Alromar Group gives special attention to the supplying of anemometers, wind vanes and measurement towers from a variety of manufactures, so we can supply you with equipment from leading manufacturers in the market.
An anemometer is a device for measuring wind speed. They are used in measurement towers, installed in all wind power installations and it’s also used in nautical, aeronautical, etc.
The cup anemometer is best known and widespread; it consists of three hemispherical cups mounted at equal angles to each other on a vertical shaft, generating a signal. Currently it’s often used for wind resource assessment studies.
For more reliability registering data, pulse anemometers are preferred. However high frequency pulse anemometers are better. The analogue instruments, besides being more expensive, the signal is more exposed to degeneration and interference during transmission.
Sonic anemometers measure wind speed based on the time of flight of sonic pulses between pairs of transducers. They have a high consumption and therefore require network connection. They are pretty expensive and not recognized by MEASNET.
Another must for any wind measurement campaign is the wind vane; it’s an instrument for showing the direction of the winds. It’s also used in nautical, aeronautical, etc.
There are digital wind vanes or Potentiometer wind vanes (incorporates a precision wire-wound potentiometer as a shaft angle transducer), enabling wind direction sensed by the wind vane to be accurately determined when connected to suitable measuring equipment, such as a data logger or PLC.
The majority of wind vanes are equipped with electronically regulated heating.
Potentiometer wind vanes are the most commonly used in wind measurement towers, because of its simplicity and having very low energy consumption.
It depends on what you are going to use it for; it’s not the same Testing of Power Curve of Wind Turbines than registering data from a prospective tower.
The important thing is that they are always calibrated, and within the range that exists in the market have in mind the following:
The most important preventive measure is the regular inspection of the mast and the reasonableness of the measured data.
