3D Ultrasonic Anemometer – 3 Axis RS485 Output

3D Anemometer

Advanced All-Metal Ultrasonic Wind Measurement for Challenging Environments

Overview

Our 3-axis ultrasonic wind sensor is engineered for high-precision measurement of both horizontal and vertical wind components (U, V, W) using advanced ultrasonic transit-time technology. Built with a full metal housing and zero moving mechanical parts, it delivers outstanding durability, virtually maintenance-free operation, and excellent resistance to contamination and weathering. It’s ideal for demanding applications such as urban meteorological stations, wind-farm monitoring, bridge & tunnel airflow measurement, marine/port installations, airport wind assessment, and more. 

3D Ultrasonic Anemometer Measuring Principle

The instrument uses three pairs of ultrasonic transducers spaced at fixed intervals. Each pair alternately emits and receives ultrasonic waves in both upstream and downstream directions. By accurately measuring the ultrasonic flight time difference caused by air movement, the device computes the wind-speed components along X, Y and Z axes. From these components it derives the magnitude of the wind vector (speed) and the wind direction—both horizontal (azimuth) and vertical (elevation).
This method offers higher reliability and faster response than traditional mechanical sensors and is virtually immune to icing or fouling.

3D Ultrasonic Anemometer Key Technical Specifications

Monitoring elements synthetic wind speed, horizontal wind direction, vertical wind direction, X/Y/Z axis vector wind speed   

Why Choose It? 

True vector wind measurement — captures wind speed and direction along all three axes (X/Y/Z), enabling fuller insight into flow patterns and turbulence. 

No moving parts = minimal inertia, rapid response — Because there are no cups, propellers, or vanes, the sensor reacts instantly to gusts, sudden changes and vertical drafts. 

Robust all-metal construction — Withstands harsh environments, extreme temperatures, high humidity and airborne contaminants. 

Reduced wind resistance design — The streamlined structure minimizes measurement interference while maximizing longevity and stability in high-wind or turbulent conditions. 

Wide range of applications — Suitable for environments where typical 2-D anemometers may struggle (e.g., complex urban terrain, coastal sites, bridge decks). 

Compatibility & ease of integration — Standard RS-485 communication via Modbus enables seamless connection to PLCs, SCADA systems, weather station dataloggers and IoT platforms.

Installation & Wiring Guidelines

Red: Power input (positive) 

Black: Power input (negative) 

Yellow: RS-485+ 

Blue: RS-485– 

Note: Please refer to the actual cable labels when wiring.

Mounting Recommendations 

Ideal mounting: top of meteorological mast or stand-alone pole, at least 2 m above local obstructions (trees, buildings, equipment). 

Avoid mounting near radar or high-frequency emitters. 

Ensure free air flow around the sensor—no nearby obstructions within twice the height of the sensor mounting point. 

Align the 0° reference mark (marked on top of the instrument) to true north before tightening bolts. Secure with four stainless-steel bolts to the mounting bracket. 

Use the aviation-style plug at the base; ensure proper strain relief of the cables to prevent motion or damage. 

Applications & Use Cases 

Wind farms / renewable energy: real-time 3-D wind vector data improves turbine control, wake modelling and asset protection. 

Urban meteorology & environmental monitoring: captures complex wind flows, turbulence and vertical drafts in built-up areas. 

Bridges, tunnels & high altitude sites: monitors airflow and wind loads for structural health, safety and compliance. 

Marine & port operations: measures wind in three dimensions for vessel guidance, mooring operations and navigational safety. 

Aviation / airports / helipads: vertical wind shear and gust detection improve flight safety and operational planning.
