Real-time and accurate monitoring of wind speed and direction is a core requirement in weather forecasting, production safety, new energy utilization, scientific research and exploration, and other fields. As an iteratively upgraded professional wind measurement equipment, the Type 2 ultrasonic wind speed and direction meter abandons the inherent shortcomings of traditional mechanical structures and adopts the core technology of ultrasonic time difference. With the advantages of no wear, high precision, and all-weather adaptability, it realizes three-dimensional monitoring of wind field parameters. It has become the preferred intelligent equipment for various industries from fixed sites to mobile operations, providing efficient and reliable data support for wind condition analysis and decision-making.
1. Core technical principles: Ultrasonic sensing enables contactless and precise measurement

The core of the Type 2 ultrasonic wind speed and direction meter relies on the principle of ultrasonic time difference measurement to achieve contactless and accurate capture of wind speed and wind direction. The device has multiple sets of built-in ultrasonic probes. By alternately transmitting and receiving ultrasonic signals, the time difference of sound waves propagating in the air is used to calculate the airflow speed. When propagating in the downwind direction, the sound wave speed superimposes the wind speed. When propagating in the upwind direction, the sound wave speed offsets part of the wind speed. Through the difference calculation and vector analysis of multiple sets of signals by the microcontroller, the wind speed value and wind direction angle are accurately output. Compared with the traditional three-cup mechanical structure, this technology does not require moving parts, fundamentally eliminating problems such as mechanical wear and starting wind speed limitations. It also supports 0-360° full-angle measurement without dead angles. Combined with acoustic phase compensation technology, it can capture subtle wind speed changes as low as 0.01m/s, with a response speed as fast as milliseconds.

The device has a built-in intelligent calibration algorithm that can compensate for the effects of temperature and humidity on the propagation speed of sound waves in real time. Some models can also output acoustic temperature data simultaneously to further improve measurement stability in complex environments. Through all-solid-state design and digital signal processing, full-link automation from signal collection, calculation and analysis to data output is realized. The measurement accuracy and long-term reliability are greatly improved compared to traditional models.
