Abstract: A medical device (10) includes a device housing (12). An in-line thermal mass flow sensor (26) includes a heater (28) and at least one temperature sensor (30). The in-line thermal mass flow sensor is vertically mounted on or in the device housing. The in-line thermal mass flow sensor is configured to measure a flow rate of the fluid through the medical device. At least one electronic processor (18) is programmed to: read the flow rate of the fluid measured by the in-line thermal mass flow sensor; and detect at least one bubble in the fluid based on the measured flow rate.
