Abstract: A consumption meter arranged to measure a flow rate of a fluid comprising: a tube with two transducer holes in a wall of the tube; a meter housing arranged at the tube, comprising two transducer housings and a main housing; first and second ultrasonic transducers arranged in the transducer housings for transmitting and receiving ultrasonic signals propagating through the fluid; a control circuit arranged in the meter housing for operating the first and second ultrasonic transducers to generate a signal according to the flow rate of the fluid. The transducer housing comprises: an internal transducer housing element arranged at an inner surface of the tube and an external transducer housing element arranged at an outer surface of the tube to extend through the transducer hole in the wall of the tube such that the transducer housing is fixated to the tube.
