Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flowmeters, in particular to an ultrasonic flowmeter which is easy to assemble and disassemble. Background Art

[0002] An ultrasonic flow meter is a flow meter 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 has different types such as the Doppler method, velocity difference method, beam deviation method, noise method and correlation method.

[0003] Nowadays, ultrasonic flow meters are mostly connected to pipelines using clamps. When using the clamp connection, the ultrasonic flow meter needs to be placed above the pipeline first. One person is needed to stabilize the flow meter, and then another person is needed to stabilize it using the clamp. The coordinated operation of the two people and the use of the clamp connection method make the disassembly and assembly of the ultrasonic flow meter more complicated. Secondly, since the ultrasonic flow meter has two sets of detection lines, the detection lines of today's ultrasonic flow meters are difficult to stabilize, which makes it easy for the detection lines to be loosened and fall off due to external influences.
