What can be done to keep wind from affecting leak detection?

Leak detection of gaseous materials requires a wind to allow the leak to be traced back to the source. The only thing that can be done about the wind is to choose a day for the leak detection which is calm enough to allow a reasonable "trail" to nee established. Zero wind will allow the contaminant to build up in an area with less indication of where it is coming from, too turbulent a wind will disperse the material and make following the leak to its source more difficult.For leak detection near specific sources (valves, flanges, vents, etc) the wind plays a reduced importance as the sensor is places very close to the suspected source and the dilution by the wind is minimal.
