Abstract
The invention relates to an ultrasonic measuring apparatus of the type having a measuring path which extends in a tube between two ultrasonic converters. More accurate measuring results are obtained by providing axially spaced inserts in the measuring tube for changing the velocity profile of the medium flowing through the tube so that the average of the upstream and downstream signals is substantially proportional to the mean flow velocity of the medium flowing through the tube.
