| Abstract: | Theory and circuit design of an ultrasonic fluid mud bulk density meter are discribed in this paper.Also experiment results of using this equipment to measure bulk densities of different fluid mud samples are reported.This equipment is mainly used for measuring bulk density of fluid mud on river bottom and deriving the profile of bulk density with depth,and so it can be judged whether water way dredging needs to be done. |

| Keywords: | ultrasonic attenuation fluid-mud bulk-density measurement |
