Description

Technical Field

[0001] The utility model relates to the technical field of transducer detection devices, in particular to an ultrasonic flowmeter detection auxiliary device. Background Art

[0002] Ultrasonic flowmeter refers to a flowmeter developed based on the principle that the propagation speed of ultrasonic waves in a flowing medium is equal to the vector sum of the average flow velocity of the measured medium and the speed of the sound wave in a stationary medium. It is mainly composed of a transducer and a converter, and there are different types such as the Doppler method, the velocity difference method, the beam offset method, the noise method and the correlation method. In an ultrasonic flowmeter, the transducer and the converter are generally relatively arranged on the valve body of the instrument. The ultrasonic wave emitted by the transducer passes through the medium and is received and converted by the converter to obtain the flow rate of the medium. Therefore, ultrasonic flowmeters are widely used in heating pipes. When the transducer is tested to determine whether the transducer is in normal working condition, in order to quickly test, the transducer can be tested on site. However, when testing on site, the inside of the pipeline needs to be filled with medium. In the non-heating season or when it is inconvenient to inject water during the production process, there is no medium inside the pipeline, which makes it impossible to test the performance of the transducer on site.
