Shandong Jingzhi Liquor Industry Co., Ltd. is a national wine-making backbone enterprise, a large-scale wine-making enterprise in Shandong Province, a top 50 liquor production enterprise in China, and a large-scale sesame-flavor liquor production enterprise in China. When they started the blending factory, they established more than 90 storage tanks to store the original wine and the first-grade Jingzhi wine after blending. In order to monitor the level of wine in storage tanks, we compared equipment provided by many companies, including hydrostatic level gauges, magnetic flap level gauges, and radio frequency admittance level gauges. Because of our explosion-proof ultrasonic level gauge , the first is non-contact measurement, without contact with the original wine; the second is that the measurement is not affected by changes in the concentration and density of the original wine; the third is that the overall use and maintenance cost is low. Finally purchased our company's explosion-proof ultrasonic level gauge to measure. After more than 2 years of use, it meets the original design requirements.
