Publication number: 20240085378Abstract: A consumption meter, e.g. a water or heat meter, for measuring a flow rate of a fluid supplied in a flow tube. First and second ultrasonic transducers are arranged at the flow tube for transmitting and receiving ultrasonic signals transmitted through the fluid and operated by a flow measurement sub-circuit for generating a signal indicative of the flow rate of the fluid. A noise measurement sub-circuit operates a sensor arranged at the flow tube for detection of acoustic signals of the flow tube, and being arranged to generate a signal indicative of a noise level of the flow tube accordingly. This sensor may comprise a separate transducer, or the sensor may be constituted by one or both of the first and second ultrasonic transducers. The consumption meter may communicate data representative of the noise level via a communication module along with data consumed amount of water, heat etc.Type: ApplicationFiled: November 15, 2023Publication date: March 14, 2024Applicant: Kamstrup A/SInventors: Søren Tønnes Nielsen, Peter Schmidt Laursen, Jens Lykke Sørensen, René Gajda Kristensen, Martin Christian Høj Petersen
