Systems and methods for testing pump flow rates

摘要

The system and methods obtain a set of multiple data samples and derive an average of the data samples in the set (SETAVE). The systems and methods derive a standard deviation for the data samples in the set (SETSTD). The systems and methods compare each of the data samples to SETSTD and either reject the data sample, if the absolute difference between the data sample is greater than or equal to k * SETSTD, where k is a selected value greater than zero, or retain the data sample, if the absolute difference between the data sample is less than k * SETSTD. The systems and methods repeat the foregoing steps until the absolute difference between every data sample remaining in the set is less than k * SETSTD. The systems and methods then derive a filtered average for the set FSETAVG, where FSETAVE is the SETAVG for the data set in which the absolute difference between every data sample remaining in the set is less than k * SETSTD. The systems and methods find application in the calculation of pump flow rates, particularly using gravimetric calculation techniques.
