Features to Look for Before Buying
To give you a clear idea of what device is suited for your application, take a look at the following features.
Digital anemometers come in two types. One with a vane wand that connects to the device through an extensible cable. The other is a single unit handheld device with the vane sitting on top of the digital display.
Anemometers like the Holdpeak and AOPUTTRIVER have detached vane wands that are retractable. With this, you can reach HVAC grilles that are in higher areas without having to use a portable ladder.
While they are both handheld devices, anemometers like the BTMeter BT-866A and Proster require you to use one hand only. These devices can be mounted on a tripod for long-duration wind speed tracking.
Most digital anemometers run on battery power. Some may require you to replace batteries once or thrice in the useable life of the tool.
However, it is best if you look for models that have a power-saving mode like auto shutdown after minutes without operation. It should help you preserve battery power.
No matter the accuracy of an anemometer, it is not convenient to use if it does not display the values in units of measurement that are readable. Look for devices that have display units in meters per second (m/s), kilometers per hour (km/h), feet per minute (ft/m), knots (kt), and miles per hour (mph).
Data Storing and Transfer
Modern anemometers include advanced features and options to save and store data. Look for a device that can connect to a mobile device like a laptop or computer.
The best data transfer option you can find is via a USB. With this feature, you can import and keep track of the HVAC’s performance.
For added convenience and ease of use, make sure the anemometer has a backlight display feature. This feature should be beneficial when it comes to working in darker areas.
For a single unit handheld digital anemometer, make sure it has a mounting option so you can leave it sitting on a tripod to record constant wind speeds.
Conversely, the vane wand should also have a tripod mounting hole for either reaching higher distances or for leaving it to track and record.
With these mounting options, you are ensured to obtain a handheld device that can also act and perform like a fixed device.
Water or moisture resistance is not a feature that all brands or models offer. This quality can only be found in quite expensive anemometers.
Since you are dealing with loads of wind, moisture build-up is not something that you can avoid in the process. Make sure to go for ones that are heavy-duty and meant for professional HVAC diagnostics purposes.
Other modes that you should look for in an anemometer is its ability to measure wind velocity, temperature, and wind flow. Apart from that, it should be able to display the maximum, minimum, average, and current wind speed.
Frequently Asked Questions
How do digital anemometers work?
Digital anemometers have small propellers that spin depending on the speed of the wind that passes through it. These devices count the number of rotations or turn to detect wind speed.
You will get an instant reading of the wind speed on the digital display of a handheld digital anemometer.
What units does the anemometer measure in?
An electronic and battery-operated anemometer measures wind speed in meter per second (m/s), kilometer per hour (km/h), mile per hour (ml/h), feet per second (ft/s or FPS), feet per minute (ft/m or FPM), and knots (kt).
What is the difference between a wind vane and an anemometer?
A wind vane measures the wind. It will face or point towards where the wind is coming from. On the other hand, the anemometer measures wind speed through small propellers.
