No measurement is ever completely exact; there is always a degree of doubt about its accuracy. This degree of doubt is quantified by the uncertainty. The effects of measurement uncertainty manifest themselves across all industrial sectors, resulting in significant financial exposure. In the field of flow measurement, measurement uncertainty is particularly important when the fluid being metered is of high value where small errors in flow measurement could potentially cost the operator large amounts of money.
