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.

Abstract: The present invention describes a smart metering device being part of an advanced metering infrastructure. The smart metering device might comprise one or more sub devices such as: metering devices, actuator devices, sensor devices etc. The smart metering device includes a valve arranged to limit the delivery of a utility to the consumer. Moreover the smart metering devices includes a communication device including a transmitter and a receiver for wireless communication with a collector, utilizing a listen after talk mechanism to perform a two way communication to the head end system through a collector. The presented invention is especially beneficial for battery supplied smart metering devices. The advanced metering infrastructure will provide a given service level for communication between the meter and the head end system. The service level will be changed dynamically in order to meet the adequate service level at all times.

Abstract: Radio frequency communication method for wirelessly transmitting data packets between two communication nodes of a communication network, the method comprising the steps of generating a data packet including payload data and a first data check value a, transmitting the data packet from the first node to a second node; and determine whether the data packet is transmitted correctly by calculating a second data check value based on the received payload data and comparing the second data check value to the first data check value to; if the data packet is received correctly, transmitting from the second node to the first node an acknowledgement packet including a first acknowledgement check value wherein the first acknowledgement check value provides stronger assurances about data integrity of the received payload data than the first and second data check values; and at the first node, calculating a second acknowledgement check value based on the original payload data, and determining whether the data received at the second node matched the data originally sent from the first node.
