Overview
The ultrasonic anemometer is is a kind of measuring instrument which uses the time difference of ultrasonic wave in the air to measure the wind speed and direction. It can accurately and quickly detect the air velocity of 0-60 m/s and wind direction of 0-360°. The air velocity and direction meter adapts to complex weather conditions. The surface has preservative treatment, strong anti-interference, automatic heating anti-frozen.

Ultrasonic Wind Speed & Direction Anemometer Dimension (Unit: mm)

Ultrasonic Wind Speed & Direction Anemometer Installation
There are rotary adjustable mounting holes at the bottom of the ultrasonic anemometer.
When installing the wind sensor, make sure the indicator on the anemometer complies with the geographic north.

Application
Small ultrasonic wind speed and direction anemometers are widely used in the measurement of wind speed and direction in the fields of meteorology, ocean, environment, airports, ports, laboratories, industry, agriculture and transportation.

FAQs
Q1: How do you ensure accuracy of anemometer?
A1: To make sure anemometers are reliable and precise, they should be regularly calibrated. This is the procedure of checking the accuracy of a measuring instrument – as well as the adjustment to align it with the standard. The process allows equipment to produce more accurate results than would've otherwise been possible.
Q2: What affects an anemometer?
A2: The higher the wind speed, the more power is required to keep the wire at a constant temperature. Wind speed can also be determined by measuring air pressure. (Air pressure itself is measured by an instrument called a barometer.) A tube anemometer uses air pressure to determine the wind pressure, or speed.
Q3: Does an anemometer measure wind direction?
A3: An anemometer looks like a weather vane, but instead of measuring which direction the wind is blowing with pointers, it has four cups so that it can more accurately measure wind speed. Each cup is attached to the end of a horizontal arm, each of which is mounted on a central axis, like spokes on a wheel.
Tips: Are ultrasonic anemometers accurate?
Yes, because ultrasonic wind speed measurement sensors have no moving parts, the measurements are immediate and extremely precise.
