摘要： An ultrasonic flow meter for measuring a flow rate of a fluid. The meter has a polymeric housing comprising a flow tube with first and second fluid openings connected by a flow channel. First and second mounting faces are formed inside the flow tube by a reduction in the cross-sectional area of the flow channel. The second mounting face is arranged upstream of the first mounting face inside the flow tube with a cross-sectional area of the flow channel at the first mounting face being smaller than a cross-sectional area at the second mounting face. The flow meter further comprises a first flow insert forming a measuring tube and a first ultrasound reflector holder and being provided with a mounting flange arranged to engage with the first mounting face, and a second flow insert forming a second ultrasound reflector holder and being provided with a mounting flange arranged to engage the second mounting face. Further, first and second ultrasound transducers are arranged to transmit and receive ultrasonic signals through the measuring tube via first and second ultrasound reflectors fixated by the respective ultrasound reflector holders, so as to allow ultrasonic measurement of a fluid flowing through the measuring tube.

摘要： 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.
