Wind speed and direction measurement system

Introducing our Low-Drag Smart Tether System—the future of fluid speed and direction measurement. Experience unmatched accuracy, energy efficiency, and reliability, revolutionizing how we perceive and utilize wind data in the modern age.

The Need

In the realm of aerial technology, the demand for accurate, low-cost wind monitors that are both scalable and efficient has never been higher. Traditional methods, such as pitot tubes and cup-and-vane anemometers, are marred by issues like icing vulnerability, high energy consumption, and unsuitability for aerial applications. Moreover, existing thermal and ultrasonic anemometers suffer from power consumption challenges and non-aerodynamic designs. There is a critical need for a solution that offers precise wind speed and direction measurements without compromising energy efficiency, aerodynamics, or accuracy.

The Technology

Introducing our groundbreaking Low-Drag Smart Tether System—a revolutionary advancement in the field of fluid speed and direction measurement. This innovative system comprises a specialized sleeve with an airfoil-shaped cross-section, a pressure sensor, and a Dyneema tether. The sleeve, designed for minimal drag, rotates about the tether's longitudinal axis when exposed to fluid flow. The pressure sensor, utilizing cutting-edge technology like strain-based, capacitive, or piezoelectric sensors, accurately measures the pressure exerted by air, enabling precise wind speed calculations. Additionally, a directional sensor, often a magnetometer compass or an angular encoder, provides cardinal orientation data. This comprehensive system offers unparalleled accuracy and energy efficiency, ensuring reliable measurements in various environmental conditions.
