摘要
A system and method to detect and quantify integration errors in a transit time ultrasonic flow meter uses dissimilar integration methods or schemes employed simultaneously. In a preferred embodiment, a number of chordal paths are arranged in a single meter body such that at least two dissimilar chordal integration schemes can be used to determine the flow rate. At least one of the chordal paths is common to both integration schemes. The total number of chordal paths needed in any chordal measurement plane is less than the sum of the chordal paths used in each of the integration schemes (as is the sum of the planes), thereby reducing hardware requirements.
