Abstract: Drilling mud is flowed through a valve assembly that is set at a particular open amount, measurements are taken of mud flowrate and a force exerted by the drilling mud onto a portion of the valve assembly, and density of the drilling mud is estimated based on historical data. The historical data is generated by directing multiple flows through the valve assembly, where the flows are at different flowrates, and at each flowrate different drilling muds having different densities are directed through the valve assembly. For each flow the valve assembly is adjusted to different open amounts, and a corresponding force exerted by the flow onto the valve assembly is measured. An example of the valve assembly is a mud pulser with a plug member that engages an orifice opening, a sensor in the pulser measures force exerted by the flow of mud.
