[0002] Flowmeter: An instrument that indicates the measured flow rate and / or the total amount of fluid in a selected time interval. In simple terms, it is a type of flowmeter used to measure the flow rate of fluid in a pipeline or open channel. Flowmeters are divided into differential pressure flowmeters, rotor flowmeters, throttling flowmeters, slit flowmeters, volumetric flowmeters, electromagnetic flowmeters, ultrasonic flowmeters, etc. Classified by medium: liquid flowmeters and gas flowmeters.

[0003] Flow meters in the prior art, such as liquid flow meters, are connected to pipelines during use. During the flow measurement process, if the flow rate of the connected pipeline is too large, this will cause impact on the connection, causing instability and possible leakage.

[0004] After searching, it is found that a liquid flow meter (publication number: CN219434149U) is disclosed in Chinese patent documents. The utility model belongs to the technical field of liquid flow meters, especially a liquid flow meter. In view of the problem that when measuring the liquid flow rate, if the existing liquid flow meter contains impurities, especially filamentary impurities, if they are entangled on the impeller, the impeller will rotate too slowly, and the liquid flow meter can no longer be used in serious cases, the following scheme is proposed, which includes a measuring tube and two second flanges, the outer wall of the measuring tube is fixedly mounted with a liquid flow meter body, the two ends of the measuring tube are fixedly connected with a first flange, and the outer walls of the first flange and the second flange are both provided with an arc groove. In the utility model, when the filamentary impurities in the liquid impact the triangular blade, they are cut off, and the larger impurities are blocked by the filter screen to prevent the filamentary impurities from affecting the rotation of the impeller. By arranging an arc sealing gasket, an arc block, a fastening screw and a U-shaped plate, the filter screen and the triangular blade can be replaced, but there are still the following defects:

[0005] Although the above-mentioned liquid flow meter cuts off filamentary impurities in the liquid when they impact the triangular blade during use, and blocks larger impurities through the filter screen to prevent the filamentary impurities from affecting the rotation of the impeller, the filter screen and the triangular blade can be replaced by arranging arc sealing gaskets, arc blocks, fastening screws and U-shaped plates.
