    • 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.
    • 估计从包括储罐的流体分配系统分配流体的多个分配计量器中的每一个的测量精度的方法包括在多个时间间隔期间测量在多个分配计量器中分配的流体的体积, 通过多个分配仪器同时分配流体; 测量在所述多个时间间隔期间的每个期间从所述储存箱分配的流体的体积; 并且通过对从储罐分配的流体的测量体积进行回归分析,计算通过每个分配计量器分配的流体体积的一部分,其等同于通过 在多个时间间隔的每个期间,多个分配计量器。 通过多个分配仪器分配的流体的测量体积的总和的分数等于在多个时间间隔上平均分配的每个分配计量器的测量体积的分数之和。
