Note x The calibration and measurement capability Ucmc includes all significant contributions except the
meter's contributions, It is the calibration facility's expanded uncertainty excluding contributions
from the calibrated Venturi tube, See also Measurement UnceftainÇ on page 4.

M EASU REM ENT UNCERTAINTY

The coverage factor k is 2 in all calculations of expanded uncertainty.
The reported expanded uncertainty of measurement is stated as the standard uncertainty of measurement
multiplied by the coverage factor k such that the coverage probability corresponds to approximately 95 o/o.
