Abstract

The present invention relates to a system (100) for controlling fluid flow. The system (100) comprises a pump (102) and a controller (104) in communication with the pump (102). The controller (104) is configured to supply a drive signal to the pump (102) for providing a flow rate of the fluid through a fluid flow path for a predetermined duration (201), to receive a feedback signal outputted form the pump (102) after the predetermined duration (202), to obtain at least an electrical parameter data from the pump (102) after the predetermined duration (203), to determine at least one fluid flow path characteristic of the fluid flow path based on the received feedback signal and the obtained electrical parameter data (204), to determine a control signal based on the determined characteristic of the fluid flow path and a target fluid flow rate (205), and to output the control signal to the pump (102) for providing the target fluid flow rate (206). Further, the present invention relates to a method (200) of controlling fluid flow in the system (100). Accompanying drawing: [Fig. 2]
