Claim 0:
1. A computer-implemented method for determining a flow rate of fluid flow at a target time through a centrifugal pump driven by a pump motor controlled by a processor, the method comprising:
receiving via the processor at least one set of previous parameter values including a first previously detected parameter value indicative of a first operational parameter of the pump motor at a previous time earlier than a target time, and a second previously detected parameter value indicative of a second operational parameter of the pump motor at the previous time;
receiving via the processor a current set of parameter values including a first currently detected parameter value indicative of the first operational parameter of the pump motor at the target time and a second currently detected parameter value indicative of the second operational parameter of the pump motor at the target time;
computing the flow rate of fluid flow through the pump at the target time via the processor from the current set of parameter values and from the at least one set of previous parameter values without reference to hydraulic parameters of fluid flowing through the pump, wherein the flow rate of fluid flow at the target time is computed by a machine learning model that compares the at least one set of previous parameter values at the previous time with the current set of parameter values at the current time.
