Claim Text:
1. A hybrid ultrasonic flowmeter (hybrid flowmeter), comprising: a meter body including a meter pipe wall; at least a first sensing plane including at least four ultrasonic transducers (transducers) positioned in a parallelogram arrangement on said meter pipe wall including a first transducer pair and a second transducer pair; a first ultrasonic reflector positioned between said first transducer pair on a first portion of said meter pipe wall (first wall portion), and a second ultrasonic reflector between said second transducer pair on a second portion of said meter pipe wall opposite said first wall portion; said four transducers having assembly angles and emission patterns for emitting an ultrasonic beam to provide a plurality of direct measurement paths including at least a first and second direct measurement path and a plurality of reflective paths including at least a first reflective path involving said first transducer pair and said first ultrasonic reflector and a second reflective path involving said second transducer pair and said second ultrasonic reflector, and a flow electronics module including a transceiver coupled to a processor having an associated memory storing a flow measurement algorithm coupled to said four transducers for causing said four transducers to transmit ultrasonic signals, for receiving sensing signals generated by said four transducers, and for determining a volume flow of a fluid flowing through said hybrid flowmeter.
