A few centuries ago used to determine wind strength and direction. They had a wide range of applications and were especially often installed in coastal cities and areas related to navigation. Now such a device performs an exclusively decorative function and is considered an original exquisite decoration for the house.
The principle of the device is very simple: a metal plate called the fly-gun, rotates under the influence of an air stream, specifying thus its directions. At the same time, the wind speed can be determined by the rotation speed. Despite the simplicity of the principle of operation, the price of a weather vane is not always low: it is often an exclusive forged product.
The design of the wind vane consists of three elements :
A metal rod that is attached to the roof and holds onto all the fixture .
Plate-flyugar , necessary in order to catch the flow of wind and rotate under its action. As it uses a flat figure.
Wind rose with the designation of the cardinal points indicating the direction of the wind. It must be firmly fastened so as not to twist.
According to their purpose, the devices are divided into the following categories:
Meteorological are very thorough balancing and distribution of forces. In professional terminology, they are called anemorumbometers. Installed only on weather stations.
Wind or wind vane Wilde are needed to measure wind strength. They are usually complemented by a vertical plate, swinging in different directions. This element by its deviation from zero and shows the power of the flow. Also for these purposes a small propeller can be used, the advantage of which lies in the fact that it frightens away birds.
Chimney weather vanes are needed so that the wind does not blow into the chimney, and all the combustion products freely go outside.
Decorative devices are not very accurate readings and are used only for the decoration of buildings. The direction of the wind indicates approximately the figure with the image, for example, of an animal or a ship. If you are not interested in accurate information about the parameters of the movement of air masses, then you can buy a weather vane of this type.

In the Middle Ages, it was believed that the figures installed on the roof had mystic power and were able to protect the owners from danger and misfortune. For this reason, the attitude towards them has always been very reverent and attentive, and still a classification of devices has been formed, depending on what they symbolize. Now the figures, as a rule, are intended to somehow characterize the tenants. The most commonly used images are birds, fairytale characters, monograms, flags, angels, zodiac signs and other elements of symbolism and mysticism.
One of the most common images on weathervanes is a rooster figurine. The fact is that according to ancient beliefs such a bird drove away all evil from the dwelling. It was installed in order to protect themselves from thieves, fires or invasions of enemies. Another common version of the figure is the stork. It was believed that he will bring home strength and new life. Such a weather vane received almost universal distribution in Scandinavia.

Any domestic animals, for example, cows or horses meant friendship.

This will protect it not only from precipitation, but also from ultraviolet radiation, and also give the product a pleasant shine.
If the figure has simple outlines, then it is cut with scissors made of copper sheet or another metal. A more interesting and complex flygun can be cut with an electric jigsaw. However, this procedure is laborious and requires special skills. There is a more expensive, but at the same time more efficient way - laser cutting. It allows you to make shapes of absolutely any degree of complexity.
Pay attention to the fact that if you pursue individuality, then you should not buy copper vane on the roof, made by stamping. Minted and forged fly-flakes are always more exclusive.

is installed on the roof The weather vane will serve you well and cope with its functions only if installed correctly and reliably. In order for it to be performed well, it is better to turn to professionals. In general, the entire installation procedure is not complicated, however there are some rules.
The weather vane must be fastened at the highest point of the roof. It may be a fad or end of the chimney. To maximize the accuracy of the readings, the device must be installed at a height of at least 10-12 meters. This will allow the wind to freely blow the entire device. For the correct location of the wind rose is to use a compass.
Flygark should be attached to a steel tube with a freely rotating rod. For the system to work properly, it should be given a strictly vertical position relative to the horizon. To do this, use a variety of devices, such as level or plumb. Fastening reliability is enhanced by using metal plates mounted on the sides.
Free rotation of the device on the base is provided by mounting the bearing. In this case, in no case should moisture get into the rotation node itself. Therefore, you can attach a special umbrella just above the rod. Modern weathervanes are equipped with metal-graphite bearings, less susceptible to corrosion. In addition, such a device provides more accurate readings, as it is much more sensitive.
Also, a roof vane mounted on the roof can function as a lightning conductor. To do this, it is only necessary to ground it properly. This should be done in accordance with special instructions and manuals. But in our time, the direct functions of such devices have faded into the background. Now the weather vane is needed in order to give the building a more decorative look and emphasize the wealth and good taste of the owners.
