ULTRASONIC METER

The invention relates to an ultrasonic meter for measuring a flow rate or flow volume, comprising a fluid inlet, a fluid outlet and a flow channel arranged between the fluid inlet and the fluid outlet, two ultrasonic transducers and at least one reflector for ultrasonic signals.To create an ultrasonic meter according to the preamble, in which fluid flow through the flow channel is, as far as possible, undisturbed in order to achieve an undistorted measurement result, it is proposed within the framework of the invention to arrange ultrasonic transducers outside the flow channel, wherein entrance and exit openings for ultrasonic signals, each running obliquely relative to the longitudinal axis of the flow channel, are provided between the ultrasonic transducers and the flow channel, and to arrange the reflector on the wall of the flow channel opposite the entrance and exit openings such that it reflects ultrasonic signals of the ultrasonic transducers.By mounting the ultrasonic transducers outside the flow channel and arranging the reflector in the region of the wall of the flow channel, it is ensured that the passage of liquid through the flow channel is not disturbed by these elements. A distortion of the measurement result is thereby avoided.
