1. A method of detecting one or more integration errors, the method being performed by at least one set of computational electronics including a non-transitory computer readable medium with computer instructions stored thereon executed by a processor, the method comprising steps of:
receiving ultrasonic signals from transducers in a meter body of a flow meter associated with a conduit, the ultrasonic signals traveling along a plurality of chordal paths across the conduit wherein at least one of the plurality of chordal paths lies in a discrete chordal measurement plane across the conduit and determining a velocity on each chordal path in the flow meter;
executing a first chordal integration scheme in the flow meter using at least one of the plurality of chordal paths and a second different chordal integration scheme in the flow meter using the at least one of the plurality of chordal paths, the first chordal integration scheme being an even numbered chordal integration scheme and the second different chordal integration scheme being an odd numbered integration scheme, wherein at least one of the first chordal integration scheme and the second chordal different integration scheme are used with the velocity on each chordal path;
applying first weighting factors to the first chordal integration scheme, wherein the first weighting factors ignore a diametric chordal path used by the first chordal integration scheme;
applying second non-zero weighting factors to the second different chordal integration scheme, wherein the second non-zero weighting factors are applied to all chordal paths used by the second different chordal integration scheme;
detecting in the flow meter the one or more integration errors based on the first chordal integration scheme and the second different chordal integration scheme.
