Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flowmeters, in particular to an externally mounted bracket type ultrasonic flowmeter sensor. 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. There are different types such as the Doppler method, the velocity difference method, the beam offset method, the noise method and the correlation method. Ultrasonic flowmeters can be used for non-contact measurement. Existing clamp-on transducer ultrasonic flowmeters do not need to stop the flow or cut off the pipe for installation. It only needs to install the transducer outside the existing pipeline. This is a unique advantage of ultrasonic flowmeters in industrial flow meters. Therefore, they can be used for mobile (i.e. non-fixed installation) measurement, which is suitable for the evaluation and measurement of pipe network flow conditions.

[0003] The existing patent (Announcement No.: CN214040193U) discloses a clamp-on ultrasonic flowmeter for water balance test, which relates to the technical field of test instruments. It includes an ultrasonic flowmeter body and a fixed adjustment mechanism, wherein the fixed adjustment mechanism includes a fixed ring, an elastic support rod, a bracket, a lead screw, a stopper, a clamp and a buckle. Several elastic support rods are evenly arranged inside the fixed ring, and the two ends of the bracket are respectively fixedly connected to the outside of the two fixed rings. The lead screw thread runs through the bracket, and the stopper is fixedly connected to one end of the lead screw. The outer side of the sensor of the ultrasonic flowmeter body is attached to the inner side of the two clamps and the side of the stopper away from the lead screw, and the buckle is installed at the opening of the fixed ring. In the process of implementing the scheme, the inventor found that the following problems in the prior art have not been well solved: the device does not have a structure that fits the arc of the pipeline, and there is a gap after installation, which makes it difficult to keep the device stable. The device requires manual measurement of the distance between the two sensors, which is more troublesome to operate. Utility Model Content
