*GROSSLY* insufficient data for any sort of meaningful answer.

Characteristics of the liquid??

Characteristics of the solid??

Characteristics of the tube?

To wit, It's *EASY* to detect a full-pipe-diameter black solid after a
clear liquid.

Detecting occasional micron-size soot particulates in a 60" crude-oil
pipeline is another matter.
