A sliding groove 11 is formed on the outer surface of the sleeve 6. A sliding ring 12 is slidably connected within the sliding groove 11. The sliding ring 12 is fixedly connected to the fixing ring 10 via a connecting rod 13. Specifically, the sliding ring 12 can only slide relative to the sleeve 6 and cannot rotate.

Specifically, this arrangement can ensure that the flow rate of the liquid flowing through the Hall flow meter 2 is relatively stable, reducing detection errors.

[0031] Based on the above structure,

[0032] In one embodiment, a limit ring 14 is sleeved on the outer surface of the pipe 3. The limit ring 14 is divided into an upper fixed end 141 and a lower plug end 142. The upper fixed end 141 is fixedly connected to an existing crossbeam 143, and the plug end 142 and the fixed end 141 are connected by bolts 144. Specifically, the pipe 3 is arranged between the plug end 142 and the fixed end 141 and can rotate between the two ends.
