Ultrasonic wind speed and direction sensor: accurate, maintenance-free wind monitoring

Traditional cup or vane sensors rely on mechanical rotation, which can easily lead to measurement errors or equipment failures due to wind, sand, icing, aging, etc. In high-risk scenarios such as wind power, incorrect wind speed data can mean hundreds of thousands of yuan in operation and maintenance losses.

In contrast, ultrasonic wind speed and direction sensor helps users obtain more accurate, continuous, and low-maintenance wind speed and direction data with its advantages of non-contact, fast response, and long life.

Core advantages of ultrasonic wind speed and direction sensor

The ultrasonic wind speed and direction sensors we provide are designed and performed for the professional market, and are suitable for complex environments such as sudden changes in wind speed, high corrosion, and high humidity.

Stronger measurement performance, stable adaptation to extreme climates

The wind speed measurement range is up to 0~75m/s, leading the industry average

The wind direction measurement range is 0~360°, with an accuracy of ±3°

Fast response speed, can capture sudden changes in wind in real time

Sturdy structure, maintenance-free

No moving parts, resistant to wind and sand, rain and snow

Some models have automatic heating system to prevent icing

Optional IP66~IP68 protection, suitable for various environments such as seaside, plateau, forest, etc.

Real use case: The monitoring reliability of wind farms has been significantly improved

Take a coastal wind power project as an example. The original mechanical anemometer caused the wind turbine to stop by mistake due to winter icing, and the average annual operation and maintenance downtime loss reached 350,000 yuan. After replacing it with our ultrasonic wind speed and direction sensor, not only the wind speed monitoring stability is improved by 92%, but the ultrasonic wind speed and wind direction meter is maintenance-free, which greatly reduces the labor and spare parts costs.

Comparison between ultrasonic wind speed and direction sensor and traditional anemometer

Indicators	Ultrasonic wind speed and direction sensor	Traditional mechanical anemometer
Measurement method	Sound wave propagation time difference	Wind cup/wind vane rotation
Accuracy and response	High accuracy, real-time response	High latency, easy to drift
Service life	5~10 years, no maintenance required	Severe wear and tear, need to be replaced regularly
Weather resistance	Corrosion resistance, antifreeze, wind and sand resistance	Easily affected by rain, snow and dust
Cost efficiency	Slightly higher in the initial stage, long-term cost saving	Initial cheap, frequent maintenance

Selection suggestions for ultrasonic wind speed and direction sensor

Depending on the application scenario, users should pay attention to the following aspects when purchasing:

1. Communication interface and system compatibility

Supports mainstream protocols such as RS485, Modbus, 4~20mA, NMEA, etc., which is convenient for access to data collectors and cloud platforms.

2. Does it support solar power supply?

For outdoor installation or powerless environment, it is recommended to choose a model that supports solar power + lithium battery integrated power supply.

3. Installation method and height

It is recommended to install it in an unobstructed location away from large buildings; it is recommended to install it on the top of the wind turbine tower or on an independent bracket upwind of the wind farm.
