Buy a ultrasonic anemometer for wind online, with 0-40 m/s air velocity and 0-360° wind direction measurement. The wind speed and direction sensor use ultrasonic sound waves to measure wind velocity. Ultrasonic wind speed & direction anemometer uses a low-power chip, power consumption is only 0.2W, which is especially suitable for solar or battery-powered applications that require low power consumption.
Concealed probe design
High strength ABS body
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.
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.
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: What is an ultrasonic anemometer?
Ultrasonic anemometers measure wind speed by detecting the difference in time taken for an ultrasonic pulse to travel in each direction between pairs of transducers caused by movement of the air. This method allows accurate measurement even at low wind speeds as there is no mechanical inertia to overcome.
