HY-WTE Crossed Tunnel Ultrasonic Wind Sensor



Introduction


HY-WTE crossed type tunnel ultrasonic wind speed and wind direction detector is specifically designed for for the tunnel application, it’s working based on ultrasonic time-difference method, the two ultrasonic probes were installed on both sides of the tunnel wall and face to each other, when tunnel airflow passes between the two ultrasonic probes, the time difference between the round-trip times of the ultrasonic waves transmitted by each other is changed by airflow. By measuring the time difference, the airflow velocity is obtained.


Main Features

1. Cast aluminum body, anodized surface for harsh environments in the tunnel

2. Large sampling area, accurately reflect the air flow rate in tunnel

3. Ultrasonic measurement free from influence of ambient temperature

4. Non-contact detection, no moving parts, free of maintenance
