Compared with the traditional mechanical wind speed and wind direction transmitter, the ultrasonic wind speed and direction indicator wind direction transmitter has the following four advantages:
1. No inertia measurement, no start wind speed limit, zero wind speed work, 360° omnidirectional no angle limit, can obtain wind speed and wind direction values at the same time;
2. It adopts an integrated structure design, with no moving parts as a whole, and the shell is made of engineering plastic material, which has little wear and long service life;
The third is the use of random error recognition technology, which can also ensure low discrete errors of measurement under strong winds and make the output more stable;
Fourth, the equipment does not require on-site calibration and maintenance;
Ultrasonic wind speed and direction indicator is equipped with four ultrasonic probes pointing down at the top of the device. They can send and receive ultrasonic waves in a two-dimensional plane. The measured wind speed is calculated by the built-in microprocessor based on the time difference of ultrasonic waves propagating in the air. With the value of wind direction, the data is uploaded to the monitoring center or cloud platform through the concentrator in 4G/GPRS communication mode for users to view.
