Title: AN APPARATUS AND METHOD OF PROCESSING DATA TO IMPROVE THE PERFORMANCE OF A FLOW METER
Abstract:
An apparatus and method of processing flow meter data to filter out signal noise is provided. The method includes defining the flow meter data is a k-ω plane, wherein the k-ω plane includes a first k-plane quadrant separated from a second k-plane quadrant by a predetermined axis. The flow meter data includes a first data set disposed within the first k- plane quadrant and a second data set disposed within the second k-plane quadrant. The first data set and the second data set are disposed symmetrically about the predetermined axis and subtracting the first data set from the second data set to obtain a resultant data set.
