Overview
Time-of-flight ultrasonic measurement of wind speed and direction with no moving parts, no start-up threshold and no field calibration, outputting both values simultaneously. Unlike mechanical anemometers there is no bearing wear or inertia error, making it suitable for unattended long-term outdoor monitoring.
Features
- One-piece stainless steel housing, solid-state design, corrosion and weather resistant.
- No start-up threshold, measurement from 0 m/s, full 360° coverage.
- High accuracy, 1 s response, low power; heated version for cold climates.
- Can run from a solar panel and battery for remote wireless transmission.
