Abstract:
The invention relates to a measurement apparatus ( 10 ) and to a method for the determination of a flow rate (v) and/or of a throughflow (Q) of a fluid ( 14 ) flowing in a conduit ( 12 ) comprising at least one first ultrasonic transducer ( 18 ) and one second ultrasonic transducer ( 20 ) that 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, it is proposed that a noise-measuring ultrasonic transducer ( 18, 20; 24 ) is provided that measures the noise generated in on the flowing past of the fluid ( 14 ) in the ultrasonic transducer and a control and evaluation device ( 32 ) is configured to determine the flow rate (v) using the noise measurements.

Claim (Index 16):
The method in accordance with  claim 15 , wherein, in one of a teaching phase and when starting up the fluid throughflow, flow rates are first determined via the time of flight of ultrasound signals by means of the first and second ultrasonic transducers and the intensity of the noise is simultaneously measured by the noise-measuring ultrasonic transducer and the individual flow rate values are stored together with the respective associated measured noise values and the relationship of the value pairs is approximated by a mathematical function in an evaluation unit and the flow rate is determined with an increasing flow rate, when the flow rate measurement via the time of flight fails, using the then measured noise values of the noise-measuring ultrasonic transducer via the approximated function.
