Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flow testing, in particular to a flow channel structure of a multi-channel gas ultrasonic flow meter. Background Art

[0002] Multi-channel ultrasonic flowmeters mainly determine the flow rate of fluid by measuring the propagation speed and path of ultrasonic waves in the fluid. They are used to measure the flow of liquid and gas in pipelines to ensure the stability and safety of the production process. Single-channel measurement is generally only suitable for use in flow situations with ideal conditions, and it is difficult to ensure that the actual flow conditions of the fluid are effectively reflected.

[0003] Chinese patent CN218002613U proposes a flow channel structure of a multi-channel gas ultrasonic flowmeter, including: a channel structure, a mounting seat and a fixing device; the mounting seat is fixedly installed at both ends of the tube body and fixedly connected to the external tube body; the channel structure is opened on both sides of the tube body and is symmetrically distributed; the fixing device is arranged on the top of the tube body, and an external ultrasonic flowmeter is installed. A convex plate is arranged around the middle of the tube body, and a channel structure is arranged on the convex plate. The channel structure includes oblique cross channels and parallel cross channels, which solves the problem of single-channel gas ultrasonic flowmeter use scenario, and has a simple structure and is easy to install. It can more comprehensively reflect the fluid flow situation and make the test results more accurate. In addition, the multi-channel of the ultrasonic flowmeter can be used as a redundant backup. Even if an individual sensor is abnormal, the gas ultrasonic flowmeter can still work normally.

[0004] The above scheme effectively solves the problem of single-channel gas ultrasonic flowmeter usage scenario, and has a simple structure, easy installation, and more comprehensive reflection of fluid flow conditions, making the test results more accurate. However, the above scheme cannot filter impurities inside the gas or liquid. Impurities can easily enter the multi-channel gas ultrasonic flowmeter, which will affect the service life of the multi-channel gas ultrasonic flowmeter. In addition, the joints of the equipment are prone to air or liquid leakage, which will also cause a lot of resource waste and reduce the use effect of the flow channel structure of the multi-channel gas ultrasonic flowmeter.
