Why does the new water meter rotate after changing the water meter?

The rotation of the new water meter is not a water meter failure, but because water is required to be replaced when the new water meter is replaced, so that air is introduced into the pipeline. The new water meter has a high sensitivity and is affected by the fluctuation of water pressure and the "water hammer" caused by the undischarged gas in the pipeline.

Sometimes there is jitter in the pipe, which is due to resonance. Most of the above phenomena occur because the water meter is installed too close to the water main, which is directly caused by water pressure fluctuations and the opening and closing of the faucet or valve by the neighbors. To solve this phenomenon, increase the length of the water pipe in the water meter, or increase the height of the water meter. When the pipe is shaken, adjust the inlet or outlet valve to remove the gas in the pipe with a large flow to eliminate the resonance.
