1. A method for determining a pump flow (Q) of a pump, the method comprising:
calculating an inverse of a polynomial equation defining a DP-Q performance curve of a pump, wherein the inverse is a Q-DP polynomial equation defining the performance of the pump;
receiving a pump head (DP) value from a pump head sensor associated with the pump;
computing a pump flow based on the Q-DP polynomial equation;
comparing the computed pump flow to a preset target flow rate; and
automatically controlling a pump parameter of the pump such that the calculated flow rate becomes the preset target flow rate.
