  • Common Pump Formula - M.G. Newell

    The simplest form of automatic chemical dose rate control is flow proportional control, in which the chemical dose rate is varied, by changing the speed of the dosing pump or adjusting the position of a regulating valve, in direct proportion to changes in flow past the dosing point. A flow meter provides the required flow signal.
