ABSTRACT:
Disclosed is a method and apparatus for measuring the density of a liquid, such as a drilling mud, by continuously flowing a sample of the liquid through a container having a fixed predetermined volume. The container is supported by at least one bed of pressurized fluid. The pressure of the fluid is varied in response to fluctuations in the weight of the liquid sample in the container. A pressure transmitter monitors the pressure level in the bed and produces a signal indicative of the density of the liquid sample.
