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

Windows XP compatible, Envirotech MetLog software is provided for data download to a PC and analysis. MetLog supports communication via PSTN, GSM modems and direct cable connection to RS232 / USB ports. Analysis tools include export to MS Excel, Graphs, Monthly Averages & Windrose Diagrams
WM 271 is powered by a rechargeable Ni-MH battery pack that can keep the system operating for about 15 hours. The standard system is supplied with a main powers based charger. An optional Solar Panel based charger can also be provided
WM 271 is especially designed to be used on table tops or mounted on a pole for continuous stand-alone operation. Further, emphasis is given on the control of the instrument through a computer rather than direct interaction of an operator with the instrument
