Accurate wind measurement, choose - ultrasonic wind speed and direction sensor

1、 Product Introduction

Ultrasonic wind speed and direction sensor, also known as ultrasonic anemometer or ultrasonic wind speed and direction meter, is a wind speed and direction measurement instrument developed based on the principle of ultrasonic waves. It uses the transmitted sound wave pulses to measure the time or frequency (Doppler transform) difference at the receiving end to calculate wind speed and direction. As a professional enterprise engaged in research and development, production, and sales of micro meteorological instruments, our company has been committed to promoting the application of micro meteorological instruments and meteorological environment solutions. With a complete production chain, strong technical team, and comprehensive marketing team, we have developed and produced meteorological products such as ultrasonic anemometers, five element micro meteorological instruments, six element micro meteorological instruments, and small automatic meteorological stations. These products have been widely used in meteorological monitoring, urban environmental monitoring, wind power generation, navigation ships, airports, bridges, tunnels, and other fields. Our customers are spread all over the country and have achieved good social and economic benefits.

Compared with traditional micro meteorological instruments, our products overcome the need for high-precision timers and avoid measurement inaccuracies caused by sensor startup delays, demodulation circuit delays, and temperature changes.

The WQX2 ultrasonic wind speed and direction sensor innovatively achieves wind speed and direction through a highly integrated structure, which can realize 24-hour continuous online monitoring of outdoor meteorological parameters. The two parameters are output to the user at once through a digital communication interface.

It can be widely used in urban environmental monitoring, wind power generation, meteorological monitoring, bridges and tunnels, navigation ships, airports and other fields, without the need for on-site maintenance or calibration.
