
