> MSU Wind Applications Center
WAC Anemometer Program
Program Overview:
The Wind Applications Center is working to install
several 34 meter (113 feet)
anemometer towers across Montana. To see wind
data from two anemometer towers near Great Falls, MT and Raynesford,
MT, go to the Montana
wind resource page
created by the Plains Organization for Wind Energy Resources (POWER).
To properly analyze a wind resource,
an anemometer needs to be placed at the potential wind site for over a year.
During this time the instruments mounted to the tower will measure the wind
speed, direction and air temperature. All the data from the instruments will be
stored in a data logger or transmitted to the office for further analysis. The instruments on the tower include:
Anemometer (NRG Systems)- Measures
Wind Speed
NRG #40C Anemometers can measure wind speed in the range of 1 m/s to 96
m/s (2.2 mph to 214 mph) (highest recorded). For further information see the
NRG website.
Direction Vane (NRG Systems)-
Measures Wind Direction
NRG #200P Direction Vanes measure wind direction from 0
to 360 degrees. For further information see the
NRG
website.
Temperature Sensor (NRG Systems) -
Measures Ambient Air Temperature
NRG #110S Temperature Sensor has a sensor range of -40
°C to 52.5 °C (-40 °F to 126.5 °F). For further information see the
NRG
website.
Data Logger (NRG Systems) - Records
All Raw Data from Sensors
NRG Symphonie Data Logger is capable of supporting up to
12 different sensors. In addition the logger is campatible with an iPack that
will allow the data to be transmitted wirelessly. For further information see
the NRG
website.
Data Transmitter with PV Panel (NRG
Systems)
Symphonie iPack connects to the Symphonie Data Logger
providing a way to transmit the data using a cellular provider, to an email
address. The iPack is charged by the 5 watt PV panel in the field. For further information
see the
NRG website.
