Abstract
An ultrasonic flow meter device includes a piping arrangement, at least two ultrasonic transducers, and at least two reflective elements. The piping arrangement includes a fluid passage extending through a tubular body. The at least two ultrasonic transducers are configured to generate and/or receive an ultrasonic sound wave and the at least two reflective elements are configured to direct the ultrasonic sound wave through a fluid passage in a measurement section of the piping arrangement between the at least two ultrasonic transducers in a travel path that is substantially Z-shaped. A width of the fluid passage in the measurement section is less than the width of the fluid passage at the ends of the tubular body, but the cross-sectional area of the fluid passage in the measurement section is the same as the cross-sectional area of the fluid passage at the ends of the tubular body.
