A consumption meter, e.g. a water or heat meter, for measuring a flow rate of a fluid supplied in a flow tube. First and second ultrasonic transducers are arranged at the flow tube for transmitting and receiving ultrasonic signals transmitted through the fluid and operated by a flow measurement sub-circuit for generating a signal indicative of the flow rate of the fluid. A noise measurement sub-circuit operates a sensor arranged at the flow tube for detection of acoustic signals of the flow tube, and being arranged to generate a signal indicative of a noise level of the flow tube accordingly. This sensor may comprise a separate transducer, or the sensor may be constituted by one or both of the first and second ultrasonic transducers. The consumption meter may communicate data representative of the noise level via a communication module along with data consumed amount of water, heat etc. Such consumer noise level measurement at the consumer site allows collection of noise level data to assist in locating fluid leakages in a fluid supply pipe system.

Uplink data frames are sent from a measuring device to the data collection unit. Some of the uplink data frames are provide a time-limited access opportunity (AO) for receiving downlink frames from the data collection unit. A counter value (FC) in the measuring device is updated by adjusting the counter value for each non-used or unsuccessfully used access opportunity. An urgency indicator is transmitted to the data collection unit by at least some of the uplink data frames that provide an access opportunity. The urgency indicator depends on the counter value. Downlink frames are sent from the data collection unit to the measuring device according to a prioritization scheme, based on the urgency indicator.

A flow meter unit (1) comprising a flow tube (2), a housing (3) and a housing compartment (4), wherein the housing compartment comprises an electronic metering circuitry (5). The flow meter unit uses a first sensor arrangement (6) for determining a fluid flow rate or a fluid flow volume through the flow tube. In order to determine further physical parameters relating to the fluid a second sensor arrangement (7, 20, 30, 32, 60) is placed outside the housing compartment (4), is fluidically and mechanically connected to the flow tube and is in wireless communication with the electronic metering circuitry (5) via a short-range antenna of transmitter and receiver means (8, 8', 8'', 8''') placed in the second sensor arrangement and a short-range antenna (9, 31, 67) placed inside the housing compartment (4). The short-range antenna is positioned at a height in-between a long-range antenna and a bottom wall of the housing compartment. The solution has the advantage that the risk of fluid leakage into the housing when using fluid sensors is reduced and that such a second sensor arrangement is easy to replace or to retro-fit to an already installed flow meter.

SENSITIVE AND ROBUST FRAME SYNCHRONIZATION OF RADIO FREQUENCY SIGNALS
A method for detecting a constant envelope burst-mode radio frequency (RF) signal with a known periodic synchronization sequence (PSS) represented therein, e.g. to be for reading of data from utility meters. An incoming RF signal is transformed into a digital baseband signal (DBS), and the phase domain part is processed by: 1) applying a correlation algorithm to correlate the DBS with a synchronization pattern corresponding to the PSS. 2) filtering the resulting correlation signal for removing at least a DC component of the correlation signal. 3) down-sampling the filtered correlation signal (or the correlation signal) with a sampling time controlled by a clock aligned with amplitude peaks in the filtered correlation signal (or the correlation signal). 4) performing a decision algorithm on the down-sampled signal to determine if PSS is present in the incoming RF signal. Then, 5) generating an output signal indicating if the known PSS is present in the incoming RF signal, in response to a result of the decision algorithm. The steps 1)-5) serve to detect if an amplitude in the correlation signal indicates the presence of the known PSS. Preferably, a second decision algorithm serves to detect if periodicity in the correlation signal indicates the presence of the known PSS, and finally the results of the first and second decision algorithms can be combined, e.g. by a logic AND operation, to arrive at a sensitive and reliable PSS detection result.
