Low-power radar level meter

Low-power radar level meter is a 60GHz Frequency Modulated Continuous Wave (FMCW) radar product. It offers a maximum measuring range of up to 5 meters and a blind zone of less than 5 cm. Operating at a higher frequency with a wider bandwidth, it delivers higher measurement accuracy. The device is battery-powered and supports wireless transmission, including LoRa, LoRaWAN, Wi-Fi, and Cat 1 (4G).

When Baijiu base liquor is stored in ceramic jars, sealing issues may indeed arise. However, this characteristic is often ingeniously utilized in traditional craftsmanship to achieve a unique aging effect. The microscopic pores in the ceramic allow trace amounts of oxygen to enter, promoting reactions such as esterification and hydrolysis, which facilitate the maturation of the liquor (e.g., generating esters to enhance aroma). Many high-quality Baijiu varieties (such as sauce-aroma type) rely precisely on this process to develop their complex flavor profiles. If the sealing of the ceramic jar is substandard (e.g., due to non-durable sealing materials or uneven density of the clay), it may lead to excessive evaporation of alcohol and flavor compounds, thereby compromising the liquor quality.

Our low-power FMCW radar level meter, integrated with our wireless transmission and management platform, forms a real-time monitoring system for base liquor. When excessive evaporation of the base liquor is detected, the device immediately reports the alert to the platform via wireless transmission. The platform then notifies the relevant personnel to re-seal the jars. The system architecture is as follows:
