Abstract: A method determines a fluid pressure at a fluid flow meter installed in a pipe network that is supplied with fluid at a varying and/or variable input pressure. The method includes recording input pressure information for a determination of a difference between input pressures in a first considered time-window and second considered time-window, aggregating statistical data of a plurality of fluid flow events and/or fluid volume consumption events during the first considered time-window and the second considered time-window, providing the aggregated statistical data to a head-end system (HES) that has access to the input pressure information and determining, by the head-end system, a fluid pressure at the fluid flow meter based on a change in the aggregated statistical data between the first considered time-window and the second considered time-window, and the difference between the input pressures in the first considered time-window and the second considered time-window.

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.
