Abstract: A method and system are disclosed for monitoring the operating status of a materials distribution network having a distribution pipeline and a plurality of pumping stations located at spaced intervals along the pipeline for pumping material through the pipeline, wherein each station includes one or more pumps connected to the pipeline and one or more motors having shafts connected respectively to the pumps for operating the pumps. A plurality of primary input parameters at each of the pumping stations are sensed, including the shaft speed of each of the motors, the output torque of each of the motors, and the energy input to each of the motors. A plurality of values including the power produced by each of the motors, and the operating efficiency of each of the motors are calculated from the input parameters. The calculated efficiency values are displayed for operator use. The economic and financial savings or losses are calculated for management use.
