PUMPING SYSTEM, AND ALSO THE FLOW RATE IN THE PUMPING SYSTEM DETERMINING METHOD Russian patent published in 2018 - IPC F04D15/00 

FIELD: motors and pumps.

SUBSTANCE: group of inventions relates to the pumping system and the flow rate therein determining method. System comprises at least one liquid container (2), which comprises inlet (4) and outlet (6), with at least one pump (8), which is located at the inlet (4) or outlet (6), and control device (16), which comprises the flow rate estimation device for the flow rate through the container (2) determining. Flow rate estimation device is configured to use the system model for the flow rate determining therein. Model consists of at least two different sub-models: sub-model describing the inflow mode into the container (2), and sub-model describing the outflow mode from the container (2). Control device (16) comprises memory device, which is configured to store data recorded in the pumping system and the parameters estimation device, which is configured to determine the at least two sub-models parameters based on the stored data so, that the first sub-model parameters are determined simultaneously.

EFFECT: inventions are aimed at the flow rate through the container accurate determination.
