This article analyses and explains the implications that dispersive materials have over the linearity in flow measurement when a Clamp-on ultrasonic flowmeter is used.
This is of capital importance because dispersive materials are
commonly used in the manufacture of transducer wedges and
The evaluation of this phenomenon has been tested by
experimental measurement. The used setup consisted of a water
flow calibration facility where a commercial Clamp-on ultrasonic
flowmeter was installed ...
