Comparison of ultrasonic type wind speed and direction meter and mechanical type wind speed meter

Wind power generation, the need to obtain real-time data on wind speed, this time will choose to install an anemometer, there are two main anemometers on the market: mechanical anemometer and ultrasonic wind speed anemometer.

Mechanical anemometer uses the rotation of mechanical parts to sense the size of the wind speed, although simple, but also caused a large error, because the mechanical moving parts are easy to wear, life is limited, although the price is low, but the need for follow-up maintenance, maintenance costs are relatively high.

The ultrasonic wind speed and direction meter mainly uses the propagation time difference method, simple and theoretical basis, there are four ultrasonic probes on the equipment, each probe can both send and receive ultrasonic waves, can measure the relative direction of wind speed and wind direction.

Windway technology ultrasonic wind speed and direction meter outdoor weather parameters 24 hours continuous online monitoring, through the digital communication interface will be two parameters at once output to the user.　　It can be widely used in urban environment monitoring, wind power generation, meteorological monitoring, bridges and tunnels, marine vessels, airports and other fields, without on-site maintenance and calibration.

Technical parameters
