Ultrasonic Wind Speed and Direction Sensor. Using the transmitted acoustic pulse, the phase difference of the receiver is measured to calculate the wind speed and direction. The wind speed and direction Data are measured and Output at a 4 to 20mA Signal
WS303U is a precision ultrasonic wind speed and direction sensor and has no moving parts .It measure ultrasonic phase difference to calculate the wind speed and direction. The sensor can measure the instantaneous value of wind speed and direction at the same time. The unit has also a built-in electronic compass. It is widely used in the fields of commercial meteorology.
