In aerospace, turbomachinery, automotive aerodynamics, and wind tunnel testing, accurate three-dimensional flow measurement remains a cornerstone of aerodynamic research. Yet, conventional high-end systems often come with complex configurations, costly maintenance, and price tags that exceed the budgets of many research teams. Addressing this challenge, Windtuner has introduced its Five-Hole Probe Anemometer, a compact and affordable instrument that delivers research-grade precision at a fraction of the typical cost—providing an accessible, high-value solution for 3D flow field measurement.
Breaking the Cost Barrier in Flow Measurement
The accurate capture of three-dimensional velocity components and pressure distribution is essential to understanding aerodynamic behavior and optimizing structural design. However, imported measurement systems can cost tens or even hundreds of thousands of dollars, posing a significant barrier for university laboratories, small R&D centers, and startup innovators. Moreover, limited algorithm access and service constraints often hinder such systems from adapting to domestic testing needs. Windtuner’s development goal was therefore clear: to make high-precision flow field measurement attainable without compromising accuracy or reliability.
A Balanced Fusion of Performance and Affordability
Building on more than a decade of experience in aerodynamic measurement and control, Windtuner developed a next-generation Five-Hole Probe Anemometer capable of measuring airflow pressure, velocity, and direction simultaneously. With an accuracy better than 0.5%FS, velocity accuracy within 1 m/s, and angular accuracy of ±1°, the instrument delivers performance comparable to top-tier international systems—yet at a price point of only several tens of thousands of RMB. For many researchers, this represents an unprecedented balance between cost and capability.
Intelligent Design with Built-in Algorithmic Precision
At the heart of the Windtuner Five-Hole Probe Anemometer is a fully integrated hardware–software architecture. Advanced interpolation and compensation algorithms automatically correct environmental temperature and pressure variations, while high-sensitivity sensor modules maintain long-term stability and repeatability. The built-in real-time data processing unit reconstructs 3D velocity vectors and pressure fields instantly, eliminating the need for external computing modules. This streamlined integration not only enhances testing efficiency but also minimizes signal interference and cumulative error, enabling researchers to focus on analysis rather than equipment setup.
Expanding the Possibilities of Research and Application
Designed for flexibility, the system has proven reliable in a wide range of scenarios—from aircraft attitude and velocity testing to turbomachinery flow field analysis and wind tunnel experiments. Its compact size and robust structure allow seamless integration into both academic and industrial test setups, while the intelligent communication interface simplifies data collection and synchronization. Whether for visualizing vortex structures, evaluating aerodynamic interference, or conducting educational experiments, Windtuner’s anemometer empowers users to achieve high-quality results with significantly reduced cost and complexity.
By integrating precision sensing, intelligent algorithms, and engineering-grade reliability, Windtuner has redefined the economics of three-dimensional flow measurement. The Five-Hole Probe Anemometer exemplifies how innovation in measurement and control can make advanced aerodynamic testing more accessible—helping research teams shorten development cycles, validate designs more efficiently, and accelerate the translation of ideas into results.
