Abstract
An HVAC flow measurement system () comprises an ultrasonic flowmeter () for measuring a flow of gas through a channel (). The ultrasonic flowmeter () comprises ultrasonic s transducers () arranged at a distance from each other in flow direction (f) and configured to emit an ultrasonic pulse into the channel () and to receive an ultrasonic pulse in the channel (). The flow measurement system () further comprises a processor () connected to the two ultrasonic transducers () and configured to determine and store transit times of ultrasonic pulses propagating in and against flow direction (f) along one or more than one path (R, R) in the channel (), and to determine the flow of gas using the transit times. A damper system () having a damper blade () arranged in the channel () is provided downstream of the ultrasonic flowmeter ().
