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 15):
A method for the determination of a flow rate of a fluid flowing in a conduit, the method comprising the steps of:\n evaluating a time of flight difference of ultrasound dependent on the flow rate between a first ultrasonic transducer and a second ultrasonic transducer, namely of ultrasound that propagates on a measurement path from the first ultrasonic transducer to the second ultrasonic transducer and in the reverse direction from the second ultrasonic transducer to the first ultrasonic transducer, measuring, on the flowing past of the fluid, the noise generated at an ultrasonic transducer by one of the first ultrasonic transducer, the second ultrasonic transducer, and a third ultrasonic transducer, and determining the flow rate using the noise measurements.
