Abstract
There is described a method for continuous online monitoring of a pulsating pump. A first step involves monitoring discharge pressure patterns caused by each stroke of the pulsating pump. A second step involves 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. A width of the base of the pressure spike is indicative of pump stroke frequency and an area of the pressure spike being indicative of fluid pumped per stroke. The pump's stroke length and the pump flow rate is fluid pumped per stroke multiplied by stroke frequency.
