Following World Meteorological Organization (WMO) guidelines, a general recommendation
is that ther
e is at least 150 m open area in all directions from the mast. Any object of height
(h) does not significantly disturb wind measurement at a minimum distance of 10 times the
height of the object.
The recommended minimum length (h) for the mast that is installed on top of a building is
1.5 times the height of the building (H). When the diagonal (W) is less than the height (h),
the minimum length of the mast is 1.5 W. However, follow the application specific
instructions and local regulations when placing WXT530.
