Abstract:
This study describes the development of a Monte Carlo based numerical analysis method to determine the
instrumental uncertainty of dimensional measurements with wave gauges. The paper presents the adopted
calculation procedure, namely, the mathematical model used in the determination of the amplitude and fre-quency of the wave gauge measurements. The results show a relative expanded (95%) target instrumental
measurement uncertainty between 0.067 7 m and 0.068 2 m for the amplitude and between 0.592 4 Hz, and
0.592 8 Hz for the frequency.
The study carried out allows for the conclusion that the use of a Monte Carlo-based numerical approach is
suitable to evaluate the measurement uncertainty of parameters fitted to wave displacement analysis.
