Meteorological Sensors (Assembly)
Reliable information of
wind movements is a critical requirement for air quality management.
Polluting gases and particulates released from elevated industrial
stacks disperse by a variety of mechanisms and by the time the
pollutants reach ground level their concentration is reduced to a
fraction of the emitted level. The extent of dispersion and the
resultant ground level concentration (GLC) depends upon local
meteorological parameters like wind speed, wind direction, atmospheric
turbulence or stability and the mixing height. Reliable local wind data
can also help to identify possible sources that could be adversely
affecting air quality in an area.
Envirotech
Wind Monitoring Systems have been used for past several years all over
the country by consultants, industry and researchers to generate
micro-meteorological data. Feedback from this large body of users has
often led to system upgrades. The WM271 is our latest model Wind
Monitor with important new features specifically incorporated for
Indian field use.
