According to the present invention, provided are a stopping rod and a location measurement system in a fluid tank, forming a groove inside a cylinder of the stopping rod to allow pressure to differ according to a position of the stopping rod, thereby figuring out the position of the stopping rod. The stopping rod located inside a fluid tank includes the cylinder and a piston located inside the cylinder. The cylinder includes a cylinder body. A cylinder groove opened toward a hole in which the piston is provided in the longitudinal direction is formed inside the cylinder body. The pressure of the upper side of the cylinder differs according to the position of the piston. |
