  • Apparatus for ultrasonically measuring the flow rate of a fluid in a measuring channel, achieving an attenuation of the parasitic signals
    Patent number: 10584991
    Abstract: An apparatus for ultrasonically measuring the flow rate of a fluid in a measuring channel including fluid supply passages at its ends, this measuring channel forming a waveguide made into a solid body, comprising at each end a transducer capable of emitting or receiving ultrasounds circulating in the axis of the channel, where each transducer includes a shell transmitting the ultrasounds, comprising a waveguide facing the measuring channel, and outside this waveguide shapes orientating the ultrasounds in directions different from that of the channel.

  • Method for controlling an apparatus for ultrasonically measuring the flow rate of a fluid in a measuring channel
    Patent number: 10480972
    Abstract: A control method for an apparatus for ultrasonically measuring the flow rate of a fluid in a measuring channel, including a measuring channel whose one end is equipped with a first transducer and the other end is equipped with a second transducer, each transducer emitting ultrasonic waves to the other transducer, and receiving waves generated by the other transducer, where, in a first step, the first transducer emits waves to the second transducer, and in a second step, which can be simultaneous with the first one, the second transducer emits waves prior to the reception of the waves emitted by the first transducer.
