Abstract
The invention relates to a multi-medium and temperature / pressure-adjustable ultrasonic propagation characteristic measuring device. The influence from temperature, pressure and medium to ultrasonic propagation characteristics cannot be comprehensively considered by an existing ultrasonic propagation characteristic measuring device, and the measuring result is inaccurate. The multi-medium and temperature / pressure-adjustable ultrasonic propagation characteristic measuring device comprises a gas circuit switching device, a pressure adjusting device, a sound speed measuring device and a temperature adjusting device, wherein the gas circuit switching device is connected with one end of the pressure adjusting device, the other end of the pressure adjusting device is connected with the sound speed measuring device, and the sound speed measuring device is arranged in the temperature adjusting device. High-pressure gas can be input through the gas circuit switching device, enter into the sound speed measuring device through the pressure adjusting device and be used as the medium, and temperature adjusting can be carried out through the temperature adjusting device. The multi-medium and temperature / pressure-adjustable ultrasonic propagation characteristic measuring device disclosed by the invention has the advantages that the influence from the temperature, the pressure and the medium to the ultrasonic propagation characteristics can be comprehensively considered, and the measuring result is more accurate.
