Abstract
Flow velocity of a fluid is measured using a measuring sensor comprising a conduit with a conduit wall, and at least two ultrasonic transducer units (), each of which consists of an array of individual ultrasonic transducers (--) and defining a measuring path () between them in the conduit (). The ultrasonic transducer units emit ultrasonic signals and received ultrasonic signals are evaluated to determine the flow velocity. The individual ultrasonic transducers are driven with different phase, so that the ultrasonic transducer units provide a phased array. In order to achieve the most accurate measurement results possible, the ultrasonic transducer units contact the outside of the conduit wall (), and the conduit wall () is formed in the area of the contact with a wall thickness (w) that is less than half the wavelength of the transverse wave (λ) of the ultrasound in the conduit wall.
