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 1):
A measurement apparatus for the determination of a flow rate and/or of a throughflow of a fluid flowing in a conduit, the measurement apparatus comprising at least one first ultrasonic transducer and one second ultrasonic transducer that are arranged with respect to one another in the conduit such that in operation the ultrasound transmitted and received on a measurement path from the first ultrasonic transducer to the second ultrasonic transducer has a time of flight difference dependent on the flow rate with respect to ultrasound in the reverse direction on the measurement path transmitted by the second ultrasonic transducer and received by the first ultrasonic transducer,\n a control and evaluation unit configured to control the ultrasonic transducers and to evaluate the signals of the ultrasonic transducers, and a noise-measuring ultrasonic transducer that is configured to measure a noise generated on the flowing past of the fluid in the ultrasonic transducer; and wherein the control and evaluation device is configured to determine the flow rate with reference to the noise measurements.
