METHOD FOR DETERMINING A FLUID FLOW RATE THROUGH A PUMP

A computer-implemented method for determining a flow rate of fluid flow at a target time through a pump, in particular a centrifugal pump, the pump being driven by a pump motor, the method comprising: receiving at least one set of previous parameter values including a first previous parameter value indicative of a first operational parameter of the pump motor at a previous time, earlier than the target time, and a second previous parameter value indicative of a second operational parameter of the pump motor at the previous time; receiving a current set of parameter values including a first current parameter value indicative of the first operational parameter of the pump motor at the target time and a second current parameter value indicative of the second operational parameter of the pump motor at the target time; computing the flow rate of fluid flow at the target time from the current set of parameter values and from the at least one set of previous parameter values.
