For a pumping station having a pump, a method is provided for calculating the flow rate, which includes the storage in a computer memory of a table correlating pumping rate for the pump with the pressure differential across the pump. Data is detected from which the differential pressure across the pump can be computed, and then a computer is utilized firstly to compute the differential across the pump, then to access the table in the memory to determine the pumping rate corresponding with the computed pressure differential, then to calculate the volume pumped during the time interval, then updating a totalizer in the memory by adding in the calculated volume.
