摘要
在这封信中,我们报告了利用基于视觉的传感方法开发粘度计的情况。实验装置包括一个圆柱形透明容器,容器底部有一根毛细管,容器后面有一块白色纸板,纸板上有一条垂直黑线。当液体样品流经毛细管时,原来的黑线会重新出现在半月板上方,并增加其长度,而半月板下方的折射线则会缩短。摄像头与树莓派(Raspberry Pi)结合使用,可根据半月板上方垂直线长度的变化测量流动时间(FT),从而根据普瓦休伊液体流动方程估算出粘度。该系统用于测量 20 °C 和 30 °C 温度下的粘度。实验结果表明与测试样品的标准粘度值十分吻合。所提出的系统具有多个优点,包括设计简单、成本低、非侵入式操作、自动测量流动时间以及通过实时处理提高响应速度。它适用于测量透明牛顿液体的粘度。
A Novel Vision-Based Approach for Estimating Viscosity and Concentration of Transparent Liquids
In this letter, we report the development of a viscometer by utilizing a vision-based sensing method. The experimental arrangement includes a cylindrical transparent container with a capillary tube at its bottom and a white cardboard with a vertical black line positioned behind the container. As the liquid sample flows through the capillary tube, the original black line reappears above the meniscus increasing its length, while the refracted line below the meniscus shortens. A camera in association with a Raspberry Pi is used to measure the flow time (FT) from the changing length of a vertical line above the meniscus, which estimates the viscosity from Poiseuille's equation of liquid flow. The system is utilized for viscosity measurements at temperature of 20 °C and 30 °C. Experimental results demonstrate well agreement with standard viscosity values of the test samples. The proposed system offers several merits, including simple in design, low cost, noninvasive operation, automatic flow time measurement, and improved response time facilitated by real-time processing. It is suitable for measuring the viscosity of transparent Newtonian liquids.
