Abstract The GUM method and the adaptive Monte Carlo method were used to evaluate the measurement uncertainty of the level 0.005 pressure type water depth measuring instrument verification device, and the GUM method was verified by the adaptive Monte Carlo method. The results showed that the pressure measurement model was more complicated, both methods were suitable for evaluating the measurement uncertainty, and when the effective number of standard uncertainty was taken one bit, the GUM method was verified at each detection point. It was very important to choose the reasonable value of the numerical tolerance. In the actual measurement, it should be selected according to the accuracy of the measuring instrument and the requirements of the measurement results.
