PURPOSE:To make accurate measurement with simple constitution by vertically moving a connecting annular tape having a magnet in correspondence to a float sealed with a magnet. CONSTITUTION:A float magnet 3 is floated on the tank liquid 2 in a tank communicating column 1 communicated with a tank, and in accordance with the vertical movement thereof, an indicating magnet 4 on the outer side is vertically moved cooperatively therewith. When the magnet 3 is moved vertically with a change in the liquid level in the column 1, the magnet 4 attracted thereto moves vertically, and in accordance with this, an inner annular tape 5 rorates around pulleys 9. As a connecting part 7 moves vertically, an outer annular tape 6 totates in the opposite direction. As a result, an indicating part 8 corresponds to the magnet 4 and indicates the change in the liquid level. A self position transmitter is mounted to the part 8 to perform measurement in a remote place. |
