Method for determining a flow rate for a fluid in a flow tube of a flow measurement system, as well as a corresponding flow measurement system

摘要

Flow measurement system comprising a flow tube for the fluid whose flow rate is to be determined, wherein said system comprises at least three ultrasound transducer circuitry, wherein each circuitry comprises an ultrasound transducer arranged for transmitting ultrasound signals through said fluid in a transmitting phase, and for receiving transmitted signals from another of said at least three ultrasound transducers in a receiving phase, multiple receiving circuits, wherein each receiving circuit is arranged for reading out one of said at least three ultrasound transducers in a corresponding receiving phase thereof, and multiplexer circuitry ground arranged for selectively connecting each of said multiple receiving circuits to a different one of said at least three ultrasound transducers, respectively.
