Msensor Sensor - Tunnel Bottom Settlement and Deformation Monitoring Static Level Instrument


  

  Within a range of 150 meters into the tunnel at the left and right tunnel entrances, static level gauges are evenly distributed at 10-meter intervals on the tunnel floor and the side lining walls to monitor tunnel settlement and vertical deformation, as shown in the figure below.
