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 analyse 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.

A method for continuous online monitoring of a pulsating pump, comprising:
- monitoring discharge pressure patterns caused by each stroke of the pulsating pump;
- using a computer processing unit to analyse 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 being indicative of pump stroke frequency and an area of the pressure spike being indicative of fluid pumped per stroke, or equivalently the pump's stroke length, and the pump flowrate is fluid pumped per stroke multiplied by stroke frequency.
An apparatus for continuous online monitoring of a pulsating pump, comprising:
- a pressure sensor for monitoring discharge pressure patterns caused by each stroke of the pulsating pump;
- and
- a computer processing unit for analysing each pressure spike in the discharge pressure patterns to arrive at derived calculations for stroke length, stroke frequency, flow per stroke, and flow rate,
- a width of the base of the pressure spike is indicative of pump stroke frequency and an integral of the pressure spike or a mathematical function of it is indicative of flow per stroke or equivalently the pump's stroke length, and the pump flow rate is fluid pumped per stroke multiplied by stroke frequency.
