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: 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).
