PURPOSE: A leveling system for checking the twisting of a bridge is provided to monitor the twisting of the bridge in a real time by automatically and wirelessly transmitting data to an operator. CONSTITUTION: A leveling system for checking the twisting of a bridge comprises a leveling pipe(10), a water level measuring unit(20), a pressure sensor(30), a control unit(40), and a radio transmitter(50). The leveling pipe comprises a horizontal pipe(11) and a vertical pipe(12). The water level measuring unit measures the fluid level of the leveling pipe. The pressure sensor measures the inside pressure of the leveling pipe. The control unit calculates the relative height change rate of the both ends of an upper plate. The control unit wirelessly transmits the relative height change rate of the calculated upper plate both ends using the radio transmitter. The radio transmitter is connected to the control unit.
