In this embodiment, since the first blocking member 241 is opened under a certain water pressure, by providing the above-mentioned exhaust box 420, the gas can be exhausted through the exhaust hole 401 until the exhaust box 420 is filled with water, and the floating member 430 is floated by the water to block the exhaust hole 401, so that the water pressure in the first conduit 400 can push away the first blocking member 241. Therefore, by providing the above-mentioned exhaust box 420, it can be ensured that the first blocking member 241 is opened and water is filled into each water meter 300 only after no air is in the first conduit 400, so as to ensure the measurement accuracy of the water meter 300.
