Abstract
A measurement apparatus () and to a method provide for the determination of a flow rate (v) and/or of a throughflow (Q) of a fluid () flowing in a conduit (). At least one first ultrasonic transducer () and one second ultrasonic transducer () permit a flow rate determination via the time of flight of an ultrasound signal. To further improve the determination of a flow rate of a fluid using ultrasonic transducers, in particular at very high flow rates, and to enable the measurement of very high flow rates, a noise-measuring ultrasonic transducer () is provided that measures the noise generated in on the flowing past of the fluid () in the ultrasonic transducer, and a control and evaluation device () is configured to determine the flow rate (v) using the noise measurements.
