Abstract
An apparatus and method for determining a density compensated flow rate of a material flowing through a vibrating conduit. Signals are received from sensors affixed to the vibrating conduit. An uncompensated flow rate of said material is then calculated from the signals. A density compensation factor is then determined from the uncompensated flow rate and non-linear information relating density to errors in flow rate. The density compensated flow rate is then determined by applying the density compensation factor to the uncompensated flow rate.
