Abstract: The method serves the purpose of the acoustic leak detection in a district heating supply network (3), in which a heat transfer medium is circulated between a combined heat and power plant (1) and points of use (5). The points of use (5) have heat meters (10), which operate with ultrasonic flow meters, which operate with ultrasonic flow meters, which can be operated in a leak detection mode for the acoustic leak detection, whereby the acoustic signals detected in the leak detection mode are filtered to eliminate extraneous noises, in particular pump noises.

Abstract: The invention refers to a method for setting up an acoustic leak detection system in a fluid distribution network characterized by the following steps:
placing at least one first acoustic sensor (10) in the network
placing at least one acoustic signal generator (26) in the network at a location distanced to the at least one first acoustic sensor (10) along a pipe (4),
generating an acoustic signal by the acoustic signal generator (26)
evaluating whether the at least one first acoustic sensor (10) detects said generated acoustic signal, and
in case that said generated acoustic signal is not detected by said at least one first acoustic sensor (10), placing at least one second acoustic sensor (24) in the network at a location less distant along the pipe from the location of the signal generator (26) than said at least one first acoustic sensor (10).-

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 method for locating a leak (19) in a water supply network with a water source (11) and one or more water consumption meters (21, 22) on the consumer side. The method includes calculating a length of the pipe (17) between the consumption meter (21) and the leak (19) location based on a temporal temperature curve and a quantity of water flowing through the at least one consumption meter (21).

Abstract: A fluid consumption meter (2) is arranged to measure a flow rate of a fluid and has a control device (14) with a sound detection module (26) arranged to detect a sound in said fluid. The control device (14) is configured such that during activation of the sound detection module (26) at least one further module (20, 22, 24) of the consumption meter (2) not required for sound detection is in a deactivated state. A method is provided for detecting sound in a piping system.

Abstract: Fluid consumption meter comprising a noise detection module for leak detection measurements and a control device comprising a bi-directional communication unit. The control comprises a time synchronization module for time synchronization of leak detection measurements with an external device via the bi-directional communication unit with a time synchronization error of less than 1000 micro seconds. The control device is arranged to receive a leak detection control signal from an external device and to start the leak detection measurements at a point in time specified the received leak detection control signal.

Abstract: A method for acoustic leakage detection in a fluid pipe network (1) uses at least one ultrasonic flow meter (13) installed at a pipe (15, 17). The pipe connects a consumer site (3) to the fluid pipe network. The method includes detecting at least one sound wave traveling along the pipe and/or along fluid within the pipe from a sound source to the at least one ultrasonic flow meter, determining the traveling direction of at least one of the at least one sound wave, interpreting a sound wave of the at least one sound wave as a leakage sound candidate if the determined traveling direction of said sound wave is towards the consumer site, and interpreting a sound wave of the at least one sound wave as a background noise if the determined traveling direction of said sound wave is away from the consumer site.
