I would like to ask, if the water supply, and at this time to open the tap, there will be gas ejected from the faucet, but no water, intelligent water meters and old water meters will be the same as the word?
But now some water meters have improved these phenomena! But basically there is the phenomenon of rotation, that is, "walk" word, but not very much!
Water diversion meter, many water meters have the phenomenon of rotation, pressure and other factors, the water meter itself rotation;
Will go word, want to put out the gas.
