Description
Technical Field

[0003] The existing patent (publication number: CN213902480U) discloses a uniform tube flowmeter, including a circulation device, the circulation device includes a circulation tube, flanges are movably connected to the left and right sides of the circulation tube, filters are fixedly connected to the two opposite sides of the flange, bolts are slidably connected to the left side of the flange, the circumferential side threads of the bolts penetrate and connect the left end face of the circulation tube, and the circumferential side of the circulation tube is fixedly connected to the fixing column; a display device is arranged above the circulation tube; and a cleaning device is arranged in front of the circulation tube.
[0004] The above-mentioned comparative document points out that by setting a rust removal plate and a telescopic rod in the cleaning device, the water flow eventually drives the rust removal plate to rotate, which can clean the rust generated on the inner wall of the circulation tube, and the telescopic rod can be extended to drive the rust removal plate to move back and forth to clean the rust on the inner wall. By setting a filter, bolts and fixing columns in the circulation device, the filter can prevent small particles from entering the interior of the flow meter and damaging the internal structure of the flow meter. However, the device is inconvenient to use in places with a large difference in water level and shore. It cannot change the height of the circulation tube. If a fixing column is inserted into the side wall of the shore, the staff needs to lean over and tighten it. This operation is potentially dangerous, so a uniform tube flowmeter is proposed to solve the above problems. Utility Model Content
