Abstract

An ultrasonic, flow measuring device, comprising a measuring tube having a straight measuring tube axis, a transmitter for sending an acoustic signal on a first signal path, a receiver for receiving the acoustic signal on the first signal path and a number of reflection surfaces, on which the acoustic signal is reflected at least once on the first signal path, wherein minimum separations of at least three subsections from the measuring tube axis lie in the range 0.4-0.6 r, wherein r is the inner radius of the measuring tube.
