What You Should Know About a Hot Wire Anemometer
Anemometers with Hot WireIf you have a fascination for the weather, you would need a good anemometer. This is a device that can give you information on how fast the wind is blowing. Depending on your point of concentration, you can get an instrument that measures only the velocity of the wind or only the pressure of the wind. Many instruments will give you information on both.
There are many different types of anemometers. One popular type is the hot wire. As its name suggests, it has a hot wire. When air passes through the wire, it undergoes a cooling effect which in turn has an impact on electrical resistance. The change in resistance will determine the velocity of the wind.
Some hot wire models can break easily if you don"t follow instructions for proper maintenance. They remain a popular choice though because this type can give highly accurate wind information even in low wind conditions.
Davis Units
As mentioned, hot wire versions aren"t the only ones you should consider. If you are looking for other great anemometer options, you should try looking for one made by Davis. There are many reasons why you should prefer a Davis wind anemometer. The top reason however is that it is a leading name in weather monitoring devices.
- If you are a first timer or amateur at weather monitoring, you can try the standard device from Davis. The long cable of this unit can be attached in high positions which are what you need for measuring wind velocity. With this device, you can get information on both direction and speed.
- On second thought, you may not want to have to climb a post to attach an anemometer. If you want wind information nearer to your level, then you should get a hand held device. The Davis model can provide very accurate measurements in a triple scale. The best thing about it is that its parts are so well protected that the device can last for years.
- You"ll get even more for your money with the ultrasonic anemometer. This model is handy and convenient too which makes it perfect for wind speed measurement when you need a quick readout for outdoor activities. Aside from speed, this unit can also measure temperature and wind chill so you"ll know if it"s too cold to go jogging in your shorts.
You don"t have to be a wind fanatic to appreciate a hot wire anemometer or a Davis unit. An anemometer is a useful device for any household.
