Claim 19:
20. The system of claim 18 wherein the instructions for measuring the absolute-time-of-flight with respect to the flow of the fluid in the flow channel, are further configured for:
measuring the absolute-time-of-flight with respect to the flow of the fluid in the flow channel across a first acoustic path of the flow channel from the first transducer to the second transducer to determine a first absolute-time-of-flight; and
measuring the absolute-time-of-flight with respect to the flow of the fluid in the flow channel across a second acoustic path of the flow channel from the first transducer to the second transducer to determine a second absolute-time-of-flight, and calculating a third absolute-time-of-flight by the difference between the first absolute-time-of-flight and the second absolute-time-of-flight.
