Applications & Industries

Scarlet wireless anemometers have been applied to varieties of industries for wind speed & direction monitoring. The risks associated with wind are often underestimated by the public. The Scarlet wind monitoring systems ensure workforce safety and regulatory compliance on cranes as well as other industries.


Fast and easily improve your everyday planning and decision making for your farm. You can employ it to measure wind speeds, determine growing locations and areas to erect wind generators. Also use anemometers to collect long term environmental data about an area. Apply our high level technologies to operate efficiently, save on input costs, and improve crop performance and productivity.


All construction project and especially high angle construction projects operates under wind risk. Monitoring wind speed and wind direction is a vital issue when it comes to safe operation of construction sites. It is a primary consideration to ensure worksite safety. Severe weather conditions can affect site safety straightforward with wind gusts and high wind speeds posing a deathful threat, especially for construction projects with open envelopes allowing wind to pass through construction projects.


Marine ports and terminals liability insurance covers a range of possibilities, including business interruption and losses or damage due to weather conditions. Wind speed direction can significantly affect the position of a ship or oil platform. Regulations require that the vessels record weather data, including wind speed on a regular basis, with data displayed continuously on the bridge. Scarlet offers a complete solutions when it comes to monitoring and recording wind speeds at ports ,harbors and all offshore applications like live wind gust.

Outdoor Events

When people come to play or perform in the great outdoors, the weather conditions often matters to our safety. Accurate wind data is required for both the build and setup process as well as during outdoor events. Monitoring of actual rigging loads, weight distribution and wind speed allows operators to make informed decisions regarding the stability of a structure.

Office Tower

Building skyscrapers is a common engineering project nowadays. Changeable climates also matters to workers at the construction site. Strong wind up there while under construction is a big threat for workers and might be fatal. Accurate wind speed and direction are essential in this kind of situation to prevent fall-related tragedy.


The rapid increase of offshore wind farm projects has given rise to the need for accurate, easy to use equipment to measure the wind on locations several kilometers from the coast. If installed offshore, the traditional mast equipped with anemometers requires a
large and heavy platform to sustain the weight and the size of the structure. Scarlet wireless anemometer is the best solution. It not only measures accurately but also reduce the burden by minimizing the size of the structure.

Wind speed accuracy is +/- 2%FS. We guarantee every wind speed sensors is calibrated and tested before shipment.

The wireless module used on wind speed sensors only requires very low power consumption. The transmission power consumes 20-30 uA in normal condition and 35 mA peak current in every 2 seconds. The standard 3.6V Lithium battery can sustain the sensor for up to 3 years.

The transmission distance can reach as far as 500 meter in open space. The actual distance depends on the topology & obstacles. According to user experiences, the vertical transmission distance can be 200 meters in height. Harmonic disturbances are possible in theory, but so far we did not receive complaints about this.

Pairing between sensor & receiver is based on address. 

The address is labeled on the sensor body. User can set receiver address by setting menus. All WR-3 PLUS were paired and tested before shipping. If the text instruction is still not clear, please visit this video.

Yes. Users can connect unlimited receivers to one wireless sensor.

Yes. We have Bluetooth wireless anemometer for smartphone (Android and iPhone) users. For more information, please visit our Smart Windy product page.

Manufacturer and third party (issued by SGS) Lab certificates can be ordered on demand.
