Abstract

An ultrasound flow measuring tube includes an ultrasound transmitter transmitting ultrasound energy toward a reflector in the tube, which reflects the ultrasound energy so that it is reflected from a side of the tube before reaching a second reflector. The second reflector directs the ultrasound energy to an ultrasound receiver. The reflectors direct the ultrasound energy along a spiral path in the tube.
