Apparatus and method for determining the flow rate output by each operational pump in a multiple parallel pumping system. The method comprises: measuring a flow rate of the combined fluid flow at a location downstream of the parallel arranged pumps 13; determining an average pump head for the operational pumps with a pressure sensor 14, 15, 16, wherein the pump head is assumed to be the same for each operational pump; determining a relationship between the pump head and flow rate for each pump based upon the measured combined flow rate and average pump head data, and based upon the assumption that the measured combined flow rate is equal to the sum of the individual flow rates for each operational pump; and using the determined relationships between pump head and flow rate to calculate the flow rate for each operational pump. |
