FIELD: measuring equipment.
SUBSTANCE: device for matching the ultrasonic signals comprises a tube having a first ultrasonic waveguide and a second ultrasonic waveguide extending into the tube such that ultrasonic transducers, connected to the ends of the ultrasonic waveguides, transmit the ultrasonic signals through the ultrasonic waveguides directly through the fluid passing through the tube.
EFFECT: improving the quality of the transmitted ultrasonic signal through the fluid in the pipeline and improving the accuracy of measuring the flow velocity of the fluid.
