由东煤公司主持、沈阳煤矿设计院和沈阳民航管理局通讯总站共同开发研制的ALS-I型超声波料位检测系统于1991年5月8日在沈阳煤矿设计院通过鉴定.ALS-L型超声波料位检测系统可以保证料位检测的需要;可以代替国内传统的电极式、电容式、重锤式料位检测装置;可以代替进口同类产品,可以广泛应用于煤炭、冶金、电力、化工.粮食、建材等行业的大型 The ALS-I ultrasonic level detection system jointly developed by Shenyang Coal Mine Design Institute and Shenyang Civil Aviation Administration Communication Terminal was approved by Shenyang Coal Mining Design Institute on May 8, 1991. ALS-L ultrasonic wave Material level detection system can ensure the need of material level detection. It can replace the traditional electrode type, capacitance type and hammer type material level detection device in China. It can replace imported similar products and can be widely used in coal, metallurgy, electric power and chemical industry. , Building materials and other large industries
