The beam can be attenuated in transit due a number of phenomena, including optical attenuation caused by nature of the vapors in the beam path, and dust/dirt in the beam path to/from the material.

In this application, the strange shapes on the inside of the pipe can affect the velocity profile and, in turn, the flow measurement.
