A radio communication method involves utility meters installed at distributed installation locations with a data receiver. Data is received from the utility meters. Data is modulated on a received signal having a time-varying phase offset. Decision-directed phase tracking compensates for the time-varying phase offset. The compensated received signal is coherently demodulated to extract data. Extracted data is modulated to reconstruct a replica of the received signal. A phase offset prediction error—comparison between compensated received signal and the replica—and a phase offset prediction error covariance-divergence of compensated received signal and reference value and/or of phase offset prediction error and error reference value—are estimated and input into a Kalman filter. A Kalman filter output provides a prediction of time-varying phase offset in a feedback loop to compensate time-varying phase offset of received signal before compensated received signal is coherently demodulated to extract data.

A method for determining events in a network of consumption meters, in which an event is determined by grouping data wherein the event according to consumption meters which have detected this characterizing data. If groups of consumption meters match, this is determined as an event, the grouping being carried out according to the following criteria—temporal coincidence of the event—spatial concordance of the event—consistency of the event type. The spatial concordance is determined by determining and ranking the Euclidean distance of each of a plurality of consumption meters to everyone of the of others of the plurality of consumption meters, and by assigning the n closest consumption meters that have detected this characterizing data to a group of consumption meters.

SENSOR DEVICE WITH SYNCHRONIZED MEASUREMENT CAPABILITY
A sensor device, such as a consumption meter, with an LTE modem, a processor system connected with the LTE modem, and a sensor system comprising at least one sensor configured to sense a physical parameter and to generate an output accordingly to the processor system. The sensor device is configured to receive an activation time via the LTE network, wherein the activation time includes an absolute time and/or an indication of a specific LTE frame number. The processor system is configured to synchronize timing to a current LTE frame number in cooperation with the LTE modem. This may especially be done by the processor system signaling on an electric pin to the LTE modem which in response outputs a current LTE frame number, and along with the signaling on the electric pin, the processor system starts a timer. Thus, with the timer started at a known LTE frame number, the sensor device can calculate precisely to initiate a predetermined action time synchronized with the absolute time indicated in the received activation time along with a specific LTE frame number. The action may involve performing a measurement with a sensor in the sensor device time synchronized with the received activation time. This provides high precision time synchronization of a group of sensor devices, thus allowing performing measurements simultaneously by the group of senor devices. This allows group measurements which are not possible with the time precision of internal clocks of a group of sensor devices, and this time synchronization can be important for some applications, such as acoustic leak detection in a utility network.

CONSUMPTION METER AND REMOTE READING METHOD IN A UTILITY NETWORK WITH LINK MANAGEMENT
A consumption meter (Ml) arranged to determine a consumed quantity of a utility at the consumer site. The meter (Ml) has a communication unit with a transmitter and a receiver arranged for communication via a network, preferably an RF network. The meter can autonomously transmit data frames (DF) in accordance with a set of transmission parameters, e.g. data frames with data indicative of a consumed quantity. The meter can receive, within a limited time window (TW) following transmission of said data frame (DF), an acknowledgement frame comprising link data indicative of receipt of said data frame by an associated collector which has received the data frame (DF). Finally, the meter can adjust the set of transmission parameters for transmission of a subsequent data frame (DF) in response to said link data.
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.
