About - Ultrasonic Anemometer

Ultrasonic wind speed and direction sensors are currently widely used in power safety monitoring, bridges and tunnels, marine ships, urban environmental monitoring, road safety, and other fields.

Ultrasonic anemometer


RS-CFSFX-*-3 ultrasonic anemometer is a measuring instrument that uses ultrasonic waves to propagate in the air to measure wind speed and direction. Its internal use low-power chips, power consumption is only 0.12W. It is especially suitable for solar or battery-powered environments with relatively high power consumption. Thanks to new technology and new technology, the structure is more compact and compact. Optional temperature and air pressure modules are also provided. The shell is made of high-strength ABS material, which is convenient for users to use in different environments. We provide a free cloud platform for customers to view data.

Advantages - Ultrasonic Anemometer

High quality

The shell of this small ultrasonic anemometer is made of high-quality ABS material, which can effectively resist rain, snow, and ultraviolet rays. The four ultrasonic terminals adopt an upside-down design to avoid measurement errors caused by rain, snow, or sand accumulation.

Quick install

This ultrasonic wind sensor can be equipped with a built-in electronic compass and a device with a built-in electronic compass. There is no longer a position requirement during installation, just ensure that it is installed horizontally. Therefore, it can be used in mobile occasions such as marine ships, automobile transportation, etc., and there is no direct requirement during installation.

Long using life

The ultrasonic anemometer has a compact design, the entire structure does not have any parts that need to be moved, and there is no mechanical wear during use, so it has a long service life. Once installed, there is no need for maintenance and on-site calibration during use, which saves worry and effort.

Wide range

The wind speed and direction of this device are measured by the ultrasonic principle, so there is no angle limit, 360° Omni-directional, and accurate wind speed and wind direction data can be obtained at the same time.

Low price

Renke is a professional weather equipment manufacturer with 15 years of production experience and a large and complete production line. Factory-direct sales, in stock. The price of the same type of small ultrasonic anemometer on the market is generally about $130, while the price of the Renke ultrasonic anemometer is only $73.4, which can save you at least 43% of the cost.

More information about ultrasonic anemometers

Q: What is ultrasound?

Ultrasound is a sound wave with a frequency higher than 20000 Hz. It is named after its lower frequency limit is greater than the upper limit of human hearing. It has good directivity, strong reflection ability, and is easy to obtain concentrated sound energy.

Q: Why use an ultrasonic anemometer to measure wind speed and direction?

Compared with the mechanical wind speed and direction sensor, the ultrasonic anemometer has higher measurement accuracy and more stable performance. The structure of the measurement terminal is relatively simple. In many applications, it replaces traditional mechanical wind speed and direction sensors.

Q: How does the ultrasonic anemometer work?

The working principle of the ultrasonic anemometer is that the propagation time of sound waves in the air will be affected by the wind speed component parallel to the propagation direction. The basic components of the ultrasonic wind sensor are composed of ultrasonic transmitters and receivers located at opposite ends of the sampling space.

Q: How to calibrate the ultrasonic anemometer?

Our ultrasonic anemometers have been calibrated before leaving the factory, and they can be used directly without the customer’s secondary calibration.
