Abstract: A drilling mud monitoring system includes a single measurement chamber which is filled with a predetermined quantity of drilling mud. The chamber is weighed to provide a value representative of the density of the drilling mud. The time needed for the chamber to drain is measured to provide a value representative of viscosity. The system proceeds through a measurement cycle in which the chamber is filled, weighed, timed and washed. At the end of the wash step, the weight of the chamber is compared with an empty weight and if the chamber weighs too much, the conclusion is that drilling mud adheres to the chamber so it is washed again. An alarm is sounded if the mud weight is too low and/or too high or in the case of a machine malfunction.
