In this paper, to improve the detecting accuracy of a servo-type wave gauge, first a newly developed testing apparatus of wave gauge is reported. Using this testing apparatus, the testing accuracy is shown to be ±0.01mm. By introducing a micro-computer system, the time needed to test is shortened. By recording the data automatically no personal error is conceivable.
The detecting accuracy of various shapes of surface detectors are experimentally compared. The wave level error due to the change of water conductivity varying with water temperature and water quality is calculated. Testing the compensative method of water conductivity confirmed that a successful compensation is achieved. As the result of testing the servo-type wave gauge, the detecting accuracy is improved to be within ±0.05mm.
