The principle is to detect the rate of change of pressure and flow in pipelines. When the pipeline is in a steady state, pressure, velocity and density distributions do not change over time. As the equipment (pump or compressor) power increases or decreases, changes in the velocity, pressure, and density distribution of the fluid are continuous.
