Introduction to the terminology and definition of electromagnetic flowmeter measurement

Terms and definitions for electromagnetic flowmeter measurements
1) Standard uncertainty The uncertainty of the measurement result is expressed by the standard deviation.
2) (Standard Uncertainty) A method of statistical analysis of a series of observations to calculate the standard uncertainty.
3) (Standard Uncertainty) The Class B calculation method is different from the method of performing statistical analysis on a series of observations to calculate the standard uncertainty.
4) Synthetic standard uncertainty The standard uncertainty of the measurement results obtained from the values of the other ones is equal to the positive square root of the sum of the items, and each term is based on how the measurement results vary with the amount of winding. The variance or covariance of other quantities that are weighted.
5) Extended Uncertainty Define the amount of the measurement result interval, and expect to reasonably give the measured value a higher confidence level interval.
6) Coverage factor To obtain extended uncertainty, as a numerical factor that synthesizes the standard uncertainty multiplier.
