What You Should Know About a Hot Wire Anemometer

By Ryan Hale


Who would have thought that you could use a hot wire anemometer? You may not be a weather expert but there are many reasons why an anemometer might be a good device to keep around. Here's what you need to know about anemometer types with hot wires.

Hot Wire Types

You probably already learned in elementary school what anemometer is for. It is a useful device when it comes to weather monitoring. In general, all anemometers measure the speed of the wind. You can get information related to either velocity of pressure. There are of course, some units that can give you information on both aspects. Others have the added feature of providing temperature details.

Anemometers aren't all the same. Among the many different kinds is the hot wire type of anemometer. It's pretty obvious from its name that it is a type that carries a hot wire. It is this wire that cools down when the wind hits it. The corresponding difference in electrical resistance is what you need to note to find wind velocity.

The downside to this anemometer is that it can easily be damaged if you aren't particular about its care. It is however an extremely sensitive device and can give prompt, accurate and detailed wind velocity information when you need it the most.

Davis Units

A hot wire unit can be a good piece to keep around. You do have a couple of other options though. If you want other anemometer choices you can head to the Davis website. This is where you will find the right Davis wind anemometer for your specific needs. Davis is a reputable name in the weather monitoring industry so you can never go wrong with this option.

- 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.

- If you are looking for something handy, then the hand held Davis anemometer is just the device for you. It has a precision meter that can give you the speed of the wind in three measurement scales. Its sturdy black plastic case ensures the safety of internal components. You also will not require batteries for this unit.

- There's something even better than a hand held unit from Davis. That's the ultrasonic anemometer. It has more than just a fancy name to boast about. You can bring this handy device where you want to go so you can monitor wind speed, temperature and chill.

Whether it's for ventilation system maintenance, weather monitoring or temperature monitoring for outdoor activities, a good anemometer is the best device to rely on. You can get a hot wire anemometer or choose among the different selections from Davis.
