A method of estimating the measuring accuracy of each of a plurality of dispensing meters which dispense fluid from a fluid dispensing system including a storage tank includes measuring a volume of fluid dispensed through each of the plurality of dispensing meters during a plurality of time intervals during which fluid is simultaneously dispensed through the plurality of dispensing meters; measuring a volume of fluid dispensed from the storage tank during each of the plurality of time intervals; and calculating a fraction of the volume of fluid dispensed through each of the dispensing meters by performing a regression analysis with respect to the measured volume of fluid dispensed from the storage tank equated with a fraction of a sum of the measured volumes of fluid dispensed through the plurality of dispensing meters during each of the plurality of time intervals. The fraction of the sum of the measured volumes of fluid dispensed through the plurality of dispensing meters equals the sum of the fractions of the measured volumes of fluid dispensed through each of the dispensing meters on average over the plurality of time intervals.

La présente porte sur un procédé d'estimation de la précision des mesures de chacun des compteurs de débit qui distribuent un fluide depuis un système de distribution de fluide comprenant un récipient de stockage. Ce procédé consiste à mesurer un volume de fluide distribué dans chacun des compteurs de débit au cours de plusieurs intervalles de temps pendant lesquels le fluide est simultanément distribué dans chacun des compteurs de débit; à mesurer un volume de fluide distribué depuis le récipient de stockage pendant chaque intervalle de temps; et à calculer une fraction du volume de fluide distribué dans chaque compteur de débit par une analyse de régression par rapport au volume mesuré de fluide distribué depuis le récipient de stockage égal à une fraction d'une somme de volumes mesurés de fluide distribué dans chacun des compteurs de débit au cours de chaque intervalle de temps. La fraction de la somme des volumes mesurés de fluide distribué dans chacun des compteurs de débit correspond, en moyenne, à la somme des fractions de volumes mesurés de fluide distribué dans chacun des compteurs de débit sur l'ensemble des intervalles de temps.
