In June 2013, our company received an invitation from the North Economic Development Zone of Rizhao City to conduct on-site investigations at the Chaohe Town Sewage Treatment Plant (Jingyuan Sewage Treatment Plant) in Wulian County. After commercial negotiations, our company was successfully selected to undertake the installation and commissioning of level gauges, including ultrasonic level gauges, radar level gauges, and magnetic flap level gauges;

To undertake the installation and commissioning of the self-control system, our company used Siemens S7300 to monitor the instruments, pumps, valves, fans, and other equipment throughout the entire factory area. The project was completed in November 2014.
