In an aspiration flow measurement system, a flow channel 108 is provided for receiving an aspiration fluid flow therethrough. The flow measurement system further includes an aspiration flow measurement chamber 102 and a flow sensor that is configured to generate a raw signal indicative of the rate of fluid flow through the flow channel 102. A control system 200 is configured to monitor the signals indicating the flow through the flow measurement chamber 102, and to determine when a value of the raw signal 250 is indicative of a disruption caused by the presence of an air bubble, wherein the control system 200 generates a filtered signal 260 of the flow rate that is exclusive of any signal values that are indicative of a disruption.
