    Abstract: A fluid consumption meter (50) configured to measure a flow rate of a fluid and with a noise detection module (40) for leak detection. Also having a control device with a bi-directional communication unit (60) and being configured to receive a leak detection control signal from an external device (100), to set the fluid consumption meter (50) into a leak detection mode upon reception of the leak detection control signal, and to start a noise measurement for leak detection in said leak detection mode and to transmit data from said noise detection module, an to a leak detection system.

    Abstract: A system and a method for identifying a leak indication in a utility distribution system is described. A pipe network for supplying a utility to a multitude of service connections includes a plurality of acoustic sensors mounted at the service connections. The acoustic sensors are preferably integrated in ultrasonic flow meters. The method comprises the steps of obtaining information about a time of change of a fluid pressure and then establishing a first noise indicator from the noise measured by the acoustic sensors before said time of change, establishing a second noise indicator from the noise measured after said time of change; and then correlating one or more first noise indicators and second noise indicators with the fluid pressure to identify service connections subject to leak indications. A leak detection system based on a mathematical cross correlation of noise indicators and fluid pressure in a fluid pipe system is also described.
