Abstract: An ultrasound flow meter unit, e.g., a unit forming part of a flow meter for ultrasonic measurement of a fluid flow. The unit comprises two ultrasound transducers 206, a circuit board 202 with an electronic circuit 204 arranged for operating the ultrasound transducers 206, and a common protection membrane 132, such as a sheet of metal, for protecting the transducers 206. The common protection membrane 132 forms part of a water-tight casing, such as an IP68 class casing. The two ultrasound transducers 206 and the circuit board 202 with the electronic circuit 204 are positioned within the water-tight casing and thus protected against damaging humidity. A glass sealed feed-through 128 can be used to provide external electrical contact to the electronic circuit 204, i.e. for outputting an electric flow rate signal. Such flow meter unit is highly versatile within many applications since it provides a compact and robust unit. The unit can be used with or integrated in many types of devices, e.g. flow meters, such as used in consumption meters for charging purposes or in many other industrial or home applications.

Abstract: The invention provides a pressure sensor device arranged for measuring a pressure in a fluid pipe system, e.g. a utility network. A measurement system with a pressure sensor serves to measure pressure in the fluid pipe system, and a data processing unit determines at least one statistical parameter in response to a plurality of pressure measurements. Data packets with the statistical parameter is then transmitted by means of a communication module, e.g. via a data network which serves for remote reading of utility meters. The statistical parameter is selected from the second, third and fourth statistical moments of the pressures measured with the plurality of measurements of pressure. The pressure sensor device in a battery driven form can be placed at remote locations in a fluid pipe system to monitor pressure transients, e.g. in a water distribution system. Especially, a time stamp may follow the statistical parameter(s) sent, such that it is possible to track pressure transient creating events on the fluid pipe system.

Abstract: The present invention relates to a consumption meter for measuring consumption data of either a hot or a cold liquid supplied to a consumer site (2). The consumption meter comprises a flow meter unit (5) arranged for mount at either an inlet side (3) or an outlet side (4) of the consumer site, and arranged for measuring a flow quantity of the supplied liquid; an inlet temperature sensor (6) for measuring an inlet temperature of the supplied liquid medium, and an outlet temperature sensor (7) for measuring an outlet temperature of the supplied liquid medium; a calculator unit (8) configured to determine consumption values based on the flow quantity, the inlet temperature and the outlet temperature. The consumption meter comprises at least two legally verified consumption registers (R1, R2) for storing consumption values verified for billing. Each of the legally verified consumption registers are associated with an operational state of the consumption meter, so that the consumption meter is capable of measuring legally verified consumption data for each of the at least two operational states. The operational state is determined at the consumer site from an input.

Abstract: The invention relates to a system of consumption meters (2) arranged in a communication network, where program data of the consumption meters can be updated via the communication network. A data collector (3) is arranged for updating the program data of a group of consumption meters over the network. This is performed by establishing a dedicated update session to each consumption meter of the group of consumption meters, and transmitting addressed update program segments to consumption meters in session. During the update session with a given consumption meter, any other consumption meter which is within communication range (8) will, if it receives the update segment, store it even though the segment is addressed to another meter. In an update session of a next meter, only segments not already stored from a previous session to another consumption meter are transmitted to the next meter.
