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: A water utility meter arranged to register the volume of water delivered to a consumption site through a distribution network and connect or disconnect the consumption site from the utility distribution network is disclosed. The water utility meter comprises: a flow sensor arranged to measure a flow rate and/or a volume of water delivered to the consumption site; a valve for connecting and disconnecting the consumption site from the distribution network; an actuator for opening and closing the valve; and a controller unit arranged to control the actuator. The controller unit is configured to connect the consumption site to the distribution network by operating the actuator to open the valve. After opening the valve the controller unit analyses flow rate and/or volume measurements from the flow sensor to determine if a reference profile is violated. If the reference profile is violated the controller unit will disconnect the consumption site from the distribution network by closing the valve.

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 turbidity measurement device for measuring turbidity of a fluid flowing in a flow tube. A first transducer transmits ultrasonic signals through the fluid in the turbidity measurement section so as to provide a first ultrasonic standing wave between the first and second section ends. A receiver transducer receives the ultrasonic scattered response from particles in the fluid flowing through the turbidity measurement section. A control circuit operates the transducers and generates a signal indicative of the turbidity of the fluid in response to signals received from the receiver transducer. Preferably, the device may comprise a second transducer for generating a second ultrasonic standing wave with the same frequency, and further the two transducers may be used to generate a measure of flow rate by means of known ultrasonic techniques. This flow rate may be used in the calculation of a measure of turbidity. Both turbidity facilities and flow rate facilities may be integrated in a consumption meter, such as a heat meter or a water meter.
