Mechanical vs Ultrasonic Wind Sensors: What's the Difference and Where Does FT's Acu-Res® Fit In?

Reliable wind measurement is critical for marine and offshore operations. Traditional mechanical anemometers use rotating cups or propellers and a vane to measure wind speed and direction, but moving parts are prone to wear, debris and ice build-up, increasing maintenance and risk of failure in harsh conditions. 

Time-of-Flight (ToF) ultrasonic sensors calculate wind from sound travel time along open paths, which can be disrupted by rain, spray and environmental factors.

FT Technologies' Acoustic Resonance (Acu-Res®) technology resonates sound waves within a small protected cavity, delivering reliable, high-quality measurements even under vibration, rain or platform motion, with excellent robustness against salt spray, ice, rain and shock. Acu-Res® wind sensors provide reliable and accurate wind speed, direction, temperature, pressure, inclination and compass heading.
