An HVAC flow measurement system () comprises an ultrasonic flowmeter () for measuring a flow of gas through a channel (). The ultrasonic flowmeter () comprises ultrasonic transducers () arranged at a distance L from each other in flow direction f. The ultrasonic transducers () are configured to emit an ultrasonic pulse into the channel () and to receive an ultrasonic pulse in the channel (). The flowmeter () further comprises a processor () connected to the two ultrasonic transducers () and configured to measure transit times in such a manner that a flow velocity of the fluid and at least one characteristic parameter(s) of the channel () are determined by using the transit times.
