PROBLEM TO BE SOLVED: To measure the height of a liquid level in the circumference of a structure existing on the surface of a liquid with a simple configuration without affecting an original waveform.SOLUTION: A liquid level measurement system includes: multiple electrode pairs; and a measurement unit 20 connected to them. Four sets of vertically elongate and thin film shape electrodes 11, 12 are paired (electrode pairs) and arranged on a side surface of a marine vessel body 100. A voltage is applied to the respective electrode pairs, and characteristic changes between the electrodes 11, 12 are detected by the measurement unit 20, so that the heights of a sea level 201 at places of the respective electrode pairs are measured. The measurement unit 20 includes a detection control circuit 30 and a calculation circuit 40. The electrodes 11, 12 are arranged to partially sink into the water in the length direction, i.e. to allow the sea level 201 to enter within the range of respective lengths in a vertical direction (a depth direction). |
