PURPOSE: A panel angle measurement system for a pneumatic movable weir is provided to regulate an angle to a base plate of a panel in real time by promptly and accurately measuring an angle between the base plate and the panel. CONSTITUTION: A panel angle measurement system for a pneumatic movable weir comprises a tilt sensor (1000) and a control unit. The tilt sensor comprises a pair of spring members (1200), a weight member (1300), a pair of acceleration members (1400), and a pair of sensing members (1500). The control unit receives angle information measured by the tilt sensor and controls the operation of a supply and exhaust system. The control unit receives angle data transmitted from tilt sensors, which are installed on every panel, or tilt sensors, which are installed on panels in a unit, compares the angle data with stored set angle data. Depending on the comparison results, the control unit controls the supply and exhaust system which is installed in a bladder in order to prevent drift current between panels or between panels in a unit.
