Ultrasonic wind sensor

A strong resonating sound wave in a small space gives a signal to noise ratio more than 40db stronger than other ultrasonic technologies. The FTSeries of ultrasonic wind sensors deliver highly accurate and consistent wind speed and direction data from compact sensors. With no moving parts, built- in heaters, and resistance to a wide range of environmental factors, the FTseries sensors are maintenance-free and will last for years, even in the harshest of . Robust and reliable ultrasonic anemometer for wind measurement for meteorology, aviation, maritime and wind energy applications.

The WMT7uses ultrasound to determine horizontal wind speed and direction. The measurement is based on transit time, the time it takes for the ultrasound to travel from one transducer to .

The latest of which is an ultrasonic wind sensor that uses the time of flight of ultrasonic pulses to . This is the first of a series of posts to follow. I will describe my attempts to build an ultrasonic wind meter ( anemometer ) based on an Arduino Uno. By the time of writing, I have a working prototype but it will take me a while to catch up in this blog. So this is just the first post – more will follow soon.

A Lufft Ventus ultrasonic wind speed and direction sensor , an example of devices that may replace cup anemometers, work well even in freezing weather. Whether mechanical, ultrasonic or laser wind measurements: All measuring methods have technical limits. While for mechanical wind sensors the measuring element – cups and vanes – itself predominantly produces a disturbance in the flow fiel for ultrasonic anemometers a disturbance can be caused . The accurate wind sensor uses the run-time differential method for determining the wind speed and wind direction.

Data output through serial or . Extremely precise and maintenance-free measurement of wind velocity and wind direction as well as calculation of acoustic virtual temperature. The ultrasonic wind sensor is designed without mechanical parts as they have been used with traditional cups and vanes. The digital or analog output delivers instantaneous,. The sensor features durable corrosion-resistant construction with opposing pairs of ultrasonic transducers supported by . The sensor offers high performance and low power consumption in a compact size.

CV7-C is the high speed ultrasonic wind sensor. It is ideal for the most demanding wind sensing applications. The long carbon arm allows the CV7-C sensor to measure the wind further from the disturbance caused by the rigging and sails.

Lightweight: less than 1gr (arm included). The CV7-C has a data rate which is twice as fast as the CVand CV7-V. Video describing the Gill WindSonic. Development of an Ultrasonic Anemometer. At this moment wind sensors or anemometers can be divided into two types.

Static ones based upon the ultrasonic principle and mechanical cup and vane types sensors. Wind measurement with ultrasonic. Observator offers a wide range of wind sensors with these two principles, which all have one thing in common: designed to be used within the hardest .
