In this paper, development of a sensor using a circular disc for air velocity measurement based on the drag force equation is proposed. The air velocity measurement sensor is basically designed with a load cell in order to determine the drag force. The circular disc is used for creating a drag force, and by using load cell, the drag force that acts on the circular disc is measured. As the circular disc's drag coefficient can be considered constant at Reynolds numbers between 10³ and 10⁶, it can be possible to obtain the explicit equation of drag force. The remaining components of drag force equation are obtained by measurement. The proposed air velocity measurement sensor is characterized by wind tunnel measurements. All measurements were performed in an ISO/IEC 17025 accredited calibration laboratory – the Wind Tunnel of Turkish State Meteorological Service. The characterization measurements were performed at air velocities between 1 m/s and 20 m/s. The correction factors were calculated and a calibration curve for the proposed air velocity measurement sensor was obtained. The calibration curve's linearity was higher than 0.99 and a comparison the results from a Micromanometer with Pitot-Tube shows that for the designed working range, the sensor has an acceptable performance for time-averaged air velocity measurements according to the requirements of the World Meteorological Organization.

本文提出了一种基于拖曳力方程的圆盘式风速传感器的开发方法。空气速度测量传感器基本上设计有一个称重传感器，以便确定阻力。圆盘用于产生拖曳力，并通过使用称重传感器来测量作用在圆盘上的拖曳力。由于圆盘的阻力系数在10 ³和10 ⁶之间的雷诺数下可以认为是恒定的，有可能获得明确的阻力方程。阻力方程的其余分量可通过测量获得。所提出的空气速度测量传感器的特征在于风洞测量。所有测量均在经ISO / IEC 17025认证的校准实验室–土耳其国家气象局的风洞中进行。表征测量是在1 m / s至20 m / s的空气速度下进行的。计算校正因子，并获得所建议的风速测量传感器的校准曲线。校准曲线的线性度高于0.99，将Micromanometer与Pitot-Tube进行比较的结果表明，在设计工作范围内，
