In order to take into account the water resistance of the displacement sensor, the displacement sensor is typically placed on top of the standpipe, where the weight of the float 11 is greater than the maximum pulling force pulling the displacement sensor 13, i.e. the weight of the float can pull the flexible rope to make the displacement sensor 13 reach the maximum measurement range. The standpipe can be provided with scale marks for displaying the height of the water level.
Preferably, a detection device for detecting the state of the barrier gate can be connected to the telemetering terminal.

For this purpose, a locating device is connected to the telemetry terminal. And the telemetering terminal 3 processes the acquired water level information and position data in real time and uploads the processed water level information and position data to the emergency management platform through a wireless network.
A water level sensor is arranged at the lowest point of a lower tunnel channel, a barrier gate 4 is arranged at an inlet and an outlet of the tunnel, an information display device 5 is arranged above the tunnel, water level change data are collected and processed in real time through a remote measuring terminal and uploaded to an emergency management platform of a city, when the water level is higher than a dangerous value, the barrier gate is immediately closed, and the height of the water level of the tunnel is displayed on the information display device; when the water level is lower than the dangerous value, the barrier gate is automatically opened.
