Hefei High-Speed Railway Adopts Fuzhou Dayu Solar-Powered Wireless Ultrasonic Level Gauge

The Fuzhou section of the Hefei-Fuzhou high-speed railway uses Fuzhou Dayu's solar-powered wireless ultrasonic level gauge to control the start and stop of water pumps.

During the construction of the Fuzhou section of the Hefei-Fuzhou high-speed railway, fire water tanks were installed in the tunnels, and Fuzhou Dayu's solar-powered wireless ultrasonic level gauge was used to monitor the water level. The level signal is then transmitted wirelessly to the pump house at the foot of the mountain. The control cabinet in the pump house can start the water pump to supply water based on the water level in the mountain fire water tank. When the water level reaches a certain height, the pump at the foot of the mountain stops working. In addition, the control cabinet in the pump house can set the upper and lower water level limits via the touch screen, and can also output signals to the RTU, which transmits them wirelessly to the railway bureau's backend system.
