[0002] Large-diameter water meters refer to water meters with a nominal diameter of more than 50mm. Large-diameter wireless remote water meters are composed of ordinary mechanical water meters plus electronic collection and transmission modules.

The meter body adopts an integrated design. It can record and save the user's water consumption in real time, or directly read the current cumulative number. Each water meter has a unique code. When the smart water meter receives the meter reading instruction, it can immediately upload the water meter data to the management system.

The connecting pipe can be replaced in time to ensure the stability of the flow rate at the water inlet end of the water meter.

[0019] 4. Compared with the prior art, the present invention sets four groups of connecting pipes at the front end of the water meter for alternate use, and detects the water inlet and outlet flow rates at both ends of the connecting pipes through two groups of flow sensors. When the data are different, the connecting pipes are automatically replaced, and the impurities filtered by the filter are collected in the collection box and then sent out from the side, so as to maintain the stability of the liquid flow inside the connecting pipes, and at the same time avoid damage to the water meter due to excessive accumulation of impurities.
