Chengdu Hankang Information Industry Co., Ltd. is a high-tech enterprise focusing on scientific research and comprehensive technical services such as geographic information systems, disaster monitoring and early warning systems, and digital cities. Because the river water level monitoring requires low power consumption, digital interface output, fast response after power-on, and tolerance to large temperature differences in the natural environment, our company’s radar water level gauge was used in the disaster prevention project in Yibin City, Sichuan Province. Water level monitoring is carried out on the rivers and reservoirs around Yibin City. At present, the project has passed the inspection and acceptance of Sichuan Water Resources Bureau.
