Abstract: A radio communication device comprising a radio frequency circuit and a microcontroller arranged to control the radio frequency circuit. The radio communication device further comprises: a radio frequency reference connected to the radio frequency circuit and arranged to be the frequency reference of at least the symbol frequency; a MCU and a time frequency reference connected to the microcontroller. The microcontroller is arranged to determine a frequency error of the time frequency reference relative to the radio frequency reference by performing the steps of: transmitting a radio signal, and signal a timing signal on a control interface, comprising information on start of transmission and end of transmission of the radio signal; receive the timing signal from the radio frequency circuit and measure a transmission duration of the radio signal with reference to the MCU frequency reference and calculate a frequency error of the MCU frequency reference relative to the radio frequency reference based on the measured transmission duration of the radio signal and the number of symbols and the symbol frequency. Further, the microcontroller measures a time period of the time frequency reference with reference to the MCU frequency reference; and calculate the frequency error of the time frequency reference relative to the radio frequency reference.

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: A consumption meter for measuring consumption data of a supplied utility is provided, the consumption meter comprising: a housing with an opening, where the housing forms a closed compartment when the opening of the housing is closed with a cover; a communication module provided in the closed compartment; a front plate provided in the closed department and arranged adjacent to the cover, wherein the front plate has a first front plate surface facing the cover, and a second front plate surface facing opposite; and an antenna comprising an antenna body with an antenna conductive element, which is connected to the communication module; wherein the front plate has an indentation arranged between the first and the second front plate surfaces, and wherein the antenna body is arranged in the indentation. The consumption meter provides an antenna with a high transmission performance. Further, the antenna is mechanically supported, and is arranged inside the closed compartment, eliminating the need of any feedthrough across the housing wall.

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.
