SISCO ultrasonic anemometer for 0~70 m/s wind speed and 0~360° wind direction measurement. Wind direction measurement angle 0~360 degree, output potentiometer signal. This ultrasonic wind sensor is customized to be completely compatible with Davis Vantage Pro2 series weather station, can be directly connected to Davis ISS via RJ11 port.
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: How does ultrasonic sensor measure wind speed?
The main wind measurement methods used in ultrasonic sensors are the vortex and the time-of-flight (TOF). The vortex method determines wind speed by measuring the frequency of the vortex, based on the proportional relationship between the average flow velocity and the eddy current frequency.
