The infrared liquid level meter is based on the interaction between the infrared sensor and the liquid, and determines the height of the liquid by measuring the reflection of the infrared light emitted by the infrared sensor on the surface of the liquid. By utilizing the principle of infrared reflection, accurate measurement of liquid level is achieved through non-contact detection, avoiding the error problems that may occur with traditional liquid level meters and ensuring the accuracy of measurement results. It can be widely used in various storage tanks or pipeline systems, and is suitable for industries such as chemical, petroleum, food, pharmaceutical, etc.

The laser profilometer combines a linear laser light source with a high-speed industrial camera to obtain cross-sectional contour images of the measured object, and extracts the contour using image processing technology. According to the principle of triangulation, calculate the physical coordinate information of the contour. In addition, the laser profilometer can also achieve continuous measurement and synthesis of object contours through motion control, forming 3D point cloud data of object appearance contours. Data can not only be used for measurement and calibration in product design and manufacturing processes, but also play an important role in fields such as industrial manufacturing and quality control.

Millimeter wave radar, as an emerging sensor technology, uses high-frequency and short wavelength electromagnetic waves to achieve high-precision target detection, distance measurement, and velocity estimation. Compared with other sensors, millimeter wave radar performs well in complex scenes and is not affected by factors such as light, rain, and snow. It is suitable for target recognition and positioning in various environments. Millimeter wave radar can not only provide position and distance information of targets, but also detect their speed and direction, providing more environmental perception data information. In addition, radar can be easily integrated into existing equipment or systems without the need for complex modifications or installation processes, enabling rapid deployment and application.
