  • Brand: METER
  • Model: ATMOS 22
  • Description: Measuring wind has always involved tradeoffs. Cup anemometers can’t measure both wind speed and wind direction (or low wind speeds). And they're prone to malfunction since they contain moving parts. M

ATMOS 22 Ultrasonic Anemometer Description:

Accuracy that will blow you away

If you want accurate wind profiling, a sonic anemometer is the obvious choice. Designed with canopies in mind, the ATMOS 22 sonic anemometer registers even the lowest thresholds of wind speed (0 m/s) with the added ability to detect fine-scale variations within 0.01 m/s resolution.

Contrast the ATMOS 22’s advanced technology to a cup or propeller wind anemometer. Neither will spin if wind speed is too low. Cup anemometers also don’t indicate wind direction, unless you combine them with a wind vane. And both are prone to additional inaccuracies due to worn out moving parts. But with the ATMOS 22, you can accurately measure wind speed anywhere, every time, with total confidence.

A low-cost sonic anemometer. Yes, you heard right.

The ATMOS 22 is not only far more affordable than other sonic anemometers but also uses 100 to 1,000 times less power. Running on less than 100 uA, the ATMOS 22 frees you to make wind measurements in multiple locations without having to constantly change batteries.

The best of both worlds

The wind-tunnel-tested ATMOS 22 ultrasonic anemometer delivers the best of both worlds.It’s accurate at low wind speeds because there aren’t any moving parts that cause friction or fail. And it’s inexpensive, especially when you consider the low-energy design. Accuracy. Dependability. Affordability. You get all three with the ATMOS 22.

Wind measurement is now a breeze

The ATMOS 22 sonic anemometer was designed without moving parts, meaning there’s never any mechanical wear. No oiling or replacing bearings. And no recalibration required. Just reliability you can continue to count on.

Not only does its ultra-low power consumption make it ideal for long-term, remote installations, but its compact size makes it small enough to deploy inside canopies. And instead of having to make field visits to collect data and check sensor and system functions, you can monitor information in real time and download data using any internet-connected device by connecting the ATMOS 22 to a ZL6 data logger. Which not only saves you time, but provides worry-free operation and peace of mind.

Sounds like a smarter way to measure wind. Because it is

The precise accuracy, yet low-maintenance of sonic measurement. The low-cost of a regular anemometer, plus even lower power consumption. The ATMOS 22 ultrasonic anemometer was engineered to offer a wide range of advantages across the widest range of wind speed, all for an affordable price.
