Claim Text:
1. A method for controlling the operation of a pulsating pump, the method comprising: monitoring discharge pressure patterns caused by each stroke of the pulsating pump; using a computer processing unit to analyze each pressure spike in the discharge pressure patterns and arrive at derived calculations for stroke length, stroke frequency, and flow rate, wherein a width of a base of the pressure spike is used to calculate the pump stroke frequency and an area of the pressure spike is used to calculate the fluid pumped per stroke, or equivalently the pump's stroke length, and the pump flowrate is calculated using the fluid pumped per stroke multiplied by the stroke frequency; and implementing a pump control strategy, using the computer processing unit, based upon a set of operating rules and the derived calculations.
